The embodiment of the invention provides an intersection signal control timing optimization method and device using a special phase sequence. The method comprises the steps that the flow direction flow and the flow direction traffic capacity of each flow direction of an intersection and the stage green time ratio of each stage of the intersection are acquired; when one flow direction relates to a plurality of stages, adjusting the green time ratio of each stage according to the flow direction flow and the flow direction traffic capacity; and optimizing the green light time of each stage of the intersection according to the adjusted stage green time ratio. According to the technical scheme provided by the embodiment of the invention, the stage green time ratio of each stage of the intersection is optimized according to the flow direction flow and the flow direction traffic capacity of each flow direction related to a plurality of stages, a more accurate stage green time ratio is obtained, and therefore, a signal control timing scheme is obtained, and the traffic fluency of the intersection is improved.
本发明实施例提供了一种使用特殊相序的交叉口信控配时优化方法及装置,所述方法包括:获取交叉口各流向的流向流量和流向通行能力、交叉口每个阶段的阶段绿信比;当一个流向涉及多个阶段时,根据所述流向流量和所述流向通行能力调整各阶段绿信比;根据调整后的阶段绿信比优化交叉口的各阶段的绿灯时间。本发明实施例的技术方案根据涉及多个阶段的各流向的流向流量和流向通行能力优化交叉口每个阶段的阶段绿信比,获得更为准确的阶段绿信比,据此获得信控配时方案提高了交叉口交通的流畅性。
