Improvement of Existing Signal Timings and Other Operational Parameter on Selected Signalized Intersection of Rajkot City

As we all know traffic volume is increasing day by day in cities due to growth of industrialization and urbanization of cities. Thus to manage the present traffic volume new methods were adopted to provide better, easy and safe movement of traffic. The traffic conflictions are major on intersections of two roads. Traffic signals is a way to control the traffic at the intersections of the cities and avoid the conflictions of the vehicles at the intersection. Traffic signals also helps the traffic to move with safety and easily, which tends to minimize the collision between the vehicles at the intersection. In this dissertation we surveyed the traffic volume of intersections of the Rajkot city and traffic signals were designed at Nana Mauva intersection. The one part of the thesis is survey of traffic volume, which is done by manual method, wherein the vehicles are counted manually without using any device or sensor with respective vehicle categories like passenger, commercial and agricultural etc. and the other part is design of traffic signals, which is done according to the Webster's method of signal design by adopting maximum PCU on the intersection in each direction. 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. The design of traffic signals at these intersections in Rajkot will help the growing traffic to move with ease and safety and also helps in reducing the accident rate at the intersections due to congestions and confliction between vehicles.
