To improve the control efficiency of the signalized intersection control scheme

the algorithm for optimal intersection signalization scheme was proposed by considering movement lapping. Firstly

the movement compatibility relation in intersections were analyzed and refined

and the phase movements’ combination was determined. Then

the phase movements’ combination was represented and the random samplings were re-arranged. According to the phase setting requirements of intersection signal control scheme

the feasible phase combination (FPC) schemes for intersections were obtained by selecting the phase combination schemes satisfying the condition and consideration of the movement lapping. Finally

the signal phase timing and average vehicle delay were calculated by combining the existing timing model

and the control scheme corresponding to the minimum average delay was selected as the optimal control scheme of the intersection by comparing the average vehicle delay. Analysis results showed that the average delay of movement vehicles under the proposed scheme was reduced by 0.3 s/pcu compared with the ring barrier controller structure phase combination scheme (RBS)

0.5 s/pcu compared with the diffluence phase combination scheme (DS)

and 4.5 s/pcu compared with the combination phase combination scheme (CS). Therefore

it showed that the proposed method is feasible.
