New Tools and Technologies to Assess Public Transport Network and
Accessibility
October 8, 2015Istanbul
Dr. Jen JungEun OhSenior Transport Economist, World Bank
World Bank in the last 15 years…
• Financed 70+ urban transport projects, in the amount of $12 billion
Latin Amer-ica, the
Caribbean56%
East Asia, Pacific18%
South Asia12%
Africa9%
Middle East, North Africa
3%
Europe, Central Asia1%
– Mass transit systems (metro, BRT, tram)
– System Integration– Non-motorized transport– Traffic management– Leveraged additional
investments of about $8-10 billion (government co-financing, climate financing, private sector)
What technology?
General Transit Feed Specification – GTFS
• Open data standard for digitizing public transport routes– Routes, stops (GIS coordinates), operating schedules, fares– Can be used in any database application or program (.txt file)
OpenStreetMap
• Wikipedia of map – free and editable• Crowd sourcing from data collected by registered users,
using manual survey, GPS devices, aerial photography, etc.• Let’s try!
OK… so what?
We actually used these tools to assess how well public transport
networks works!
Without a penny paid for expensive transport modeling
software
Manila, in 9 months
Kiev, in 2 months
Are the routes duplicated?
How accessible are some locations by PT?
How accessible are some locations by PT?
How accessible are some locations by PT?
You are right,this is not enough…
We need the demand side data to get the full picture
Where people live and work (study, shop, play)?
Which neighborhoods are not served by PT?
What about actual number of people using PT?
• Boarding and alighting survey
GPS-enabled hand-held devices
Smart phone application
that assists data collection
Eager volunteers
Passenger flows on ground transport

Can we improve by re-arranging some routes?
Can we improve by re-arranging some routes?
Larger vehicles making fewer trips Fuel cost & emission savings Direct greater fare revenue to KPT
