The invention relates to the technical field of road traffic signal control, and particularly discloses a signal control intersection traffic jam evaluation method. The method comprises the followingsteps of respectively measuring the queuing time of the queuing vehicles at each entrance lane of a signal control intersection in a preset time period, and simultaneously obtaining an actual signal control period of the signal control intersection; calculating the maximum queuing time index of each entrance lane of the signal control intersection in the preset time period according to the queuingtime of the queuing vehicles at each entrance lane and the actual signal control period; determining a queuing time index result of the signal control intersection in the preset time period accordingto the maximum queuing time index of each entrance lane of the signal control intersection; and determining the congestion level of the signal control intersection in the preset time period. The invention further discloses a signal control intersection traffic jam evaluation device and system. According to the signal control intersection traffic jam evaluation method provided by the invention, the intersection jam state can be quickly obtained, and support is provided for the signal control intersection traffic improvement.
本发明涉及道路交通信号控制技术领域,具体公开了一种信号控制路口交通拥堵评价方法,其中,包括:分别测定预设时间段内信号控制路口的每个进口道排队车辆的排队时间,同时获取该信号控制路口的实际信号控制周期;根据每个进口道排队车辆的排队时间和实际信号控制周期计算预设时间段内信号控制路口的每个进口道的最大排队时间指数;根据信号控制路口的每个进口道的最大排队时间指数确定预设时间段内信号控制路口的排队时间指数结果;确定信号控制路口在预设时间段内的拥堵等级。本发明还公开了一种信号控制路口交通拥堵评价装置及系统。本发明提供的信号控制路口交通拥堵评价方法可以快速获得路口拥堵状态,为信号控制路口交通改善提供支撑。
