The increase in traffic volumes along urban arterial is one of the important problems that makes difficulties in the operation management and movement then leads to traffic congestion in these facilities.
The present paper was dealing with the objectives of evaluation of the level of service along the 17th July arterial in Ramadi city, and use many improvement strategies to overcome the traffic operation problems. To achieve these objectives, the study was comprised of two stages. First stage was related to data collection by field survey where, the arterial street has two unsignalized intersections and traffic volume data were collected manually during 15-minute interval for each intersection of the arterial for both directions WestBound (WB) & EastBound (EB).Second stage included the analysis and evaluation of the arterial street with two cases. In the first case, the arterial was analyzed as street with unsignalized intersections (existing conditions). The arterial street was evaluated by computing its level of service based on the travel time and travel speed data which were measured by license plate method, while in the second case, the arterial was analyzed as street with signalized intersections therefore, Highway Capacity Software 2000 ( HCS 2000 ) program was used to evaluate the level of service for the arterial street. To improve its performance, three scenarios were proposed and applied theoretically. Accordingly, the level of service was improved from E to C for both directions (WB & EB).
