There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and...

NSF Collaborative Research: RAPID: Maintain Mobility and Reduce Infection Through a Resilient Transit and Micromobility System
John MacArthur
The COVID-19 pandemic has caused unprecedented disruptions to health, the economy, and transportation systems in cities. The key strategy to combat growth in the infection rate is through "social distancing," maintaining physical separation from others. This strategy is incompatible with transit systems and ridership in nearly every transit market has plunged, causing agencies to reduce service levels to protect riders and employees. Still, mobility is required in many cities and the ability ...
