Non-signalized T-shaped Intersections Mixed Traffic Flow Study

摘要

Combining actual city T-shaped intersection traffic conditions in this paper, we propose a cellular automaton model of mixed traffic flow at T-shaped intersection. In order to avoid a collision between vehicles and gridlock phenomenon occurs, running vehicle in the model adopted the principle of major street vehicles traveling priority. In this paper, a simulation study in the open boundary conditions, three kinds of maximum speed of vehicles mix injected T-shaped intersection lane. Research branch street injection probability respectively impact T-shaped intersection of lane's average velocity and traffic flow. Under the same conditions, different mixing ratio coefficient of the speed are different effects on the traffic flow system. Main lane injection probability affect T-shaped intersection traffic flow within a certain range systems.
