Characteristics of Traffic Flow at Non-Signalized T-Shaped Intersection

At the non-signalized T-shaped intersection,there are three types of vehicles,such as straight-driving vehicles,left-turning vehicles and right-turning vehicles.The cellular automata model is proposed to explore the characteristic of traffic flow at the non-signalized T-shaped intersection with all directional vehicles.The rules are applied to avoid the conflicts between different directional vehicles and the gridlock happen.The influence of inflow rates,left-turning vehicles and right-turning vehicles on each lane flux is discussed.This paper especially focuses on right-turning vehicles.Simulation results indicate right-turning vehicles can enhance the flux of the minor street and the inner lane of the major street but restrain the flux in outer lane of the major street.It is observed that when the inflow rates of the inner lane in major street is low enough and the inflow rates of the outer lane in major street is high enough,right-turning vehicles in minor street can enhance the flux in outer lane of major street.
