what are my travel options?-walk-cycle-vehicle/auto-bus/public transit

Page 3: Crowdsourcing geodata for public transport information

what are my safe travel options?-walk-cycle-vehicle/auto-bus/public transit

Page 4: Crowdsourcing geodata for public transport information

can i travel by bus?

-is there a bus to my destination?-where is the bus stop?-when will my bus come?-how long will my trip take?-how comfortable will it be?-how much will i save?-what are my alternatives?

Page 5: Crowdsourcing geodata for public transport information

who has that information?

-conductors-commuters-bus stations-bus authorities

Page 6: Crowdsourcing geodata for public transport information

how to collect all that data?

Page 7: Crowdsourcing geodata for public transport information

how to collect all that data?crowdsource

Page 8: Crowdsourcing geodata for public transport information

we made busroutes.in

Page 9: Crowdsourcing geodata for public transport information

what we found-crowdsourcing makes data collection faster-errors in of�cial data source-gaps in public transport coverage-patterns in bus route numbers-key transit locations-site analysis data

Page 10: Crowdsourcing geodata for public transport information

how openstreetmap helped-�exible database-crowdsourcing for map data-lets anyone add features-makes the map dynamic-map data entirely opensource

what else we can crowdsource-translate entire dataset into local language-location of each bus stop-addition of other transport links and ways-clean and �x of�cial data-expand database to make it more rich
