| Abstract | Increasing traffic volume at intersections has been a source of conflict, road accidents and traffic congestion. Providing of efficient traffic signal control at the intersection can solve these problems and create efficient and continuous movement of traffic. However, traffic congestion usually occurs frequently at downstream of the intersection when two or more movement are exiting the approach at the same time. Moreover, much of the research on signal timing focuses primarily on the entry approach and the exit may be important to the quality of the vehicle's operation at the intersection where the signal is present. Webster and HCM method of determining the signal timing use discharge headway and critical lane value as crucial mechanisms which are suitable for ideal traffic condition. Developing countries with mixed traffic barely follow the lane discipline and the concept of discharge headway cannot be directly applied. In this study, alternative method of determining the separate green time using recently introduced measures, Intersection Throughput Interval (ITI) proposed and compare with delay generated by the conventional HCM’s method by executing simulation program TransModeler. |
