Travel Time Accessibility

See how far and how quickly you can travel from anywhere in your system using travel time isochrones. Foursquare ITP’s tool combines GTFS schedule data and open source street network information to generate transit travel time isochrones at any time period or location. The results are a valuable aid in evaluating accessibility from key points of interest or transit stations. Foursquare ITP can deploy web applications allowing for interactive isochrone generation, export geometry for use in your agency’s GIS programs, or analyze this data for a planning study. Foursquare ITP staff use this tool to assess transit network changes and evaluate our transit service planning proposals.

Example Application: For the New Orleans Comprehensive Operational Analysis, Foursquare ITP identified travel times on transit from key locations in the city to identify opportunities to provide faster services.
