Section 1: Introduction

Chennai Metropolis has been growing rapidly and the traffic volumes on the roads have also been increasing enormously. The Chennai Metro Rail project aims at providing the people of Chennai with a fast, reliable, convenient, efficient, modern and economical mode of public transport, which is properly integrated with other forms of public and private transport including buses, sub-urban trains and MRTS.

The metro being a new mass rapid transit system in Chennai, needs an effective wayfinding system, where the communica-tion elements facilitate the users in getting from point A to point B. Wayfinding systems in any transportation network should reassure users, create a welcoming environment and ideally provide answers to potential queries before the pas-sengers have to ask for assistance.

The design guidelines outlined in this document represent a comprehensive framework to create and apply a wayfinding and signage system for the metro stations, rolling stock and depots.These standards are intended to assist designers, developers, contractors, system operators and station managers in devel-oping and implementing a consistent signage systems across all stations, rolling stock and depots.

By careful and consistent application of this standard, the de-signer shall create a successful and appealing wayfinding sys-tem that should provide the required information to the users: Confirm they are at the correct start and finish point of an

individual journey Identify their location within the station building Reinforce they are travelling in the right direction Orient themselves within the station Identify any potential hazards Identify their destination on arrival Escape safely in an emergency

2CMRL Brand Identity



Section 2: CMRL brand identity

The CMRL identityThis symbol, chosen to promote Chennai Metro, is featured on numerous applications associated with the network, including system maps, station name signs, entrance totems and train liveries. This manual covers how the Metro symbol, should be implemented on passenger information and station signage.

Exclusion ZoneThe logo requires space around it in order to maximize its vis-ual presence. An exclusion zone around the logo prevents any graphic element from interfering with its integrity.The illustration opposite show the logo exclusion zone. Please ensure no other graphic elements or text are placed within these zones.

The vector format of the CMRL logo is provided in the CD - attached with this document.

3Visual Identity



Section 3: Visual Identity3.1 Basis of design

This section explains the rationale behind the graphic design approach, taking into account different categories of signs and passenger communications inside stations and on board trains.We have applied the following principles: Visibility and readability Viewing distances Information hierarchy Customer focusTogether these principles have contributed towards the crea-tion of a unified environmental graphics and passenger infor-mation system for Chennai Metro.

Visibility and readability The graphic standards developed for Chennai Metro need to be highly visible and instantly recognisable, particularly for application to signs in busy passenger environments. Since the purpose of all signs is to convey information, this shall be done clearly, concisely and consistently, to assist commuters. Signs tell passengers the layout of a station, where they are and in which direction they should go, assisting circulation, improving safety and providing reassurance.Furthermore, the clarity of information graphics on signs, combined with wayfinding strategy, can enhance the pas-senger journey, contributing to a feeling of confidence. This ultimately leads to a positive perception of CMRL as a pub-lic transport operator. Adherence to the standards of colours, typeface and their use in text and sign backgrounds is impor-tant to retain a desired level of visibility and readability

Viewing distancesThis chart, Figure 3.1.1, shows the distance at which certain sizes of lettering can be read by a person with average eye-sight. The chart shown here should be used to determine the minimum letter size for any specific sign. Other considerations such as architectural features or visual continuity, may influ-ence the choice of letter size but the optimum size should be used wherever possible.

Information hierarchyMessages on signs should be clear, logical and consistent in language, and use the minimum amount of text, supported by pictograms and arrows, as appropriate. This is important to minimise confusion at stations, including changes in transpor-tation modes, so that passengers understand the transport network and the various options available at specific points of their journey.

For ease of communication, too many messages on signs should be avoided. Messages should follow a system hierar-chy based on direction and the importance of information to passengers at each stage of their journey. The priority for di-rectional signs is to direct passengers to trains and other inter-connecting services and exits, including an indication of what passengers can expect to find at that exit, such as buses, taxis or any important landmarks.

The location signs shall not be mixed with direction signs. lo-cated at crucial decision points for passengers, for example, when deciding which train to board or whether to turn left or right. Where facilities such as toilets are nearby, location signs with pictograms should be sufficient to identify the facility.

