Separated bike lanes have become increasingly common around the United States as cities seek to attract the new riders, including people who want to ride but limit their riding because they do not feel comfortable riding with motor vehicle traffic. Planners and engineers are working to identify contextually appropriate, safe, and comfortable designs for intersection locations, where bicyclist paths cross the paths of turning vehicles as well as cross-traffic. This research employed a combination of user surveys and simulations to anticipate expected bicyclist and turning vehicle interactions and bicyclist comfort based on design type and volumes. Findings examine which types of intersection designs, ranging from protected intersection and bike signals to mixing zones, are most comfortable for a range of cyclists, while taking into account expected motor vehicle traffic. This project will provide valuable information to cities as they seek to include comfort-based factors into design selection criteria – an endeavor that may be essential to attracting the coveted Interested but Concerned riders.
Dr. Christopher M. Monsere is Professor and Chair of Civil and Environmental Engineering in the Maseeh College of Engineering & Computer Science at Portland State University. Dr. Monsere's primary research interests are in design and operation of multimodal transportation facilities including user behavior, comprehension, preferences, and the overall safety effectiveness of transportation improvements. Dr Monsere is a member of ANF20, the Bicycle Transportation Committee, the past co-chair of the Transportation Research Board's Safety Data, Analysis, and Evaluation committee (ANB20) and a past member of the TRB Task Force to develop the Highway Safety Manual (ANB25T). Monsere received his BCE from the University of Detroit Mercy; his MSCE and Ph.D.with an emphasis in transportation from Iowa State University. Dr. Monsere is licensed professional engineer in the state of Oregon.
Nathan McNeil is a research associate at the Center for Urban Studies at Portland State University. He conducts research around impacts of new bicycle infrastructure and programs on travel behavior and attitudes towards cycling, shared-use mobility programs including carsharing and bike-share, and the connection between land-use and transportation. Nathan received a Master of Urban and Regional Planning from Portland State University, and studied history at Columbia University as an undergraduate. Prior to PSU, McNeil worked for the Metropolitan Transportation Authority (MTA) in New York City as a performance auditor where he evaluated capital programs and contractors.
