Advanced Traveller Information System (ATIS) is one of the important sub-systems of Intelligent Transportation System (ITS) designed to provide real time traffic information to drivers, especially in cases of incidents. The Kallang/Paya Lebar Expressway (KPE) in Singapore is a predominantly underground expressway under construction at the time this study was earned out. KPE creates unique challenges for the prevention of incidents such as congestion, accidents and fire. Comprehensive message broadcasting schemes are to be introduced to broadcast traffic information via ATIS to provide advisory and warning information in cases of congestion, accidents, and emergency evacuation. However, knowledge on how drivers would respond to those schemes still remains insufficient. Such knowledge is essential, not only to line-tune the schemes in KPE, but also for design and operation of similar ATIS systems in general.
