The embodiment of the invention provides an interval speed measurement method and device, and the method comprises the steps: receiving vehicle interval speed measurement data uploaded by a target monitoring device through presetting a plurality of monitoring device pairs, enabling the monitoring device pairs to be arranged in a staggered or nested manner, determining a corresponding speed measurement interval according to the vehicle interval speed measurement data, and transmitting the speed measurement interval to the target monitoring device pair. Querying all midpoint monitoring devices in the speed measurement interval, performing distance matrix construction operation and time matrix construction operation on the plurality of midpoint monitoring devices according to the target monitoring device, determining a corresponding distance matrix and a time matrix, determining a corresponding vehicle speed average value and a vehicle speed standard deviation according to the distance matrix and the time matrix, and determining the vehicle speed average value and the vehicle speed standard deviation according to the vehicle speed average value and the vehicle speed standard deviation. According to the vehicle speed average value and the vehicle speed standard deviation, interval speed measurement calculation operation is carried out, the corresponding vehicle average running speed is determined, the vehicle average running speed is compared with the preset speed limit value, the corresponding vehicle speed measurement result is determined, and the accuracy of interval speed measurement can be improved.
