Another option to consider: Valhalla, the only open-source routing engine that can plan multimodal journeys (car, transit, walk, cycle) around the world. It can, for example, plan a journey on foot, rail, and bus that crosses multiple metro regions. - all code at https://github.com/valhalla https://github.com/valhalla - also available as a hosted service for free at https://mapzen.com/projects/turn-by-turn/ https://mapzen.com/projects/turn-by-turn/ (N.B. I'm employed by Mapzen.) You can also try out Mapzen's routing service along with many others, like OSRM and GraphHopper, on the OpenStreetMap site. For example: http://www.openstreetmap.org/directions?engine=mapzen_bicycle&route=37.3767%2C-122.0581%3B37.2456%2C-122.4076#map=11/37.3082/-122.2325 http://www.openstreetmap.org/directions?engine=mapzen_bicycl... Each routing engine has its strengths and weaknesses. Great that all share their code as open-source.
