Want to learn more about bicycle safety? PhD student Nicholas Fournier of UMass Amherst talks about his two research studies currently being conducted at UMass. Mr. Fournier is studying for a PhD in transportation engineering and an MS in regional planning at the University of Massachusetts, Amherst. View Mr. Fournier discussing his research at this link. One of the highlighted studies used the UMass advanced driving simulator to test how well drivers approaching intersections understand different on-road bicycle infrastructure, such as bike boxes and merged bike lanes, which are designed to reduce left-hook bicyclist-motor vehicle crashes and promote bicyclist safety. In the second study, Mr. Fournier developed a sine-wave model for estimating annual on-road bicycle travel demand in cities where bicycle demand can fluctuate considerably across seasons. The model reduces the number of sample counts needed to develop an estimate for bicycle demand, making it easier for researchers and practitioners in a city to measure bicycle ridership and the overall safety of their road infrastructure for bicyclists.
