Road vehicles, especially two wheelers have substantially increased.

Whereas the infrastructure facilities of the city not proportionately increased.

Due to increase in vehicle population, the average journey time has increased

Growth of Vehicle Population

3%

▄Chennai is the fourth- largest city in India with a population of about 8 million

▄11 million trips in a day, of which about 6 million vehicular trip

▄Many areas in city and suburbs are not served by rail based system

▄Suburban and MRTS traffic have increased, but NOT in tune with the traffic

demand

▄Rail network expansion failed to keep pace with demand resulting in severe

congestion on road network & Environmental pollution

Present Scenario of Transport Infrastructure

12

26% 71%

13

The options are…………

1. ROAD BASED SYSTEM

2. RAIL BASED MASS TRANSIT SYSTEM

14

ROAD BASED SYSTEM

Widening of Roads Involves large scale land and building acquisition in the heart of the City- not feasible

Elevated Bus bay systemDedicated bus bays/expressways not feasible because: -numerous existing flyovers ;

-city landscape intervened with commercial/residential buildings and walkways

15

RAIL BASED MASS TRANSIT SYSTEM

Mono Rail: Suitable as a feeder serviceLimited capacity <10000 phpdt

Light Rail Transit (LRT): Suitable for low to medium capacity trafficbetween 10000 and 25000 phpdt

The arterial roads of Chennai is already having traffic in the order of 30000phpdt and growing steadily

16

RAIL BASED MASS TRANSIT SYSTEM

Medium Capacity Metro System

Suitable for traffic demand of 30000-40000 phpdt

Most economically suited system for the saturated corridors of the Chennai City

17

Advantages of Metro System Requires 1/5th energy per passenger km compared to road

based system

More reliable, Comfortable and Safer

Fully air conditioned

Carries same amount of traffic as 7 lanes of bus traffic or 22 lanes of private cars

Reduces journey time by 50 to75%

Washermanpet to Airport

-by road will take 90 to 100 minutes

-Metro Rail will take 45 minutes

18

Advantages of Metro System

Tangible & non Tangible SavingsSocio Economic Benefits

Vehicle operating costs (VOC) savedPassenger time savedLess air and noise pollutionReduction in number of road accidentsReduction in Road infrastructure and consequent

maintenanceChennai city will be placed in global Metro map

CHENNAI METRO SELECTION OF CORRIDOR

Detailed Feasibility Study was carried out, and 7 (Seven) corridors prioritised

Detailed traffic survey was done for the

Govt. decided to take up Corridor 1 & Corridor 2, under Phase-I based on maximum ridership

Subsequently both these corridors slightly modified-extent reduced.

Corridor 3 will be taken up under Phase-II Extension of Corridor 1 (to Tiruvottiyur) will be taken

up shortly
