Abstract

The invention provides a road trip time estimating method and a road trip time estimating system, wherein the method comprises the following steps that the vehicle passing information in the set time is collected at an upstream tollgate and a downstream tollgate, in addition, the license plate matching is carried out, and the vehicle trip time information set is obtained; the vehicle trip time information set is subjected to data preprocessing; the preprocessed time information set is subjected to distribution test for judging the distribution mode; and the road trip time estimating value is calculated according to the judged distribution mode. The method and the system have the advantages that the intelligent degree is high, the operation is simple and convenient, and the objective degree and the accuracy of calculation results are high.

Description

technical field [0001] The invention belongs to the field of urban road intelligent traffic management and information service, and in particular relates to a method and system for estimating road travel time. Background technique [0002] In recent years, my country's urban road traffic management level has been continuously improved. At the same time, in order to effectively manage various traffic violations, many cities in my country have installed a large number of comprehensive illegal monitoring systems at urban signal control intersections or road sections. With the development of video technology With the development, these comprehensive illegal monitoring systems can be used as road checkpoints scattered in the city while capturing illegal activities, and can record all relevant information of vehicles passing through the intersection, mainly including: recognized license plate number, passing through the intersection The time of the vehicle, the steering and speed of...
