摘要：
An integrated optimization model for lane function and signal control is proposed to improve the efficiency and stability of tandem intersections. Based on analyses of three types of tandem control modes and two types of signal control strategies, an optimization model framework was established to minimize the combined value of the mean and semi-standard deviation, considering the constraints of the lane number, signal, and length of the sorting area. The proposed model was solved using the improved Nova Scotia-Gambia Association algorithm. Two case studies were used to analyze the accuracy and optimization effect, which considered the mode optimization of a tandem intersection and the control strategy for a conventional intersection. The results show that the established integrated optimization model could improve the efficiency and stability of the control scheme under different tandem control schemes and traffic conditions. Compared to traditional design methods, the traffic benefits (a 19. 6 1 % decrease in the average delay and 20. 94% decrease in the average queue) and environmental benefits (a 10. 93% decrease in CO production and 12. 97% decrease in NO* production) at the intersection were significantly improved. © 2023 Xi'an Highway University.
