I’m working on a transportation model, and am about to do a travel time

  • 0

I’m working on a transportation model, and am about to do a travel time matrix between 5,000 points. Is there a free, semi-reliable way to calculate the travel times between all my nodes?

I think google maps has a limit on the number of queries / hits I can achieve.

EDIT

I’d like to use an api such as google maps or similar ones as they include data such as road directions, number of lanes, posted speed, type of road, etc …

EDIT 2

Please be advised that openstreet map data is incomplete and not available for all jurisdictions outside the US

    Google Directions API restricts you to 2500 calls per day. Additionally, terms of service stipulate that you must only use the service “in conjunction with displaying the results on a Google map”.

    You may be interested in OpenTripPlanner, an in-development project which can do multi-modal routing, and Graphserver on which OpenTripPlanner is built.

    One approach would be to use OpenStreetMap data with Graphserver to generate Shortest Path Trees from each node.
