Identify Traffic Congestion Using Speed Data Measured By Gis, Gps Technique

With the rapid vehicle volume growth on roads, the performance of urban road traffic systems is a major concern to transportation planners, road users, and all members of the urban community. The evaluation of the performance measures relies on the accuracy and reliability of the collected traffic data. This study investigates traffic speed measurement using GPS technique for parts of Al-Karada Khareeg road by identify the congested segments. The collected GPS points were mapped to the highway using Arc Map 10 program in a GIS environment. Travel time, speed and congestion index values were measured along selected highway segments for evaluating the traffic condition of the highways. The benefit of this way is simple, and easy to understand
