Abstract:

Traffic flow at a signal controlled T-shaped intersection where there are three input directions of vehicles was investigated by the cellular automata model. Because in the previous models some vehicles at intersection only have one steering way, a more realistic model which vehicles on each input lane have two steering directions was introduced. The three phase traffic signal with fixed period was used to control the conflicts of vehicles. The phase diagram and capacity of the system were investigated and compared with previous unsignalized models.

Key words: engineering of communication and transportation, cellular automata, T-shaped intersection
