Abstract: A mapping system tailors maps and directions for bicyclists. The mapping system stores map data including data about the suitability for biking along roads in a road network. A cost model, including a turn model, a hill model, and a penalty/bonus model is applied to the road network. The turn model models how long it takes to traverse an intersection.