Customer focusThe requirement of any transport operator is to make the sys-tem easy to use, particularly for first-time passengers. This is achieved by giving the passenger confidence. The design of the stations must provide this confidence, making it as intui-tive as possible to find the entrance, concourse and routes to the trains, as well as the way out or the route to connecting services. Information graphics and signing should enhance this process, confirming locations and making clear the lay-out of stations. Lack of clear directions can cause anxiety and it is important that passengers are reassured, CMRL has their safety and interest at heart. Signing as part of a comprehen-sive passenger information package is one of the most vital aspects of any transport system. The strategic placement of a unified family of signs is indispensable for guiding people safely and efficiently to their destinations, especially within busy station environments and public transport interchanges. A customer focused approach to the design of information graphics and signs is important for passenger safety and well-being, the smooth running of stations, and the projection of a strong Chennai Metro visual identity.

3.2 Basic Graphic elements

The Colours shown on this page are only as reference and should not be used for colour matching.

Actual colour swatches matching to PANTONE and RAL system should be produced for their respective medium and materials and duly approved before placing orders for paints, coatings, vinyl films or printing for the signs.




Typeface These fonts have been used for all direction signs, location signs, station name, title of information signs etc. Lettering must be shown in the specified colours, sizes and proportions unless stated otherwise. It is to be used in mixed upper and lower case (not all capitals). Capitals are used only for the be-ginning of a message or the beginning of a proper name. All direction and location signs shall have the message in 2 lan-guages, Tamil and English.Tamil, English and Hindi is used only on the station name sign on the platform.

These fonts can be purchased at: English and Tamil fonts: www.indiantypefoundry.comHindi font: www.modular-infotech.com





These fonts have been used for signs with running paragraph text for example, offences and penalties, safety messages, few information signs etc. Lettering must be shown in the speci-fied colours, sizes and proportions unless stated otherwise. It is to be used in mixed upper and lower case (not all capitals). Capitals are used only for the beginning of a message or the beginning of a proper name.

All statutory signs shall have the message in three languages: Tamil, English and Hindi.

These fonts can be purchased at: English and Tamil fonts: www.indiantypefoundry.comHindi font: www.modular-infotech.com


Typeface



Text representationUse of upper and lower caseOnly the initial letter of a sentence, facility name or informa-tion on a sign panel is an upper case letter (capitals). All other text is to be displayed in lower case. Studies and experience of design team have hinted that All CAPS text takes more time to read and appears as visual clutter in a multilingual signing specifically in combination with Indian languages and also leads to making the signs longer.

Use of abbreviationUse of abbreviation shall be kept to the minimum and only in places where due to space constraints the text has to be reduced. The abbreviations shall be avoided as its translation in Tamil will be difficult in reading and Tamil language is rarely in abbreviated form.

Translation between Tamil and EnglishThe translation shall be done keeping in mind the general vo-cabulary of people and relevance to the contextual language. Wherever possible the emphasis shall be on translation based on meaning than phonetic. The line colours represented by the colour names will be translated based on phonetics as the words would become a part of a spoken language of the city than that of written language. However the final decision and confirmation for the use of translated text will be given by em-ployer's representative.

AmpersandUse of ampersand should be avoided in favour of use of and, as Tamil language does not use symbols.

HyphenationPunctuation like full stops and commas shall not be used in short text messages. A hyphen shall not be used to indicate a time or day period. The term to or shall be used instead.Example : Monday to Saturday - 9:00 to 18:00

Time should be represented as a clock based on 24 hrs. Colon shall be used to differentiate hours and minutes instead of hy-phen or semicolon.

Dates and MonthsDates shall be displayed in order of day, month, year in both languages. Dot of Fullstop shall be used as separator for the date, month and year. Example : 20.03.2002

NumeralsAll numericals represented in English shall be of Kohinoor Latin font and numericals represented in Tamil shall be of Ko-hinoor Tamil font.

MoneyThe fares in the information sign shall be represented as D1.00 in English as well as Tamil . The decimal point shall be repre-sented with a full point.

Section 3: Visual Identity3.2 Basic Graphic elements



Pictograms have been recreated specially for Chennai metro system wide application. These designs have been inspired and referred with the ISO standards and global best practices in pictogram representations. Pictograms are useful because they are a form of shorthand for explaining directional or loca-tion messages, designed to be suitable for a local as well as an international audience.

