Abstract

The invention discloses a method for obtaining a vehicle travel path and an OD (Origin-Destination) matrix in a statistic period. The method comprises the following steps: dividing traffic zones and roads in a certain road network area; placing a vehicle detecting device at an exist or an entrance behind each road section or combined road section to detect an unique identifier of a travelling vehicle; in the statistic period, collecting information of the vehicles travelling on the road without interruption by utilizing the vehicle detecting devices, and storing the information into a background database; extracting time and position data of each vehicle within the statistic period to obtain path information of the vehicle within the statistic period, and storing; obtaining the traffic zones, in which the origins and the destinations of the vehicles are located according to the path information, and comprehensively considering origins and destinations of all vehicles, so as to obtain the OD matrix within the counting period. According to the method disclosed by the invention, based on the vehicle identifiers, the vehicle travel path and the OD matrix are dynamically obtained and updated by various data excavating and fusing methods and an advanced computer real-time processing technology.

Description

technical field

[0001] The invention belongs to the field of traffic planning and management, and specifically relates to a vehicle travel route and OD (ORIGIN-DESTINATION) matrix acquisition method within a statistical cycle based on Vehicle Identification (VID), which can be achieved with high frequency, low cost, and automation And intelligently acquire the statistical cycle, such as morning and evening peak vehicle travel routes and OD matrix data, which can be used in various traffic management tasks and services such as traffic planning, traffic demand, traffic forecast and guidance. Background technique

[0002] Vehicle travel OD matrix is ​​the core basic information of transportation system planning, design and operation management. The accuracy of OD information directly affects the accurate judgment of urban traffic managers and traffic planning engineers and technicians on the current traffic situation and possible future traffic situations, and will directly aff...

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0023] figure 1 It shows the traffic road network of a certain small area, which is composed of 6 intersections, and the trajectory of a certain marked vehicle has passed 13 vehicle detection devices. Exit or entrance, that is, the exit or entrance of the road section (or composite road section) on one side of the traffic area. The purpose of the present invention is to obtain the following information: the unique identification of the vehicle (license plate number, or electronic tag, etc.), the time when the vehicle passes the vehicle detection equipment, the serial number of the corresponding vehicle detection equipment, and obtain the morning and evening peak vehicle travel route according to the obtained information ...
