| Abstract | ||
| The concept of capacity and level of service are central to the analysis of intersections, as they are for all types of facilities, however the two concepts are not as strongly correlated as they are for other facility types. It is critical to note at the outset, however that both capacity and level of service must be fully considered to evaluate the overall operation of the intersections. The objectives of the present study include the analysis, evaluation and improvement the operation of selected intersections in the CBD of Baghdad and to present a best proposal to enhance the performance at the required facility. Three congested intersections; Khullani, Wathba and Amin which are located at AL-Jomhoriya Street in the CBD of Baghdad are selected to achieve the objectives of the present study. The required traffic and geometrical data gathered manually and the (O – D) survey technique is used to estimate the distribution of traffic in different directions. SIDRA and TRAFFICQ programs are used for the requirements of traffic analysis process. It has concluded that the proposed improvement for the mentioned intersections is necessary to enhance the capacity and the operation at AL-Jomhoriya Street in CBD of Baghdad. | ||
