    Mumbai traffic scenario & mumbai metro Mumbai traffic scenario & mumbai metro Presentation Transcript

    • MUMBAI METRO RAIL PROJECT .National Institute Of Construction Management And Research
    • CONTENTS Introduction. Project Details. Study Of Tender Documents. Time And Motion Study. Construction And Methodology. Resource Utilization. 2
    • IntroductionPresent 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 overcrowding5. Vehicular growth Increased from 61,000 to over 1.02 Million in the last four decades. 4
    • NEEDExisting suburban systems under extreme pressureExisting bus system’s role limited to providing feeder services torailways.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 basedmass system.Environmental deterioration due to growth in road traffic
    • WHY• it has high-capacity•...it is fast•...it is environment-friendly•...it is financially viable and economical•...and is attractive to the commuters
    • ADVANTAGESCarries same amount of traffic as 6 lane bus or 26 lanePrivate 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 passengerkm.Occupies no road space if underground and only about 2mwidth of road if elevated
    • Mumbai Metro Rail Master Plan:-Phase I (2006 – 2011) Versova-Andheri-Ghatkopar - 11.07Km Colaba-Bandra-Charkop - 38.24Km Bandra-Kurla-Mankhurd - 13.27Km Total - 62.68 KmPhase II (2011 – 2016) Charkop-Dahisar - 7.5Km Ghatkopat-Mulund - 12.4KmPhase III(2016 – 2021) BKC – Kanjur Marg via Airport - 19.5Km Andheri (E)-Dahisar (E) - 18Km Hutatma Chowk-Ghatkopar - 21.8Km Sewri-Prabhadevi - 3.5Km Total Length - 146.5Km 8

    • SIGNIFICANCE (V-A-G)Provides East-West rail based connectivity to Central andWestern suburbs.Facilitates smooth and efficient interchange betweensuburban rail system and MRT System at Andheri andGhatkopar stations.Reduces the journey time from 71 minutes to 21 minutes,between Versova and Ghatkopar .Provides rail based access to the MIDC, SEEPZ andcommercial developments .
