At signalized intersections apart from cycle length and phase, the change and clearance interval play significant role with respect to safety and free movement of vehicle. It involves the dilemma zone characteristics at change and lost timings. The vehicle behavior in dilemma zone during change intervals is the decisive factor for uninterrupted safe movement of vehicle. Driving behavior differs in homogeneous and heterogeneous traffic. Most of the studies in the literature have investigated the dilemma zone driving behavior in homogeneous traffic conditions, but traffic in developing countries like India is heterogeneous containing various vehicle types, where vehicles vary in their physical dimensions and dynamic characteristics. The main objective of this paper is to empirically investigate driver’s decision zone at flashing green and yellow indication at high-speed intersections. The driving behavior survey for heterogeneous traffic at a signalized intersection shall be carried out by videography. Data analysis will be based on the speed-distance diagram (S-D diagram) and an acceleration-deceleration diagram (A-D diagram). The behavior will be analyzed with respect to both qualitative and quantitative aspects to arrive at conclusions regarding measures for improvement for better safety. This is a literature review-based paper that aims at studying various researches already done in the field and drawing conclusions thereon.
