Abstract: When the conflicts between the left-turn vehicles and the through vehicles have happened at the signalized intersection, we consider different driver behaviors and divide the drivers into two types: the following driver and the humility driver, and build a model of the left-turn vehicles going through the intersection. The impact on the intersection’s capacity by the different driver behavior is studied. The results show that when all the drivers are the following drivers, with the increase of the traffic flow, the capacity of the intersection decreases sharply. When all the drivers are the humility drivers, considering the situation that the policeman directs traffic, the capacity of the intersection will be better. These results can explain the reason for the blocking of the intersections at the heavy traffic time in China well. We can improve the capacity of the intersections by changing the driver behavior and by directing traffic by a policeman.

Key words: driver behavior, intersections, capacity
