Simulation Traffic Flow in Urban Arterial Streets Using CFD (Army Canal Street as a Case Study)

Abstract

computation fluid dynamics (CFD) is a branch of fluid mechanics that has been widely and successfully applied to different fields of engineering researches by using the numerical analysis and data structures to analyze and solve problems that involve fluid flows. The aim of this paper concentrated on simulation process of traffic flow of particular section of Army Canal Street by using CFD approach. It is found that the tremendous potential to analyze the traffic flow by the CFD approach by providing an estimation of the unknown value of traffic flow in the exits or entries based on collected data of the upstream and downstream or vice versa. This process will help in reduce the time, effort and cost in the traffic count calculation process for a specific segment. The CFD has the capability to clarify visually the high and low regions of the traffic flow on the roadway section based on the colored contour legend.
