Evaluation and Analysis of Al-Matar Road (Ring Road) In Al- Najaf City

Abstract

Assessing and comprehending the degree of service rendered by diverse transportation infrastructures is of utmost significance for individuals responsible for designing and managing traffic networks. The current study was carried out on the principal urban road named Al-Matar, situated in Al-Najaf City. The methodology involves collecting data regarding the geographic location and implementing traffic surveys, which can include various metrics, including traffic volume, travel time, and free flow speed. The Highway Capacity Manual (HCM) has been designated for evaluating the functional effectiveness of various urban streets. The research findings indicate that the time of travel could be mainly used as an indicator for measuring performance during peak hours or off-peak hours. Additionally, the study observed that U-turns have a significant influence on both travel time and speed. The results indicated the crucial effect of U-turn on the city's operational performance on the ring road.