Stand-alone pictograms are used to identify passenger facili-ties such as information points and toilets. There are different categories of pictograms covering: station facilities provided for passenger comfort; operational services to support the running of stations and the Chennai Metro system; and dif-ferent modes of travel, such as rail, taxi, bus and air transport available at transport interchanges.

Pictograms are always shown inside a rounded edges square box in white or yellow (in case of exits) against the grey back-ground, as illustrated. Every pictograms require space around it in order to maximize its visual presence. An exclusion zone around the pictogram graphic, shown in light grey, prevents any graphic element from interfering with it. Please ensure no graphic elements or text are placed within these zones.

Two or more pictograms can be combined as illustrated.

Pictograms where ever used shall be reproduced every single time from the original artworks and should never be redrawn.

New pictograms can be created using the grid shown here and matching the style, representation, visual look of these proposed pictograms.The newly designed and proposed pictograms shall be ap-proved by employer prior to its implementation.

Directional arrows have been designed to be highly visible and recognisable from a distance. Their correct application should aid the clear identification of directional signs within a busy station environment ensuring messages on signs are quickly assimilated and understood. The arrows are designed for passenger use at relatively close distances and therefore do not necessitate the same scale as those on traffic or road signs.

The use of white arrows against the blue background achieves good contrast to aid visibility and help reduce glare.

Arrows are rotated at 45 increments to indicate each direc-tion. Arrows centred in a 168mm x 168mm square box on signs. Directional arrows should be used as illustrated in this manual and not redrawn or modified in any way.

Basic rules for the use of arrows:

Arrows indicating directions to the left, straight ahead or down should be placed on the left hand side of the message. Arrows indicating directions to the right should be placed on the right hand side of the message. Arrows indicating oblique down and straight down must only be used for a change in level - i.e. stairs, ramp or escalator.Arrows indicating oblique up and straight up can indicate di-rection across open areas as well as a change in level.

45 degree / oblique arrows shall be used very carefully only at following instances Showing a change in level, i.e. movement above or below

at the staircase. Showing a prominent location/third direction in the

same sign panel which is distinctly accessed between the straight ahead and right/left directions.

In open areas where a person can actually walk in an ob-lique direction between the straight and left/right.

These should not be used in narrow corridors.

All sign sizes and proportions have been based on a 75 X 75 grid to retain a consistent visual look and limit the number of different sizes.

The ratio of the size of text and line spacing or leading shall follow the measurements as illustrated.

All signs shall follow the same sequence of languages (Tamil on top, followed by English and then Hindi) and the same pro-portions as shown here.

In certain circumstances secondary or subsidiary text is re-quired on signs, for example, to explain an exit direction in more detail by giving the street name, or a prominent land-mark at that exit. To maintain the emphasis on the direction to the station exit, it is recommended secondary text such as street or building names be shown at smaller sizes than the standard text size for signing. This applies to both Tamil and Latin typefaces.

Digital templates for multilingual sign layouts accompany this manual in separate folders on the disk version.

Please contact employer's representative for guidance on any sign which might be an exception to the above rule, for exam-ple, because of limited space.

DESCRIPTIONDirectional or wayfinding signs are key information providers for passengers navigating busy station buildings from the en-trances via the concourse to the platforms, and vice versa to the station exits. Most passengers read directional signs while on the move, albeit at walking pace, and from various viewing angles.

Sign composition SIGN TYPE: DT (direction to trains)The layout of information on directional signs has to follow a the hierarchy. The sequence for graphics on signs begins with the directional arrow, supported by a pictogram showing the service or facility a passenger may be aiming for (such as a train or tickets) with text in Tamil and English confirming the message.

Arrows are the most important elements of directional signs and are always centred in the end module, on the left for di-rections to the left and on the right for directions to the right.

Pictograms are then positioned after the arrow, onto the pic-togram panel. The pictogram panel ranged left for directions to the left and ranged right for directions to the right. The pic-togram shall be positioned on the pictogram panel as per the template. A maximum of three pictograms is permitted in a single sign array but use of 3 pictograms shall be very limited and preferably be avoided.

