TRAFFICE SIGNAL DESIGN AND CO-ORDINATION BETWEEN TWO INTERSECTIONS OF DHANSURA-SHAMLAJI ROAD-A CASE STUDY OF MODASA CITY

There are two objectives for this research. One is to develop an effective procedure to optimize intersection signal timing by minimizing total delay for both vehicles and pedestrians. The second objective is to establish guidance for pedestrian crossing phase selection and the length of WALK phase when scramble crossing is used. An optimization procedure for signal plans on intersections is developed. The object of this report is to give traffic engineers or technicians in the cities of the emerging world a brief introduction to traffic signals, together with some practical guidelines on how to use them to obtain good and safe results. The lack of traffic signal conspicuity is often cited as a contributing factor by drivers who are involved in accidents at intersections. As such, increasing the conspicuity of traffic signals should lead to improved safety performance. This paper describes a project to determine the road safety effectiveness associated with improved signal design and better co-ordination between two intersections. A time-series evaluation was completed to investigate the effectiveness of the improvements to the traffic signal on road safety performance. Anecdotal information concerning the effectiveness of the improved traffic signals were also collected and evaluated.
