The study, using volunteer bicyclists from the Baltimore Bicycling Club, investigated the lateral displacement effects of the presence of a single bicyclist on motor vehicles within the outside lane of a 5 lane urban minor - arterial highway. Observations were performed on three selected highways with 12.5', 13.8' and 17.6' outside lane dimensions. A 4 lane urban minor-arterial highway cross-section that included 4' bike lanes contiguous to the roadway was also studied. The study determined that outside lanes wider than 12' improved bicycle/motor vehicle lane sharing, but that lane widths can be excessive. The bike lane configuration was found to have certain advantages in flow characteristics. Whether the bike lane would be an improvement over simple shoulder construction is unclear. Optimum lane widths can be theorized, but further study is required to form a data base for optimum lane width selection.
