This report presents new tools created to assess bicycle suitability using geographic information systems (GIS). Bicycle suitability is a rating of how appropriate a roadway is for bicycle travel based on attributes of the roadway, such as vehicle volumes, shoulder width, and bike lane width. The new GIS tools are based on the Bicycle Level-of-Service method in the 2010 Highway Capacity Manual (HCM). The Idaho Transportation Department (ITD) can use the new tools to assess state highways when conducting corridor planning. The tools can be used to prioritize improvement strategies, such as wider bike lanes or new shared-use paths. Local planners, perhaps working with ITD, can use the tools to evaluate the bikeability of their community, i.e. the ability to access important destinations by bicycle. Example output is provided for three case study communities. |
