This paper brings forward a method which improves the work efficiency of the intersection by setting exclusive right-turn lanes combined with the pre-signal control. In conditions of a low flow of the right-turning vehicle but a high flow of the other direction vehicle, it changes right-turning vehicle lane into though-traffic lane combined with the pre-signal control at a certain time of every signal cycle. In the certain time of every signal cycle, through-vehicle can use the right-hand bend lane when through-signal turns to green, which results an increasing efficiency of green signal. The optimal design applies to the small and medium-sized intersection under the traffic condition that the straight flow is high while the right turn flow is low and the road resources are limited. It improves the work efficiency of the entire intersection at the cost of the traffic interests of right turn vehicle, furthermore, it has a small workload and economic input and proved to be feasible under certain conditions.
