Abstract

Cyclists are vulnerable road users in traffic accidents. The safety problem caused by risky behavior of cyclists is severe. This study is intended to understand cyclists' risky route choice behavior on road sections from the view point of safety. Stated Preference survey is adopted to investigate the cyclist' route choice on fixed origin and destination points. Three alternative routes are available: riding conforming to rules, crossing at midblock without zebra crossings, and riding in the wrong direction. A novel virtual simulation method is adopted in choice scenarios to improve presentation of the attributes of road sections and traffic conditions. Random parameter models are estimated to find out how individual characteristics, bicycle types, trip attributes and built environment will influence cyclists' safety perception and risky behavior. The trade-offs between safety perception and travel distance are estimated in route choice model. In safety perception model, the significant attributes differ within three routes: respondents mainly pay attention to the number of motor lanes, motor volume when crossing the road; while for riding in the wrong direction, distance of wrong way and separation type are more considerable factors.
