Abstract: In this paper, aiming at the problem of the increase of the overall delay caused by the inaccurate flow data in the line control system of road intersections, the data accuracy is improved by fusing the data obtained by different acquisition equipment, and the index data of specific cases are compared and analyzed by VISSIM simulation, which shows that the road green wave control technology based on multi-source data fusion can improve the system efficiency, reduce the overall delay and improve the service level of road operation.

Keywords: multi-source information; on-line control system; VISSIM; road green wave control technology; on-line control model

近年来,随着我国城市化的推进,机动车保有量也快速增长,城市交通拥堵问题日益严重,交通问题已经严重影响城市发展,交通管理部门一方面对城市道路网络进行优化,另一方面通过交叉口组织与管理来提升路网容量、缓解交通压力,是目前提高道路服务水平的重要措施。(剩余4562字)
