Abstract: An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The experiment collected information on drivers' pre-trip route choice behavior at three levels of information accuracy, 60 percent, 75 percent and 90 percent. An analysis of variance was performed on the data to investigate the interrelationships among the different variables in an attempt to develop an understanding of what factors significantly influence route choice behavior and learning. An attempt was made to model sequential route choice behavior using a binary logic model formulation with mixed results. It was assumed that drivers update their knowledge of the system based on their previous experiences and therefore an information updating function was specified and incorporated into the model.
