Study of Traffic Flow Model Based on Adventure Ratio and Braking Distance Difference

Abstract

With open boundary conditions, the cellular automaton traffic flow model based on adventure ratio and braking distance difference was built. The fundamental diagrams of traffic flow with adventure ration effect under different parameters were present by numerical simulation, then the characters of transition between free flow phase and jamming phase was analyzed. It turned out that adventure ration plays an important effect on the traffic density, average speed and phase transition point. The result will provide valuable reference for real traffic flow fitting study by selecting right adventure ratio.
