PROJECT PROFILE  

 AUTOMATIC TAXI LOCATION AND DESPATCH SYSTEM

FOR SINGAPORE

CUSTOMER

TIBS Taxis Pte Ltd, Singapore

GENERAL

Singapore Technologies Electronics Limited was

awarded a contract to supply and install a

satellite-based Automated Taxi Location and Despatch

System (ATLDS) for TIBS Taxis Pte. Ltd. In

collaboration with Signalling Technology Pty. Ltd., an

 Australian company, the ATLDS incorporates the best

of GPS (Global Positioning System), CDS

(Computerised Despatch System), IVR (Interactive

Voice Response) and Public Mobile Data Network

(PMDN) technologies.

The implementation of ATLDS is part of TIBS' continualeffort to improve its reliability, efficiency and service

level in the provision of taxis services. The user-friendly

system allows customers to make booking of taxis

through the telephone, PC dial-up, credit card terminal,

palm top and the IVR system. The system locates the

most suitable taxis (based on a number of search

criteria) that is nearest to the pick-up point with the help

of the GPS. The booking details are sent to the driver of

the selected taxis via the PMDN. Once the job is

acknowledged by the driver, the system willautomatically announce to the customer the taxis

number plate and ETA (Expected Time of Arrival)

through the IVR. The whole process, starting with the

customer making a telephone call to the time when a

taxi arrives, is totally automated without the intervention

of an operator or dependent on voice radio calls. Hence,

the time taken to process a booking is greatly reduced

and more customers will be able to get through to the

radio taxis booking line. The frustration of booking a

taxis is a thing of the past.

SYSTEM DESCRIPTION

The ATLDS consists of the following subsystems:

a. Order Taking Subsystem 

The Order Taking Subsystem comprises a PABX andan IVR system. The PABX connects calls and the IVRprovides the interactive response to the caller. ThePABX is incorporated with Telecom's CLI (Call Line

Identification) feature. The CLI feature enables the ATLDS system to identify the caller and at such it isable to retrieve prior information of the caller (such asnames and pick-up addresses) stored in the systemdatabase.

The IVR greets the caller with pre-recordedmessages and prompts the caller at every step toprovide his booking details by pressing of keys on atelephone. With information of the caller alreadystored in the database, the key pressed is translatedas pick-up address to the system.

b. Order Allocation and Despatch Subsystem 

The heart of the system is the Order Allocation andDespatch Subsystem. It performs the intricate task ofprocessing an order, allocating and despatching ataxi to the customer in the shortest time possible.

The system sends out the pick-up address throughthe PMDN network. Vacant taxis within the searchradius of the pick-up address will automaticallyrespond to the system their positions. With theinformation received, the system computes thedistances of the taxis and the taxi nearest to the

pick-up address will then be allocated the job.

c. Information Subsystem 

The Information Subsystem provides a host ofmanagement and accounting information which areuseful for making statistical analysis andmanagement reports.

d. In-Vehicle Equipment 

The In-Vehicle Equipment installed in each taxiconsists of the Mobile Data Terminal (MDT),

Intelligent Interface Unit, PMDN modem and GPSreceiver. The Intelligent Interface Unit provides thein-vehicle processing of information, and itcommunicates with the Order Allocation andDespatch Subsystem via the PMDN modem.

The Mobile Data Terminal provides the display ofmessage containing booking details to the taxi driver.The taxi driver can also communicate with the ControlCentre using pre-canned messages stored in theMDT.

FEATURES •  Improves grade of service and satisfaction to taxi

commuters.

•  Reduces wastage of resources with less emptycruising of taxis.

•  Increases the handling throughput of the ControlCentre as taxis are allocated and dispatched in ashorter time.

•  Eliminates congestion in taxi despatch due to limitedvoice radio channel.

•  Provides driver assistance using big screen displayof road maps in the Control Centre.

•  Provides driver's location at time of distress.

•  Provides valuable information and statistics formanagement analysis and reporting.
