Traffic Signal Design and Its Coordination

Abstract

Transportation should be safe, rapid, comfortable, convenient, economical and ecofriendly. But transportation also consumes a lot of resources like time. Traffic management plays a vital role in the field of transportation engineering to reduce congestion and travel time to improve service volumes especially in urban areas. Present road stretch is of length 2.5Km, from kothi char rasta to lalbaugh bridge with four crossings and. In the present study an effort is made to understand and evaluate the performance of the study road stretch. After traffic engineering survey, optimum cycle length and saturation flows, green time signal phase are designed and likewise red, amber phases based on Websters method & IRC guidelines. In this road stretch, adjacent signals are coordinated and the coordinated signal time plans are also developed. This paper solves the traffic congestion causing delays, decrease the travel time and increases the travel speed of vehicles by design of coordinated traffic signals and gives the management measures to reduce the traffic congestion which is of low cost and easily executable.
