In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where.
Traditional bicycle counters can provide data for limited sections of the bike network, often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only rep...

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...
