Heterogeneous traffic, Optimizing signal time, Saturation flow rate

Intersections are one of the most critical elements that affect the performance of urban road network. For safe and efficient movement of large volumes of traffic on city road network. Saturation flows, lost times and Passenger Car Units (PCU) are the significant parameters in the planning, design and control of signalized intersection. The accurate estimation of saturation flow values is prime importance when determining the capacity of signalized intersection. KKV intersection is one of major intersection of Rajkot city. Considering the saturation flow at KKV intersection, optimization of signal timing was done. In present scenario, cycle length of KKV intersection is 250seconds, so that signal delay at all approaches is more than 170seconds. These problems can be overcome with signal optimization. It is done with three phases and four phases and found that cycle length is decrease as 157 sec as well as delay is also decreasing at all approaches.
