Drawing Striping

• Associate “pattern” to the striping components.• Define reference element. This can be the baseline

chain or any feature that the stripe is parallel to.• If the “reference” element is in a reference, then

selection set must be used.• Stop bars, cross walks, and pavement messages are

drawn using other tools.

Solid Striping• Select the pay item and click on Draw

Striping. Hint: Start with solid stripes they can be referenced for the skip striping.

• Define the reference element. If possible use a chain.

• The Begin and End points will populate from the selected element. To modify click on the begin or end distance button then data point where the stripe begins or ends.

• Define the offset and click on Draw Stripes.

Drawing Separation Striping• Select the item and define the distance

between stripes, angle and tolerance. Set the stripe angle as Fixed or Variable. Fixed stripes are parallel to the first stripe, relative to the Reference Point. Variable stripes maintain the angle of the stripe between the stripe & the location side.

• Use the solid stripe as side references. • Identify the sides. Side 1, the line the

stripe is drawn from and side 2, the line the stripe is drawn toward.

• Click on Draw Separation.

Drawing Diverging Gore Markings• Select the item.• Define the distance between

chevrons and the tolerance.• Set the Gore and Diverge points.• Set the breaking line. Note: this point

is important as the lines are 45 degrees from this reference.

• Identify the sides. The order doesn’t matter. However the software begins on side 2.

• Click on Draw Chevron Diverge.

Drawing Island Markings

• This requires the use of both the Chevron Diverge and Chevron Merge dialogs.

• Begin with drawing the diverging section. Note: this may require some minor cleanup of lines and drawing temporary lines.

• Using the side of the island and the top chevron, identify the area for merging chevrons.

• Again this may require minor cleanup and the creation of temporary lines.

Pavement Messages and Arrows• Click on the Location tab.• The element can be a DGN element or a chain.

Usually it will be a lane line.• When defining the element, data point on the

element once to select it and a second time near a endpoint to define “Begin” point of the element.

Define the “method” by which the cells will be spaced. This can be set to increments, maximum spacing, etc. Define the rotation Angle & Justification. Distances are based on the justification.

Raised Pavement Markers

• RPM’s do not have to be shown, they can be calculated using adhoc attributes on the paint, but it is much easier to verify quantities if they are shown.

• If they are drawn, use Draw cell group with the spacing “method” as increment

Placing Sign Assemblies

• This program automates the placement of the sign cells and all applicable labels.

• Before using the program the user needs to set the preferences. These are then saved in a resource file.

Draw Sign – Panel Properties • Since “signs” are usually a grouping of

several items, the application is based on the idea of an “assembly”.

• After selecting the sign panel, set the size and the state of the assembly.

“Is Main Panel” must be toggled on for all panels that define the total width. Panels that have “Exclude Area” toggled on are not included in the area calculation. Define the Plot Scale.

Draw Sign – Panel Location• Set the location as either by Origin or Along Element.

The Element can be a chain or DGN element. The Station & Offset can be set. The rotation is set via Dynamic, 2 point, absolute or relative.

• Set the label prefs.

Click on Place Sign Panel then data point to define the location. If the sign panel label is toggled on, it will prompt to place the labels. Note: labels can be placed at anytime.

Draw Sign – Post Properties• After placing the panels

the support can be placed from the Post Properties tab. Select the installation method, state, mounting and sign type if applicable.

Click on the Identify existing sign assembly icon, and select the sign panel. Then click on the Auto-Select button. The program will use the information stored on the sign panels and the installation information set on this tab to calculate the support and pay item information.

Draw Sign – Misc. Features• Copy sign assembly by selection set allows

the user to select a sign group that has already been placed in the file and use it at a new location without re-entering the information.

• Update Sign Panel allows the user to change sign panel fields or sizes without redrawing all of the information.

• Update assembly will update the entire sign assembly including panel and post properties.

Special Signs

• Design special signs using GuidSign, or by some other method.

• The sign can then be placed in plan view from the DrawSign program or by grouping the sign detail in the Guide Sign Worksheet and placing it in the plan sheet as a no name cell.

• Tag attributes manually.

Miscellaneous Traffic Plan Items• The creation of many Traffic

Plan items such as Signalization and Lighting elements consists mostly in placing cells, linear elements and labels. This is easily facilitated through the D&C Manager.

• Many of these items are not drawn into a design file, but are computed based on other items. These quantities can be handled by attaching adhocs to the elements that are drawn.

Example: Adding Adhocs to One Item for Multiple Pay Items• Many items, such as

controllers can represent several pay items by attaching additional adhocs to the cell. This is an example of one-to-many for quantities.

Example of Placing Cells• For items that use the same

pay item but could be different cells, a web page or the cell selector dialog could be called by the database in the key-in field. This is an example of many-to-one.

• For example, a key-in such as “mdl l englinks;browser connect;Acbook Influence; browse file sgeng.htm” can be stored in the design key-in field, thus when the item is clicked on in Design Mode the web page is then activated.

Additional Methods for Placing Miscellaneous Traffic Plans Items• This can be done several

ways, through the use of the draw cell by feature application, a VBA or 3PC file. A 3PC file can be an efficient way to automate this task.
