Path fitting method based on ETC portal frame

Abstract

The invention relates to a path fitting method based on an ETC portal frame in the technical field of traffic information. The path fitting method comprises the following steps: acquiring informationof passing vehicles through each acquisition terminal device arranged in a highway network; transmitting the collected information to a background data processing center through a network channel, andprocessing; screening to obtain an effective vehicle data set; carrying out fitting processing according to time and places; marking the passing points on a GIS map; remotely connecting an inspectiontracing module through a network; and after the vehicle passing data information in a storage database is called, graphically displaying the vehicles and passing information needing to be traced by connecting to a passing information display module. According to the ETC portal frame-based path fitting method provided by the invention, basic data acquisition is rapid and complete, vehicle drivingpath calculation is accurate, and annotation display is vivid and intuitive.

Description

technical field [0001] The invention relates to the technical field of traffic information, in particular to a path fitting method based on an ETC gantry. Background technique [0002] Under the new background of the major reform of the national expressway free flow toll model, the importance of audit work must be particularly prominent. Vehicle route query is a very important link in the audit work. However, the image recognition device of the expressway mast is affected by insufficient light and supplementary light at night, and the recognition rate of vehicles and license plates is not high. These practical problems directly affect the identification ability of entering and exiting vehicles, resulting in some normal driving. The mast driving data of the vehicle is missing, and the intentional shielding of the OBU equipment, the inconsistency of the vehicle card and other means lead to the missing of the mast driving data of some toll-evading vehicles, making it possible ...

However, the image recognition device of the expressway mast is affected by insufficient light and supplementary light at night, and the recognition rate of vehicles and license plates is not high. These practical problems directly affect the identification ability of entering and exiting vehicles, resulting in some normal driving. The driving data of the mast of the vehicle is missing, and the intentional shielding of the OBU equipment, the inconsistency of the vehicle card and other means lead to the loss of the driving data of the mast of some toll-evading vehicles, making it possible for illegal toll-evading vehicles to ride
