This paper describes a research project that studies drivers’ route choice behaviour in response to the content of Variable Message Signs (VMS). In particular, the influencing factors for drivers are investigated including: types of incidents, degree of congestion, status of congestion and location of an incident. Verification of drivers’ perception about some qualitative delay time information is also examined. A Stated Preference survey by questionnaire was conducted with residents along a target route in Adelaide. Binary logit models were developed for drivers’ route choice preference and other significant factors such as: socio-economic factors, familiarity with the road network and experience of VMS. The results indicate that the content of VMS influences route choice behaviour. In particular, the degree of delay, status of congestion and location of incident are significant factors influencing the probability of diversion. Results also indicate that differing characteristics and the experience of each driver influences route choice behaviour.
