Abstract

Extensive research has been done to model and simulate traffic flow in order to answer valuable questions in the implementation of different traffic policies. A major open question is whether or not the stay right except to pass rule is an efficient traffic policy in terms of traffic flow and safety. We develop a particle-interaction based model which stems from how cars react and make decisions using locally restricted knowledge and observe how snapshots of these processes over a large closed continuous road govern the dynamics of the overall traffic flow. Through computer simulation, we observe and analyze the difference among four traffic policies or rules which determine how cars react to an impending accident: 1) passing on the left or right if able (free passing); 2) passing strictly on the left and then returning to right most lane (single driving); 3) passing on the left and then returning to any open lane on the right (single passing); and 4) not allowing any passing (no passing) in both low and high density traffic.
