Abstract

Increasing motorcycle ownership, especially through its high flexibility and relatively cheap purchasing and operating costs compared to automobiles, increased the share of motorcyclists in traffic accidents. This situation has brought about the need to investigate the factors affecting motorcycle accidents and the prevention to reduce the severity and the number of accidents. In this study, relationships between accident frequency and carriageway hazard, road type, and surface condition were examined using the data set of motorcycle accidents that occurred in England. Vehicle load, object, animal, pedestrian, and previous accident on road were considered as carriageway hazards, one-way street, roundabout, slip road, single and dual carriageway were considered as road types, and wet and dry indicates the road surface conditions. Thus, accident frequencies were estimated using log-linear analysis, and the measures to be taken were discussed.
