Injuries Due to Wedging of Bicycle Wheels in On-road Tram Tracks

BACKGROUND In cities with trams as public transportation, tram tracks are often on public roads, creating a shared road situation with other road participants like cyclists. Beside the risk of direct collisions, this situation can also lead to bicycle wheels getting wedged in tram tracks, causing cyclists to fall. OBJECTIVES The aim of this study was to gain more insight in the injury pattern...

Bicycling crashes on streetcar (tram) or train tracks: mixed methods to identify prevention measures

BACKGROUND Streetcar or train tracks in urban areas are difficult for bicyclists to negotiate and are a cause of crashes and injuries. This study used mixed methods to identify measures to prevent such crashes, by examining track-related crashes that resulted in injuries to cyclists, and obtaining information from the local transit agency and bike shops. METHODS We compared personal, trip, an...

Modeling test rolling on cohesive subgrades

Test rolling is a quality assessment technique performed on road construction materials to verify consistency prior to paving. In this test, the depth to which the wheels of a heavy vehicle penetrate the material is used as a measure of quality. Current test rolling specifications are based largely on empirical data. In this paper, theoretical models are presented for the case of a test roller ...
