【 摘 要 】

Baghdad city, the capital of Iraq has mainly suffered from influences of transportation highway modes especially at intersections. Traffic management system TMS leads to improve the level of service LOS of the intersections by reducing traffic congestion, delay and time wasted during travel. This research studied the improving of TMS for deactivated Al-Faris Al-Arabi signalized roundabout that considered the important area near city center. Traffic data collected manually by group of engineers during March and April, 2018. Highway Capacity Software HCS2010 used to assess and improve the TMS for current and future forecasted flow. Results showed that roundabout operating on LOS F with a high delay of time and saturation flow. Three solutions proposed to improve the traffic conditions considering of modifying the geometric features with changing and optimizing the timing plan of traffic signals. It showed a highly improving in LOS from F to B, improving saturation flow to less than one and reducing in delay time to about 43 times of that at existing conditions. In addition to analysis results, 18 years has been expected to carry the future forecasted data. Finally, architectural model has been achieved to display the pre and post improvement of the study area.