The direction signs are laid out in Tamil and English (Latin) text. Tamil text is always placed above the Latin text, as shown in the example on this page. The ratio of the size of text and line spacing or leading shall follow the measurements, already described in the sign layout section.

Sign compositionSIGN TYPE: DE (direction to exit)These are essentially the direction signs to exits and use the same layout principles as that of sign type DT. To clearly dif-ferentiate exit signs from all other signs, the colour of the pic-togram panel, pictogram fill colour, arrow and primary text is in yellow.

PLACEMENT PRINCIPLEThese signs shall be placed where a passenger has to make a decision of choosing a direction, either towards trains (DT) or towards exit (DE).The strategic positioning of directional signs assists passengercirculation around stations. It is important that directional signs are clearly visible and recognisable from a distance as well as reliable and authoritative.

PERFORMANCE SPECIFICATION Directional signs are internally illuminated unless speci-

fied otherwise. A sign face in rigid translucent substrate with graphics in

cast vinyl as per specified colours plotter cut and pasted. A protective over laminate shall cover the sign graphic on

the sign face fixed inside a Stainless steel frame. A MS sign box receives the Stainless steel sign frame on

2 sides for a double sided sign and 1 side for single sided sign.

The Pictogram panel shall be powdercoated to match specified colours with cutouts for router cut pictogram panels to project out and give a light hallow and illumina-tion.

For all pictograms on grey background, only the picto-gram illustration(in white or yellow) illuminates and the background shall not illuminate. Whereas in case of line colour pictograms, the pictogram will be entirely backlit.The sign face is all opaque allowing only text and symbols to be illuminated

FIXINGTypically suspended, projected and wall mounted inside the station environments.



Typical sign layoutsShown here are the typical layouts in direction signs, with two line and three line text.

Overall sign lengths shall be in multiples of 300mm, to retain a consistent visual look and such finite dimensions assist in coordination with other on site elements like wall panelling, cladding, door openings, counters etc. For instance, a sign overall length can be 2400mm or next size can be 2700mm, but there cannot be a sign with 2500mm overall length.

The layout of directional signs is proportionally based on the permitted sign height of 300mm or 375 mm depending on the number of text lines as illustrated. Margins at the left and right hand sides of signs as well as at the top and bottom are consistent irrespective of sign length.

The pictogram panel also increases in modules along the length, with every pictogram at a spacing of 37.5mm from the other. A maximum of three pictograms is permitted in a single sign array.

*These compositions shall be avoided and very rarely used.

**In case of 3 line exit signs the pictogram panel can accommo-date 4 smaller secondary pictograms, as illustrated. The second-ary pictograms may show other modes of transport available after exiting the metro station, for example, bus, auto, suburban railways or MRTS.

Combined signs provide a number of messages in one loca-tion. For Chennai Metro, signs arrays are joined on the same sign panel with pictogram panels added on top. The sign face will be a continuous panel separated with a white band. The pictogram panel is made for each panel and mounted onto the sign box with a small gap between panels when stacked, as illustrated. . The lower most pictograms showing the char-acteristic feature of projecting below the sign with rounded corners.

The maximum number signs stacked in a single location must not exceed three. If more than three messages/choices of di-rection are required in one location then consideration must be given to using additional signs.Arrow placement should follow the rules outlined earlier in this section. Arrows should never point into the sign or at an-other line.In case a one pictogram sign is stacked with a 2 pictogram panel, the panel for one pictograms shall be made as wide as the 2 pictogram sign message.

Sign alignment arrow orientationBy definition all directional signs contain arrows and it is im-portant that consistent rules are applied for arrow orientation to avoid confusion among passengers. Arrows pointing to the left, upper left or lower left, are positioned on the left aligned for the signs, adjacent pictograms and text follow and range from the left.Arrows pointing to the right, upper right or lower right are po-sitioned on the right of the sign, adjacent pictograms and text follow and range from the right.

When directions are signed straight ahead or straight down, the arrow can be shown on the left or the right, depending on sign location and the direction of other arrows if more than one direction is shown on the same sign. Under no circum-stances should arrows point into a sign.

