Abstract
The road transportation increases year by year, but the rate of road crashes also increases with it. India is one of the developing countries, where the rate of road crashes is more than the critical limit. According to manual count with 15-minute intervals could be used to obtain the traffic volume data. The collected data is converted into PCU units. The synchronization of traffic light systems is one of the best solutions in order to avoid problematic traffic jams. One of the common causes of traffic jams is because of non-synchronized traffic light systems. Once a light turns green, traffic begins to move, but by the time the moving traffic reaches the next light, the signal is still red. This will disrupt the continuity of the traffic flow, especially for large main roads. The smooth flow of traffic on main routes is important to clear dense traffic in a given time. Webster’s method is a rational approach for signal design. The design is simple and is totally based on formulae’s laid down by Webster. In this method, the total cycle of the signal is determined which forms a total least delay occurring at signal. The outcomes of this study support the hypothesis that retiming traffic lights to create a synchronized traffic light system for main roads will greatly improve traffic flow.
