Problems solved by technology

[0004] The patent specification with application number 201510645296.7 discloses a method for laying out urban road traffic detectors. This application uses an undirected graph G(V,E) to model the urban road network, and assigns three parameters to each road: Boolean variables of whether traffic detectors are installed, the detected or estimated Boolean variables and their importance in the entire road network; optimize the entire model, and decide to maximize the detection of important road sections; however, this patent cannot realize Quickly select monitoring points under the large-area road network to make up for the lack of monitoring of existing monitoring points and overcome the problems of large manpower and material resources in traditional on-site investigation methods, and also provide strong data support for the distribution of urban control points

Embodiment Construction

[0047] The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

[0048]In order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0049] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

[0050] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] like figure 1 Shown, a kind of method based on truck GPS data monitoring overrun monitoring, including the following steps:

[0052] S1: Screen and clean the GPS data of the vehicle to obtain the GPS data of the freight vehicle;

[0053] S2: Divide vehicle travel status based on travel angle and truck speed, identify truck travel stop points, and mark truck travel chains;

[0054] S3:...

Abstract

The present invention provides a monitoring point distribution method for overcrowding control based on the GPS data of trucks. The method screens and cleans the GPS data of the vehicles to obtain the GPS data of the trucks; then, divides the travel status of the vehicles based on the travel angle and the speed of the trucks, and identifies the trucks. Travel stop points, mark the truck travel chain; then, based on the direction matching method and the shortest distance method, match the moving points in the truck travel trajectory to the urban road network; then, construct the daily average passing frequency and daily average passing number two The evaluation index calculates the daily average passing frequency and the daily average passing number of trucks on each road; then, constructs a road comprehensive passing index based on the daily average passing frequency and the daily average passing number, and ranks the importance of road sections. Select the road section with the highest comprehensive passing index value to form a monitoring layout plan; finally, construct two evaluation indicators, the daily average detection vehicle ratio and the truck travel coverage rate, to evaluate the monitoring effect of overcrowding control after the newly added monitoring points.

Description

technical field [0001] The invention relates to the technical field of monitoring overruns by science and technology, and more particularly, relates to a point distribution method for monitoring overruns based on truck GPS data. Background technique [0002] Over the years, due to irregularities in the cargo transportation market, low freight rates, and huge freight volumes, coupled with the fact that the means of law enforcement agencies to investigate and deal with overloading and overloading is backward and single, and the law enforcement personnel are insufficiently equipped, enterprises and drivers have a fluke mentality, and they have lost their economic interests. The phenomenon of over-limit and overloading is serious. Overloading of freight vehicles often leads to frequent traffic accidents and endangers the service life of roads and bridges. Therefore, urban science and technology governance work is still an urgent problem to be solved. [0003] The reasonable se...