Dynamic direction sign

4.1 Direction Signs

SIGN TYPE: DD1P, DD2P

DESCRIPTIONThe selection of the direction of the train is done basis the end station on that line on either side on that station. In a growing system like Chennai the lines extend bifurcate and also have running of partial services. During construction phase the lines open phase wise and the end stations change. At a terminal station with multiple platforms - trains for a spe-cific direction are not always bound to start form a specific platform to maximise the flexibility of the system and cater to the peak hour traffic. In above cases a sign with dynamic information clubbed with fixed information become very useful for users to navigate and make decisions.This sign will have a dynamic LED/LCD based display at the bottom of a typical 2 line sign. The layout of information on this sign has to follow the hierar-chy and measurements as illustrated.

PLACEMENT PRINCIPLEThis sign is placed where a passenger has to choose a platform and its direction.

Figure 4.1.11 DD2P - Direction Dynamic 2 Pictograms

Platform exit direction signSIGN TYPE: DPE

DESCRIPTIONOn platforms signs are mainly required to provide exit infor-mation to passengers getting off the trains.

The layout of information on platform directional signs has a different sign composition with text in the centre and direc-tions to lifts and stairs on either side.

The hierarchy of information and spacing all follow the meas-urements as illustrated.

PLACEMENT PRINCIPLEThese signs shall be placed only on the platforms, directing towards nearest stairs and lifts for exit.

Suspended Face mounted Projected

Direction signs can be installed at stations using various fixing methods:Suspended signsDirectional signs suspended from station ceilings should be fixed at a height of 2500 mm to the bottom of the sign from the finished floor level, as illustrated.The signs are suspended using hollow stainless steel pipes or tubes which shall house the power/data cable in a protec-tive sleeve for illuminated signs/dynamic signs. Bushings are required to protect the power cable and for safety at every junction.The suspenders should offer height adjustable to take ac-count of misaligned ceilings or beams to install the sign in a spirit level horizontal position. Signs in exposed areas subject to movement, such as swinging in high winds or when a train passes at speed, should be adequately designed to counter the imposed loads and deflections. Care should be taken to minimise the swinging of signs below a threshold of visual un-easiness for a person standing below. Ideally, a safety wire or chain should also be used to secure the sign in such a case. All visible suspenders below the false ceilings and also at lo-cations without false ceiling shall be made in Stainless steel while the suspensions inside the false ceilings can be made in Galvanised Mild steel.

Projected signsProjected signs should be fixed to the wall at a height of 2500 mm to the bottom of the sign from the finished floor level, as illustrated. A diagonal bracing wire shall be used for adequate support and rigidity. Sign brackets should be mounted with a shadow gap to compensate for uneven wall surfaces

Wall mounted signsWall mounted signs shall be fixed at a height of 2500mm to the base of the sign from the finished floor level, as illustrated.Sign casings should be mounted with a shadow gap to com-pensate for uneven wall surfaces. Signs should always be lev-elled horizontally to a spirit level alignment.For signs requiring fixing screw heads, these should be hidden wherever possible. Stainless steel should be used for any vis-ible upright posts, suspended ceiling rods, frames and other visible fixtures or fittings at all times.

Structural designThe Structural design for the suspenders shall be done by ap-proved structural engineer for all the dead and imposed loads as per the site conditions supported with the calculations supported with the basic data and safety factor assumptions. These should accompany the drawings showing the required cross-sections and permissible deflections for various mem-bers.

SIGN TYPE: DEL

DESCRIPTIONFor a passenger exiting the station, these signs assist in identi-fying the major landmarks close to the exit. This acts as a direc-tory listing for the landmarks accessible from the specific exit of the metro station.

These signs when placed close to the access to corridors at the concourse level should have an arrow and strategically placed just next to the start of the corridor.

These signs may be composed without an arrow as well, in the situations where it is placed at the exit gate.

PLACEMENT PRINCIPLEThis sign is placed where a passenger chooses an exit, based on the landmarks given. These can also be repeated at the exit gate.This sign is, at times, placed along with the Local area maps.

PERFORMANCE SPECIFICATIONThese signs are treated as poster panels and not illuminated.

FIXINGThese signs shall preferably be wall mounted and coordinate with the wall panelling on the interior walls of concourse. This sign shall be placed within a height of 770mm to 2100mm from ground. These should have least projections and ideally are expected to be flush to the wall panel face.

