Abstract
Traffic incidents such as traffic accidents are the major causes of severe congestion in urban expressway networks. Providing traffic incident information to travellers is considered to be important for maintaining the level of service in urban expressways. The purpose of this study is to describe drivers’ route choice behaviours when traffic incident information is provided on a Variable Message Sign (VMS) in urban expressway networks. A stated-preference (SP) survey was conducted to observe travellers’ behaviours. The results showed that travellers can assume travel time of their alternative routes according to the congestion information of the road section provided by VMS.
