Abstract

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.
