PBR (Personal Bike Routing) is a free app that helps riders with ios phones to find safer, quieter routes in Chicago and NYC. The app was developed by a team of volunteers at chihacknight.org using open source code. PBR is for riders who are looking for more pleasant routes, using mostly residential streets, to get from point A to B. The two screen shots below compare PBR route (top) and Google Maps (below); the routes are the same distance but PBR uses Francisco (quieter) rather than California (busier). The team is looking for feedback and hopes to build out more features like turn-by-turn directions and locations of Divvy stations.
