Research Highlights

Bicycle Planning GIS Tool

Joe Broach
Although currently only about one percent of US trips are done by bicycle, there is significant geographic variation. Differences across communities, along with much higher cycling rates observed in other places around the world, indicates large potential bicycling demand for daily travel in the US. In response, many communities are developing and implementing bicycle master plans that include a range of bikeway infrastructure aimed at making riding more appealing, including separated paths, ...

How Technology Can Affect the Demand for Bicycle Transportation: The State of Technology and Projected Applications of Connected Bicycles

John MacArthur
The term “connected vehicle (CV)” refers to vehicles equipped with devices, which enable wireless communication between internal and external entities, supporting vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-everything (V2X) communications. The widespread deployment of CVs will address a range of transportation challenges related to safety, mobility, and sustainability. Recent research efforts on connected bicycles have focused on the uses and limitations of the st... Read More
