Traffic Assignment of Al-Kufa City Using TransCAD

Abstract

Abstract Modern urban cities around the world suffer from high congestions due to high daily trips for different purposes. Al-Kufa city has a lot of congested roads in its road network. The main objective of this study is to evaluate the current traffic situation. Firstly, the number of links and nodes has been counted using GIS software. These links represent major and minor arterials. The collected data include flow, speed and geometric characteristics for each link and node in the network. The traffic assignment model (Stochastic User Equilibrium) in TransCAD software was adopted in this study. The results indicated that the value (v/c) for most of these roads is more than one which indicated congested roads.