Depot direction signs

4.1 Direction Signs

DESCRIPTIONDirectional or wayfinding signs are key information providers for visitors, staff and services working and visiting the Metro system Depots. The signs at depot continue the visual identity designed for the Metro system and the illustrated designs in-dicate expected text layouts and representations for the signs.

SIGN TYPE: DPT-DThe layout of information on directional signs has to follow a the hierarchy. The sequence for graphics on signs begins with the directional arrow and the message with text in Tamil and English confirming the message.

Arrows are the most important elements of directional signs and are always centred in the end module, on the left for di-rections to the left and on the right for directions to the right.

The direction signs are laid out in Tamil and English (Latin) text. Tamil text is always placed above the Latin text, as shown in the example on this page. The ratio of the size of text and line spacing or leading shall follow the measurements, already described in the sign layout section. The sign are for use in interiors and exterior environments of the depot and sizes of the text shall be used accordingly as illustrated.

PERFORMANCE SPECIFICATIONDirectional signs for Depots are non-illuminated utilising re-flecting text for outdoor signs and opaque case vinyls for the indoor signs over a Aluminium sign face with specific colour. The structure for posts, suspenders and brackets shall be made in Stainless steel.

FIXINGTypically suspended, projected and wall mounted inside the station environments.




Section 4: Sign Types4.2 Location Signs

DESCRIPTIONLocation signs, also referred to as destination signs, identify metro entrances, buildings, counters, rooms, facilities, places and spaces.

Signs identify the facility/place and in a manner to represent and make a user know that he has reached.Typical locations signs are - The name of the station on a plat-form, Platform numbers, ticket counters, TVM locations, door-names and the main exterior signs identifying the station.Importantly, location signs do not include arrows announce the place/facility and are a sort of confirmation that is required as a user follows the direction signs to reach the place.

SIGN TYPE: LThe layout of a location signs has elements very similar to the direction signs consisting of a sign face and a pictogram panel. The pictogram panel identifies the place/facility and becomes a connect to the direction signs which lead to the facility. The signs face has text supporting the pictogram identifying the facility.

The pictogram panel has flexibility of aligning centrally or off-center along the entire length of the sign face. The pictograms shall be positioned on the pictogram panel as per the tem-plate. A maximum of three pictograms is permitted in a single sign array but use of 3 pictograms shall be very limited and preferably be avoided.

The location signs are laid out in Tamil and English (Latin) text. Tamil text is always placed above the Latin text, as shown in the example on this page. The ratio of the size of text and line spacing or leading shall follow the measurements, already de-scribed in the sign layout section.

The location signs are further classified into various types as a result of their typical placement for specific location/facility.

PLACEMENT PRINCIPLE, PERFORMANCE SPECIFICATION and FIXINGUnlike the direction signs, the location sign types vary a lot in their form, design, sign composition, details and illumination requirements and have been elaborated in next pages indi-vidually for their placement principle, performance specifica-tion and fixing.

SIGN TYPE: L1

DESCRIPTIONIdentifying the Metro stations is going to be important for the first time users of the system as well as visitors unfamiliar with the public transport network in Chennai. In case of elevated stations, the station structure and the viaduct undoubtedly stand out in the city skyline but the exact name is important. In due course of time it becomes a landmark of sort for people to orient themselves while moving in the city. These signs are specifically for use in elevated stations.

As a very basic option - Singular CMRL logo, is an optional sign that can be placed at highly visible locations (where the archi-tecture permits) for identifying a station building. (Fig 4.2.2).

The Station name sign is mandatory and must be used, on the exterior of station buildings visible from a distance on the approach, that will aid recognition of the station, helping pe-destrians and motorists easily identify the stations. The sign comprises of the stations name in two languages: Tamil and English supported by the Chennai Metro symbol, as illustrat-ed.This sign uses a blue panel with 3D letters mounted on it, along with a white projected panel (powder coated in RAL 9010) in the centre with the 3D CMRL logo on it.

The sign layout is adjustable in scale so that it will fit the avail-able space provided the minimum x dimension in the layout is 220mm. The size of the text is selected and the layout shown here is scaled accordingly retaining proportions, placement and relationships between the various elements. Actual size and location of the sign to be approved before execution.

