摘　　要：考虑了相位相序相互耦合的特点,建立了交叉口相位相序自动生成和优化模型,并采用两阶段优化方法,第一阶段优化相位,构建相位约束自动生成所有相位,以关键车流流量比之和最小为目标优化相位;第二阶段以关键车流和非关键车流的绿灯间隔时间最小为目标优化相序。最后,以实际案例验证模型能够有效降低交叉口关键车流流量比和绿灯间隔时间,减轻相位设计和决策的难度,有效提高交叉口相位相序设计的效率和科学性,为开发信号控制辅助设计软件奠定了理论基础。This paper presents a novel automatic generation and optimization model of signal phase and phase sequence for signalized isolated intersection,which takes into account the intercoupling of phase and phase sequence. The model optimizes the phase and phase sequence in a unified framework in two stages.The first stage is to optimize the phase scheme. A general automatic generation program of phase scheme is constructed,and the phase scheme is optimized with the objective function of minimizing the flow ratio of key Lane groups. In the second stage,the optimal phase sequence scheme is generated based on the optimal phase scheme and the optimization model aiming at the least phase inter-green time. The proposed optimization model of signal phase and phase sequence is verified by the actual data in signalized intersection. It is shown that this model can reduce the difficulty in phase design and decision-making,which lays a theoretical foundation for the development of signal control aided design software.
