Job-Worker Balance & Polycentric Transit-Oriented Development: Toward Indices and Spatio-temporal Trends

Robert Hibberd
According to new research, transit-oriented development (TOD) can address the equity challenge of "spatial mismatch," where urban residents are isolated from relevant employment centers, and significantly improve employment access. "Job-Worker Balance & Polycentric Transit-Oriented Development: Toward Indices and Spatio-temporal Trends," funded by the National Institute for Transportation and Communities (NITC), examines how transit-oriented development (TOD) affects employment access and… Read More

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… Read More