PLACEMENT PRINCIPLEThis sign is placed on external walls of station building at high visibility locations for identifying the station. There may be multiple signs on a single station depending on the approach to station. The station name may be installed on the buildings where the station has greater visibility on the longitudinal side or at the end of the station box immediately over the road passing below the station.

PERFORMANCE SPECIFICATIONExecuted as channel letters or profile cut flat letters out of thick aluminium sheets finished with Powdercoating / PU painting for exterior durability, to match the specified colours for an exterior application. Sign execution placement and fix-ing details should be well coordinated with the architectural treatment at the location.The sign shall be either externally illuminated, or backlit.

FIXINGMostly fixed on building facades over the station building.

SIGN TYPE: L2

DESCRIPTIONTotems are designed to be prominently visible structures placed close to station entrances to identify the entries. Totem signs are double sided structures that carry the Chennai Metro symbol to make them easily recognisable from a distance.

There is an interchange information panel, on which informa-tion about the metro lines and other modes may be given. It displays the line colours on which the particular station lies. In case of interchange stations, both line colours will be dis-played, as shown in the illustration. Train timings are displayed along side each line colour. This panel can also be used to show other transport interchanges, using pictograms, which are thereby indicating this station to be a interchange be-tween metro and other transport mode.

There is a space for an area map/system map on the totem, which is useful for the passengers exiting/entering the station respectively. Keeping all these various elements and propor-tions of the totem consistent, the overall size of the totem may be modified slightly,if required, based on site conditions.Designed as a projected version and floor mounted version for use at elevated and underground station entrances re-spectively.

PLACEMENT PRINCIPLEA projected totem should be placed off wall next to the station entry clearly visible form the approach roads. A floor mounted totem should be placed in very close proximity to the station entry without interfering with people movement and the sta-tion entry structure.

PERFORMANCE SPECIFICATIONUse of rigid non-corrosive cleanable sign faces with provision for maintenance and structure designed to withstand the imposed loads. The sign face and panelling shall be framed inside a brushed finish stainless steel frame with UV treated and laminated print of information signs fixed within lock-able secure frames behind clear polycarbonate. This structure shall be illuminated, so that only the Metro logo, line colour pictograms, text panels and the maps illuminate. The floor mounted totem shall have well designed internal structure and a concrete foundation

FIXINGThe floor mounted totem(figure 4.2.6) shall be installed in case of underground stations due to lack of a prominent struc-ture. The projected totem (figure 4.2.7) shall be used in case of elevated stations, projected at the entry/exit opening at a minimum height of 3 meters. There may be cases of elevated stations where the entry is hidden, in this case floor mounted totems can be installed.

Section 4: Sign Types4.3 Information Signs

DESCRIPTIONInformation signs help passengers to understand how to use the Metro system. The purpose of these signs is to provide orientation through Metro maps and area maps and enable passengers to plan their journey in the metro system and in a reasonable walking distance around the station. These also include user information, rules and regulations, fare structure, fare chart etc. These are necessarily printed posters placed in frames on wall mounted or floor mounted structures across the stations.These poster contents can also be converted for Digital appli-cations and displayed on LCD/flat screens is placed at stations.

Typical information sign posters are System map Line maps Area maps Station maps Fare types Fare chart System user guideMore information signs/posters can be created for display-ing other information and messages which metro operations would need beyond the above list. All these would use the same template and guidelines for their design.

All these signs use the same sign structures described and il-lustrated on this page.The next set of pages in this chapter give the details, graphic templates and specifications with process of creation for few posters.

PLACEMENT PRINCIPLEInformation signs are placed in unpaid areas helping ticketing and planning the journey, The line maps placed in paid con-course help in confirmation and orienting a passenger in the direction of travel while the area maps at entrance, paid and unpaid concourse are important for inter connectivity with the immediate station vicinity areas

PERFORMANCE SPECIFICATIONRigid, non-staining and anti-vandal finished cladding of Stain-less steel over mild steel structure with pedestal. The informa-tion posters shall be placed inside panels made up of secured lockable snap fit aluminium frame finished in colour as speci-fied. The poster panels shall be digitally printed and placed inside the frame behind clear Polycarbonate sheet.

