The invention provides a signal intersection standard vehicle accurate conversion method, device and system, and relates to the technical field of urban traffic management. The signal intersection standard vehicle accurate conversion method comprises the following steps: acquiring traffic data of a signal intersection; and selecting a combined index of driving time and vehicle length or a time headway from the traffic data as a conversion index, and determining a standard vehicle conversion coefficient according to the conversion index. According to the technical scheme, the combined index of the driving time and the vehicle length or the time headway is selected as the conversion index to determine the standard vehicle conversion coefficient, the standard vehicle conversion coefficients under the heterogeneous traffic flow and the homogeneous traffic flow are determined respectively, and the influence of the vehicle on the traffic flow is measured by using the space-time resource occupied by the vehicle, and the standard vehicle conversion index construction is more scientific so that the standard vehicle conversion coefficient of the signal intersection is accurately determined.

    本发明提供了一种信号交叉口标准车精确换算方法、装置及系统,涉及城市交通管理技术领域。本发明所述的信号交叉口标准车精确换算方法,包括:获取信号交叉口的交通数据;从所述交通数据中选取行驶时间和车辆长度的组合指标或车头时距作为换算指标,根据所述换算指标确定标准车换算系数。本发明所述的技术方案,通过选取行驶时间和车辆长度的组合指标或车头时距作为换算指标以确定标准车换算系数,分别确定异质交通流和同质交通流下的标准车换算系数,且使用车辆占用的时空资源衡量车辆对交通流的影响,使得标准车换算指标构建更加科学化,从而精确确定信号交叉口的标准车换算系数。
