A Novel Method of Trip Route Estimation based on Vehicle License Plate Recognition System

With the development and application of vehicle license plate recognition system, a novel trip route estimation method was proposed. vehicle license plate recognition vehicle path estimation method was proposed, first used GRUBBS to eliminate invalid data, and then proceed shield survey points route's traffic assignment through the survey point OD matrix, then using the link flow to supplement and recovery the points OD, through iterative get the final path flow between the survey points. Finally, through the Bayes’ theorem connecting the route of survey points can get the trip route. Vehicle travel path is one of the basic data of the intelligent transportation system, which plays an important role in traffic management and traffic control. According to the instance of Chengcheng County counties arterial road network analysis, this method is feasible, and the resulting information is basically in line with the actual path.
