The invention discloses an intersection self-adaptive signal control algorithm, which is used for formulating a group organization and self-adaptive signal timing scheme for real-time traffic flow at an intersection. The method comprises the following steps of traffic state basic data acquisition, road network traffic flow motion simplified modeling, signal control element modeling, intersection maximum pressure calculation and phase activation control strategy. The data required by the signal control algorithm is only the queuing length of the entrance lane. The algorithm is realized through a program written by an API port in the VISSIM, and the running efficiency and the running stability of vehicles at nine intersections in Tianjin are analyzed. The invention discloses a set of distributed signal control strategies, and overcomes the defect that currently common central control type signal control needs high equipment cost. Meanwhile, the control algorithm can ensure that the number of vehicles passing through the intersection is kept at a high level, the queuing length is stabilized within a certain range, and an innovative method is provided for signal control and timing schemes.
本发明公开了一种交叉口自适应信号控制算法,用于针对交叉口实时车流制定组组织、自适应的信号配时方案。该方法包括以下几个部分:交通状态基础数据获取、路网车流运动简化建模、信号控制要素建模、交叉口最大压强计算、相位激活控制策略。该信号控制算法所需要的数据只有进口道排队长度。本发明通过VISSIM中的API端口编写的程序来实现该算法,分析了天津市九个交叉口的车辆运行效率与运行稳定性。本发明公开了一套分散式信号控制策略,克服了当下常用的中央控制式信号控制所需高昂的设备费用的缺点。同时,该控制算法能够保证交叉口通过车辆数保持较高水平,且将排队长度稳定在一定范围内,为信号控制和配时方案提供了一种创新性的方法。
