Abstract:
This study is a part of a research carried out at Jordan University of Science and Technology for the fulfillment of M.Sc. theses. The main objective of this research was to evaluate the possible and practical traffic management scenarios for reducing traffic congestion in the vicinity of Yarmouk University using traffic simulation. Traffic, geometric and control data were collected from the selected study area which included eight major intersections. The traffic simulation software (CORSIM) was used to test proposed scenarios in two levels: intersection level and network level. The results of the intersection level analysis based on average intersection traffic control delay showed that the two one-way rings scenario was the best alternative for 5 intersections and the second best alternative for 3 intersections. The results of the sub network level analysis showed that the scenario of two rings of one-way streets was the best alternative and provided the highest average sub network speed and the lowest average sub network traffic delay. It was found that little benefit could be obtained by optimizing the traffic signals, while good designed roundabouts with moderate traffic volumes might provide a better network traffic performance than signalized intersections. Replacing the roundabouts by coordinated and optimized traffic signals provided more improvement to the average sub network travel speed than the average sub network traffic delay.
