Abstract

Intersections are one of the most crucial parts of urban transportation systems since they actively contribute to developing strategies to reduce traffic congestion. Congestion is one of the major issues that intersections face as a result of the growth in traffic, which cause lower service levels and longer waiting time. The main goal of this study was to evaluate the current traffic flow and Level of Service (LoS) at four signalized intersections at peak hours in the city of Al-Bayda utilizing sidra software. In addition, comparing the performance of traffic flow during the morning and evening peak hours at the selected intersections. The results revealed that the level of service of the four intersections was very low and ranged between F and D, which indicated that the delay time was very high, therefore, an improvement to these intersections was necessary. After exploring various alternatives, the level of service increased to B and D levels, which make the delay time acceptable in these intersections. In the morning period, the average delay time decreased by 43.6, 44.3, 32.3, and 42% for intersections no.1-4 respectively. In the evening period, the average delay time decreased by 45.8, 69.5, 57.5, and 52% for intersections no.1-4 respectively.
