Real time traffic control to optimize waiting time of vehicles at a road intersection

Abstract

This paper presents a real time non-linear quadratic programming model to minimize the aggregate delay time of vehicles at each lane by minimizing number of vehicles at each lane at the signalized intersection. One of the most important efficiency and easily getting factors of traffic signal control is the number of vehicles in a queue at the signalized intersection. The initial number of vehicles at each lane at the intersection is counted by camera which is the most accurate method.The model is developed to minimize the number of vehicles from cycle to cycle. This proposed model includes inter green signal time which is one of the key factors compared to other existing models proposed in the past research. This model also incorporates restrictions for upper and lower bounds for green signal time and cycle time allocation which leads to accurate and appropriate allocation for green signal time. The proposed model is solved by the method of sequential quadratic programming coded in MATLAB environment.
