Regional Traffic Feature Analysis Method and Application Based on License Plate Recognition Data
In order to analyze the regional traffic characteristics,firstly,the mean and median values are used to clean the license plate recognition data to obtain the road travel time of different periods,and then the road travel threshold is calculated according to the maximum road travel time.Secondly,the road travel threshold is used to divide the cycle travel path into multiple trips,and the travel chain is divided into spatio-temporal information of the travel path.Then,according to the travel chain statistics of traffic generation and attraction,so as to obtain the traffic characteristics in the study area.Finally,taking Yuelu District of Changsha City,Hunan Province as an example,the vehicle sources and main travel modes are analyzed,and the hot spots and hot routes of the local road network are determined.Through the method,regional traffic characteristics can be deeply mined based on license plate recognition data,and further provide data support for traffic planning.
