  1. PUBLIC TRANSPORT ACCESS & RIDERSHIP:A CLEAN AIR ISSUE Geetam Tiwari Transportation Research and Injury prevention Programme Indian Institute of Technology Delhi BAQ, Jogjakarta, 13-16 December 2006

  2. Optimality Indicators of Transport System • Least space consumption/passenger-km • Least energy consumption/ passenger- km • Least emission/passenger-km • Least accidents/passenger-km

  3. Comparison of Optimality Indicators Fatalitiy does not include access trips. Public transport- Bus and Train/metro to be given priority

  4. Priorities for optimal modal mix • Preserving walking and bicycle trips in all cities • Mixed Landuse, • relationship between informal and formal sector • City speed limits 50km/h • Safe infrastructure • PT for serving 5-15kms long trips (30-40%) of total trips • Safe walking and bicycling • Medium density to generate sufficient demand • Fares to compete with MTW operating cost

  5. System Summary

  6. TRIP LENGTH DISTRIBUTION IN SELECTED CITIES > 85% trips are less than 10 km long

  7. Desirable trip length for userspreferred choice Distance, time, access/line haul, marginal cost, safety, security 2WH: 1.8 3WH: 2.5 Car: 4.8 Taxi: 7 Bus: 6.5 Metro: 14

  8. Issues for Public Transport • MTW and car trips < 10kms have to be served by PT • Marginal cost of using a MTW ~ Rs.60/km • ~ 75% of the registers vehicles are MTWs • Every PT trip is also a walking/bicycle trip Catchment area of Public transport, construction time and cost should influence the choiceof technology.

  9. 200 metro users and 200 bus users survey, Delhi 2005 • Average number of transfers of metro users> bus users • Number of transfers increase with increase in journey distance

  10. Comparison of Bus users (BU) and Metro users (MU), Delhi 2005 • Access+Egress Distance ~4 Km(BU) 8 Km(MU) • % of Total Distance 15 45 • Access + Egress Time 17 mn32mn • % of Total Time 27 67 • Average no. of Transfers 3.53 3,81 • Cost short distance 4 Rs 8 Rs Long distance .20Rs .60Rs Bus has higher accessibility than metro

  11. Conclusion • Bus system is more accessible (distance, time, cost) • Journey times for short trips are comparable to Metro (despite mixed traffic) • Load factor is close to one • Improved infrastructure will attract MTW users

  12. PLANNING FOR SUSTAINABLE URBAN TRANSPORT • Promotion of public transport only possible if pedestrians and bicyclists are safer • Designs of bus stands and vehicles for safe entry and exit • Role of street hawkers and vendors to be integrated in road design • Provision of segregated bicycle lanes on all arterial roads otherwise bus operation inefficient • Convenient bus stop locations
