محاكاة حركة المرور و نظام العمل الامثلي على التقاطعات الطرقية غير المضبوطة باشارة ضوئية

This research describes a simulation model to simulate the traffic flow at Unsignalized intersections and determine their optimal function using simulation and queuing theory technique. All that intends to determine the critical traffic flows and delays at the intersections and its approaches. In order to implement the suggested traffic and road solutions or modify them, the parameters mentioned above are considered the main criteria that determine the level of service with respect to evaluating the actual traffic and road conditions. All parameters has been obtained from field observations at many intersections in Damascus and Lattakia. Model validity has been conducted by comparing simulated results to field observations.