FIXINGMost signs will be wall mounted while some made as free standing with information on single or both sides. All wall mounted signs shall coordinate with the wall panelling on the interior walls. Max 2 panels shall be combined in a single structure.

The standard layout provides a header and borders around the remaining three sides, leaving a clear space in the mid-dle. The proportions of the header band are always the same depending on the original size of paper.

The header band is used for titles, and the inclusion of the Chennai Metro symbol to indicate the authority of the infor-mation. Blue is used for the header and borders, with white for the background colour for body copy. At the bottom is a section for legend, that explains the symbology used in the poster. The layout grid for text allows for the use of one, two or three languages on posters.

It is important passenger information is consistently present-ed in the recommended formats to underline the authority and reliability of communications from the network operators.

The graphic here also use a 75mm grid and sizes derived using this grid to the nearest size matching the global standards of A series paper sizes, as defined by ISO 216- A0, A1, A2 etc.Any structure or framing for these signs shall be out of the graphic area.

All information signs when printed or made available to the public must display an issue date and version in the bottom right hand corner. For station specific signs - the station name should be included. Digital templates for map layout, colours and details accompany this manual in separate folders on the disk version.

The posters will always be made in portrait format for a hori-zontally compact design.

The guidelines outline use of texts sizes, typical colour palette and rule for the layout creation.

The colour matching is critical for all digitally printed posters and consistency shall be maintained across all the individual prints by carefully calibrating the printers for the project re-quirements.

All the designed graphics shall be approved by the employer and the employer's representative before printing and pro-duction for their design, content, messaging, language trans-lations and finally for colour matching.

System maps communicate valuable information to passen-gers and can be an important corporate statement, acting as a unifying feature introducing the Chennai Metro system and initial Metro lines.

The Chennai Metro map is orientated North upwards with lines drawn at 0 degrees, 90 degrees and 45 degrees. No oth-er angles are permitted. Station names are always set hori-zontally in two languages, Tamil and English, and arranged either side of the Metro lines to be clearly legible.

Station locations are placed relative to each other in close approximation to their geographical position. Where appro-priate and where geographical positioning allows, spacing between indicated stations is kept closely related but not ex-actly as per the real distance between them in the alignment.

The map is a useful aid to passengers planning a journey on the Metro, showing stations, train directions, and the inter-connections between Blue line and Green line and other rail-ways and major transport systems in Chennai.

The other railway systems - MRTS and Suburban railway is represented for showing points of interchange.

All system maps when printed or made available to the pub-lic must display an issue date in the bottom right hand corner. Digital templates for map layout, colours and details accom-pany this manual in separate folders on the disk version.

The names of all Chennai Metro stations are shown in two languages, Tamil and English where space allows.Line colours are used to show individual lines, such as the Blue Line and Green Line, with stations indicated by tabs in the appropriate line colour. At interchange stations, rounded thick border white squares are shown covering both line at that interchange station, as illustrated.

The system map is designed as a specific artwork and should be reproduced from the original artwork.

Line maps are simplified representations of the system map or a single in a narrow linear horizontal or vertical space.

Line maps are used at the following locations Paid concourse Platform Inside rolling stock

Line map - Paid concourseThe line map format illustrated here is recommended for use on the approach to platforms, where the passenger needs to decide which platform he or she needs to take based on the direction of train travel.

Line maps are arranged on a strict grid using consistent spac-ing between stations with station names, in Tamil and English only, always arranged alternatively left and right of the line of travel. The current station name is always shown highlighted with a band and an arrow indicating the direction of the train.

The header of the map shows the platform number and the end station name. This end station name helps in relating to the map after selecting the direction of travel after taking ref-erence of dynamic information on the PIDS.

Stations passed behind are shown on line maps with a very light grey colour. This helps in focusing users attention to the stations ahead on the journey and also making him aware of other stations already passed. The interchanges with MRTS, Suburban systems and bus ter-minals are also shown prominently.

Digital templates for line map layout, colours and details ac-company this manual in separate folders on the disk version.

These same line maps can be used on platforms in case they are not combined with the station name.
