Simulating traffic flow for emergency evacuation in Manhattan, KS using Rockwell ARENA
… scenarios as well, such as natural disasters or chemical spills, and this information can be applied to such events. This paper discusses the creation and analysis of a discrete-event simulation using ARENA software. The simulation described several scenarios. They were a base case scenario with …
