unprecedented growth of personal vehicles.Growing traffic congestionAir pollution and traffic accidents has become a

major concern.To avoid congestion at peak hours. Time saving.Reduced fuel consumption

.

Why it is needed

Complement Underground Metro with existing public transportation

No displacement or demolition necessary No Land acquisition and litigation costs Minimal Environmental Impact Address socio-economic need Good Solution, futuristic, fast and cheap Preserve city's culture while being realistic

towards solution

Why it is needed

BENEFITS OF METRO RAIL Requires 1/5th energy per passenger

km compared to road-based transport system. Causes less noise, no air pollution and eco friendly transport system. Occupies no road space if underground and only about 2.60 meters width of the road if elevated. Reduces journey time. Cost effective mass transport system. Reducing traffic transport problems. 5

Air-conditioning and ventilation system for environmental control of stations and tunnels.

Automatic ticket vending and checking system.

Automatic door opening / closing .

A public address system is provided on the trains to announce approaching stations. 6

CONSTRUCTION & METHODOLOGY

Running section is of rectangular twin boxes. Two separate tunnel of 5.4m dia. Separated

centre to centre by two times the dia. Station with side platform or island platform

are housed in rectangular Shield tunneling method is used for 3.8 km 1.5 km by TBM(Delhi main-chawri bazaar) 1 km by NATM method (vishwa vidayalya-old

secretariat)

DESIGN RESOLUTION\MODELLING

FLAC 2D & 3D as primary geotechnical analysis and design tool

Used to determine displacement for use in structural analysis.

Completed in longitudinal & transverse section

Correlated to centrifuge testing to confirm

23SAFETY ACTION

Cut & cover method with continuous diaphragm walls.

Diaphragm walls are constructed in advance using slurry trench method.

Walls are laterally supported by rolled\built up steel section.

Vertical rolled\built up steel section is used to satisfy slenderness limit in diaphragm wall & support traffic as well.

Stretches of 6.6m in dia. With 300mm thick concrete lining.

MUMBAI METRO RAILWAY

The Mumbai Metro Railway System Will Cover A Distance Of 146 Km And Link India’s Financial And Entertainment Capital With Its Suburbs.

The government of the of Maharashtra and the private Reliance Dhirubhai Ambani Group will share the costs of the corridor with the private company picking up 74% of the tab.

A six coach broad gauge train could have carried the same number of passengers as an eight coach standard gauge train.

A six coach broad gauge train could have carried the same number of passengers as an eight coach standard gauge train.

It means lower operational cost, lower electricity cost.

Metro railway system was mooted for the city of Chennai by S Shreedharan the DMRC to the Tamil Nadu CM  Jay Lalitha.

The elevated section of the project is scheduled to be operational by 2011 and the entire project is scheduled to be completed by the financial year 2014-2015.

About 55% of the corridors in Phase I is underground and the remaining elevated.

26

The Metro rail project was included in the 2007-08 State Government's budget, and an amount of Rs. 50 crores had been sanctioned for preliminary works.

The project is estimated to cost around 14,600 crores (approximately USD 3.5 billion) for the two corridors totaling 50.1 km.

The construction started in early 2009 and is expected to be fully completed by 2014.

A total of 34 stations have been planned along the two corridors. As many as 19 stations are underground and 15 are elevated.

27

28

Estimated cost of Rs. 12,132 crores.

The project Hyderabad metro rail is 71.16 km long

PPP Metro Rail Project to have been sanctioned by Govt. of India

Global consulting firm Deloitte is the constructing Co. of HMR.

29

The Metro Rail Project work will start next year and expected to be completed by the end of 2014.

The 71 km covering three high density traffic corridors of Hyderabad. 

Speeds of 34 kmph on an average to 80 kmph maximum.

BANGALORE METRO RAILWAY

The total project outlay envisaged is Rs. 6395 crores.

The project Bangalore metro rail is 42.3 kms long.

The project report of BML is prepared by DMRC.

32

The first face of the project has commenced in 2007 and complete by 2012.

The number of passengers expected to travel on the metro is estimated at 10.20 lakhs in 2012 and 16.10 lakhs in 2021.

Phase I network to about 42 km, with 40 stations.

33

34

Estimated to cost Rs 3,300 crore.

The project Cochin metro rail is 25 kms long.

The starting point of Metro rail in Cochin is in Aluva and the proposed ending point is the place called Pettah.

35

COCHIN METRO RAILWAY

The alignment was created by the DMRC and is planned to be made on a Public-Private Partnership basis. Since it has almost 24 stops between the 25 km, average speed 35kms/hour.

The proposed gauge is standard gauge unlike the broad gauge on the Delhi Metro.

36

37

integrated ticket for bus & metro rail.

Luggage carrying facility should be there.

To encourage people to use Metro there should be a separate parking place for the monthly pass holders.

Concern authority should drop their kind attention to minimize the maintenance cost.

38

Suggestions

CONCLUSION

Although Metro systems are more reliable, comfortable and safer than road based systems & it reduce congestion on the roads. However systems planned in India shows that cost overrunning and under utilization of capacity. Methodology and arguments used to justify these systems needs careful analysis. High capacity system does not necessarily generate high demand. Estimation of passenger demand for transit services should consider complete journey of commuters including access time. 39
