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.
