The invention discloses a self-adaptive variable lane control method and system for a signal control intersection. The method comprises the steps: collecting the historical flow data of the intersection, and determining the period of each conversion of a lane function according to the flow change rule of an entrance; taking the traffic load degree index of a current intersection as a basis for lane function conversion; according to the conversion period and the traffic load degree index of the current intersection, judging whether lane conversion is carried out or not; if so, switching a pre-signal, and optimizing the timing of a main signal; otherwise, keeping an original signal scheme; judging whether the optimized signal scheme is superior to the original scheme or not, and if so, changing the current signal scheme into the optimized scheme; otherwise, keeping the original signal scheme. The method can adapt to traffic flows, changing continuously along with time, of all vehicle flows at the intersection, and the phenomenon that a lane in one flow direction is crowded and a lane in the other flow direction is vacant is avoided.
本发明公开了一种信控交叉口的自适应可变车道控制方法及系统,包括:采集交叉口历史流量数据,根据进道口流量变化规律确定车道功能每次转换的周期;将当前交叉口的交通负荷程度指标,作为车道功能转换的依据;根据转换周期以及当前交叉口的交通负荷程度指标,判定是否进行车道转换;如果是,切换预信号,对主信号的配时进行优化;否则,保持原信号方案;判断优化后的信号方案是否优于原方案,如果是,将当前信号方案变为优化后的方案;否则,保持原信号方案。本发明能够适应交叉口各车流随着时间不断变化的交通流,避免出现某一流向车道拥挤,另一流向车道空置的现象。
