Technology has been driving the developments in the realm of transportation from the times of Industrial Revolution to the present day Digital Revolution.

TWO MAIN OBJECTIVES: 1. meeting the demand of faster mobility by different modes

2. building capacity and expanding network facilities to accommodate growing traffic needs.

INTRODUCTION:

  Remote Sensing is a Science or a technology and art of obtaining reliable

information about an object, without being physical contact with the object. Ex: human eye

These sensing devices capture the data on the way, various earth surface features emit and reflect the Electro Magnetic Radiation (EMR), and provide information about the resources under investigation

A Geographical Information System is an organized collection of

computer hardware, software, geographic data and personnel designed to efficiently capture ,store, update, manipulate ,analyze and display all forms of geographically referenced information.

 

DEFINITION OF REMOTE SENSING AND GIS:

4

Improve vehicle highway system operation and management techniques

Optimal use of existing infrastructureRemove congestion Coordination of traffic movementsEase driver’s frustrationCheck environmental conditionCheck stress related accidents

 The major MTS application areas can be classified into the following functional groups:

Advanced Public Transport Systems (APTS)Advanced Traffic Management Systems (ATMS)Advanced Traveler Information Systems (ATIS)Electronic Toll Collection and Traffic Management

(ETTM)Commercial vehicle Operations (CVO)

1.ADVANCED TRAFFIC MANAGEMENT SYSTEM (ATMS)

)

The principal users are Passenger, Car Drivers, Pedestrians, Public Transport Passengers, Truck Drivers, and Management Agencies. 

A.EMERGENCY CALL BOXES: Installed at every 2 Km. Pedestal Mounted Protected by Safety Barriers Location Identification at Control

Centre There by providing service

B.VARIABLE MESSAGE SIGNS:

To provide prior information to Users

At Six LocationsMounted on sleek gantriesMessage Signs controlled

and Transmitted from Control Centre

Short and Crisp Messages

 

11

C.TRAFFIC CLASSIFICATION SYSTEM:Provides statistical

Information related to Traffic Flow

Uses Inductive LoopsUsed for Automatic

Classification of Vehicles

Measures Speed and Occupancy Levels

12

D.METEOROLOGICAL INFORMATION SYSTEM:It gives information about

the following factors,Wind SpeedAir TemperatureHumidityVisibilityRoad Temperature for

Road Conditions

13

2.ELECTRONIC TOLL COLLECTION

The principle users are drivers, carriers and highway agencies.

SERVICESAutomatic Toll

Exchange No Stopping of Vehicle No Cash Transaction

14

3.ROUTE GUIDANCE

Route guidance, evacuation guidance, instructions, facility information from the electronic stations, parks etc., can be obtained by the travelers for easy assessment of their destination.

15

GUIDANCE FOR ROUTE PLANNER

16

4.TRAVELLER INFORMATION

17

Danger warning such as vision obscured due to fog, disable car ahead watch out, slow down falling object ahead etc., will be displayed

when the road intersection is closed due to rainfall or due to some other reasons, information such as turn right at next intersection and dedour to National Highway xx will be displayed.

18

In India 70 State Transport Undertakings, which together own and operate 1,13,000 buses and, provide mobility to 65 million passengers a day, across the length and breadth of the country

It has been proved to be the optimal solution to the enigma of building and operating transportation systems to meet expeditiously growing urban travel demand in developed countries.

As per the saying “Prevention is better than Cure”, it is better to prevent Road accidents than providing wide Medical technologies to cure it.
