Description

A highway grid management system and method based on ETC gantry data

technical field

The invention belongs to the technical field of intelligent transportation, and relates to an expressway grid management system and method based on ETC gantry data.

Background technique

The rapid increase of private cars has brought greater pressure to highway traffic. The influx of private cars has seriously tested the traffic capacity and service quality of the highway, and will bring about problems such as "high-speed congestion" and "prone accidents". Therefore, it is particularly important to strengthen the inspection of highways. At present, there are two main methods for inspections on expressways, namely: (1) use video surveillance to view road conditions in real time; (2) conduct vehicle inspections by front-line staff. In the second inspection method, there are uncertainties in human factors or objective factors, which can easily lead to missed inspection of some road sections, thereby affecting the traffic safety of the road; moreover, this method is easy to cause the inspection purpose is not strong, waste manpower and material resources , and the inspection efficiency is low. Grid management originates from urban management and is a kind of administrative management reform. It divides the area in the city into several grids according to certain standards or forms, and establishes a management system by strengthening the inspection of components and events in the grid. method. The idea of urban grid management is applied to the operation and management of expressways. A expressway is divided into several unit grids, and the grid length, section length and road length are configured to form a three-level management system.

At present, the ETC gantry system has covered the national expressway network and has become an important means of expressway billing. The ETC gantry traffic data includes the license plate information and travel time information of the passing vehicles. The traffic data can be directly connected to the settlement center of the Provincial Department of Communications or the cloud data platform of the expressway operating unit through the KAFKA of the toll station. Therefore, it is possible to combine ETC-based gantry traffic data with grid management to standardize the vehicle inspection process, changing from the randomness, coping and blindness of inspections in the past to timeliness, comprehensiveness and accuracy. At the same time, the management methods are also digitized and programmed, which ensures the agility, precision and efficiency of management.
