Planning your trip beforehand can help you cut down on your journey time. These services can also provide useful information on distances, calories used, and a rough idea of how quiet or busy your chosen route will be.
CycleStreets uses data from OpenStreetMap, a publicly
available dataset of streets, roads, cut throughways, off road
paths, cycle facilities and bike shops. It recommends direct
or quiet routes dependent on the users needs.
CycleStreets also has a CycleStreets iPhone/BikeRoute Android app.
