Signalized intersections are considered as one of the safest type of intersections, however a number of crashes are occurring in these intersections. One of the major causes of these fatal crashes is the presence of amber light di-lemma zone. The main motive of the study is to find out the different factors which influence the driver’s decision making under the influence of amber light dilemma. The study is carried out in Thrissur district of Kerala. Video data was collected from three different intersections for a duration of three hours each-Binary logit model for all vehicle types were prepared in order to determine how the heterogeneous traffic conditions influence the driver behaviour under the influence of amber light dilemma. A combined vehicle model considering all the vehicle types was also developed. The variables which were found to be significantly affecting the driver’s decision making were distance to stop line, approach speed, crossing distance and amber time. Among different vehicle types two-wheelers were found to have a significant influence on driver behaviour. Using the intersection details collected and the vehicular and geometric characteristics obtained from previous approaches the safe crossing distance and safe stopping distance of different vehicle types for different speed ranges were calculated. The insights from this study can be used to enhance the safety and performance of signalized intersections in developing countries.
