To highlight the biking one:
CycleTracks
CycleTracks, a tool developed by the San Francisco County Transportation Authority, uses your smartphone’s GPS support to record your bicycle trips, display maps of your rides, and help transportation planners make San Francisco a better place to bike. At the end of each trip, real-time data representing the trip purpose, route, and the date and time are sent to the Transportation Authority. Planners use the data to improve the bicycle-use component of their computer model and better predict where cyclists will ride and how land development and transportation infrastructure will affect cycling. Users get to see maps and statistics of their rides.
