~ 1970 Downward trend success ~ vehicle safety(cars), access control highways(vehicle safety) Marginal decline since 1990(more people inside cars) Downward trends in road traffic fatalities  in high-income countries  not reducing since 1990s
VRUs are RTC victims in all countries, higher proportion in low income countries; NMVs, PT dominant modes “ success” ~ more people travel by car  Netherlands:high bicycle use and RTC victims Thailand & Malaysia: High MTW and RTC victims Source: Various WHO collaborators in countries 0% 20% 40% 60% 80% 100% USA Thailand Colombo, Sri Lanka South Africa Netherlands Malaysia Kenya Japan Bandung, Indonesia Delhi, India Ghana Australia Pedestrians Bicyclists Motorized 2-wheelers Motorized 4-wheelers Other
Victims in URBAN RTC Highest share of RTC fatalities in urban areas are pedestrians regardless of country income; eg New York 54%  London 30% Johannesburg  33% Mexico city  52% Delhi  50% Mumbai  75% Tehran  33% Shanghai 40% Urban problem, not of development! ‘ Safe countries’ have achieved peds safety on highways, not in cities
China Vision of global city, progress,  success 1991-1996 i nfrastructure investment $10billion Average speed 15Km/h !! , NMV trips 25% from 40%,  increased travel distances & RTCs peds~40%
80/m FTRC, ~5000 70/m, FTRC 4500 50/m, FTRC ~8000 Fatalities in Indian Cities(~ 18000/year),  higher rates in metro cities
Pedestrian and cyclists have highest risk in the safest city! Trip types and fatality rates in central Copenhagen IIT Delhi 2005
Urban Mobility PT and NMV based, MTW majority personal  vehicles
Urban Transport India:2040 ~40% urbanization; 600-680 m people ~USD 15000 per capita urban income Car ownership: 100-150/1000 persons Small cars Public transport Vehicle ownership: 300-500/1000 persons MTW Small cars Buses ~90m cars ;  270m vehicles
Priorities for Energy Efficient/Low EmissionUrban Transport Preserving walking and bicycle trips in all cities(20-60%) Mixed Landuse (short trips)  relationship between informal and formal sector (captive users) City speed limits < 50km/h( safety considerations) Safe infrastructure (network connectivity)
Priorities for Energy Efficient/low emission Urban Transport PT for serving 5-15km trips (30-40%) of total trips Safe walking and bicycling(feeder modes) Medium density to generate sufficient demand Fares to compete with MTW operating cost
Existing scenario …. Chaos at bus shelters Bus stops in the middle of the road; commuters don’t use bus shelters Commuters cross six lanes to access bus shelters
Pedestrian safety The most influential factor ..in making a decision to cross at a designated crossing location is the distance of the crosswalk to desired destinations of pedestrians. (Handy, 1996; Shriver, 1997 )  Besides, improvements in safety and comfort for pedestrians can be obtained without major side effects on vehicle travel (Carsten et al., 1998).  Also it is evident that pedestrian safety can be affected by changes in the signal settings at signalized crosswalks(peds delay< 40 sec) (Garter, 1989).
Mixed Traffic  NMV & PT friendly
PT and NMV facilities at intersection Fence on three sides of the bus stops to prevent jay walking
Pedestrian Bridge ~ 6-8 m high increases walking distance by 100-200 m Discourages use of Public transport  More motorcycles and cars leading to congestion and high risk in off peak hours
Bicycle lane and Midblock bus shelter   (single platform) ~1500 bicycles/h At grade pedestrian crossing
