Introduction
Present Traffic Scenario:-
1. Rail- 48% , Bus- 44% & Private Vehicles - 8%.
2. Inadequate road network.
3. Suburban rail traffic increased by 6 times while the capacity increased by
only 2.3 times.
4. 4500 passengers travel per train against the carrying capacity of 1750 resulting
an unbearable overcrowding
5. Vehicular growth Increased from 61,000 to over 1.02 Million in the last four
decades.
N E E D
Existing suburban systems under extreme pressure Existing bus system’s role limited to providing feeder services to
railways. Bus system alone cannot meet the future demand Constraints to expand the existing road network capacity The Road & Rail improvements not adequate for future demand Many pockets in Island city and suburbs not served by rail based
mass system. Environmental deterioration due to growth in road traffic
W H Y
• it has high-capacity • ...it is fast • ...it is environment-friendly • ...it is financially viable and economical • ...and is attractive to the commuters
A D V A N T A G E S
Carries same amount of traffic as 6 lane bus or 26 lane Private cars (Either way).
Reliable, Comfortable and Safe Reduces time by 50-75% as compared to road No Air pollution and less noise levels Energy efficient; Consumes 1/5th Energy per road
passenger km. Occupies no road space if underground and only about 2m
width of road if elevated
