The invention discloses an induction coordination control method based on intersection saturation and phase constraint, which is characterized in that grade division is carried out on traffic conditions according to the real-time saturation of an intersection, and six different implementation modes are provided for different grades. Under the busy condition, a way-giving mode is adopted, the coordinated phase can be released in advance and in a prolonged way, but the way is given to any non-coordinated phase; under the medium condition, a permission mode is adopted, the coordinated phase can be released in advance and in a prolonged manner, but the uncoordinated phase is given in sequence; in an idle condition, a permission avoidance mode, a permission neglect mode, a sequence neglect mode or a full-induction coordination mode can be flexibly selected according to phase constraints, so that advanced release and extension of all phases under the constraints are realized. By dynamically adjusting the phase release time sequence and duration, the intersection release is optimized to the greatest extent, so that the induction coordination control requirements of the intersection in different scenes are met.
本发明公开了一种基于交叉口饱和度及相位约束的感应协调控制方法,根据交叉口实时饱和度对通行情况进行了等级划分,并针对不同等级提供了六种不同的实现模式。在繁忙情况下,采用让行模式,协调相位可提前并延长放行,但让行于任何非协调相位;中等情况下,采用许可模式,协调相位可提前并延长放行,但按顺序让行于非协调相位;空闲情况下,根据相位约束可灵活选择许可让行、许可忽略、顺序忽略或全感应协调模式,以实现所有相位在其约束下的提前放行和延长。本发明通过动态调整相位放行时序和时长,最大程度地优化了交叉口放行,以满足交叉口不同场景下的感应协调控制需求。
