Variable Message Signs (VMS) are one of the instruments for providing traveller information, and are considered to be a very effective tool to influence route choice behaviour. The objectives of this research are first, to study drivers' route choice behaviour in response to the content of VMS, with specific reference to what kind of sign content influence drivers' route choice and how many drivers divert their route owing to the VMS information. The second objective is to develop a route choice model for the degree of diversion as a result of the provided information. Questionnaire surveys will be conducted on two target roads, one is an expressway and the other is in the Adelaide CBD. The questionnaire consists of the following items: socio-economic factors, familiarity with the target route, experience of VMS, and a case study. The case study will consist of a field experiment with a VMS sign. Hypothetical VMS messages will be displayed in the case study such as delay time, queue length, cause of delay, and status of congestion.
