Dilemma-free control is a method of controlling traffic signals to minimize the situations when drivers are caught in the dilemma zone. One important aspect of dilemma-free control is the understanding of drivers behavior involving the reaction time to take braking actions and the decelerationrate of a vehicle. However, there is a lack of empirical research on thiscritical issue. This paper describes a study to extract the factors affecting the drivers decision to stop or to pass an intersection in the dilemma zone using a driving simulator (DS). Results of this study show that the drivers decision depends on the vehicle's distance to the stop line, road surface conditions and indication of pedestrian traffic lights. It is found that there is no clear difference in vehicle approach speeds between those that stop for the signal and those that do not stop.
