Real-time road condition information acquisition method and system

Abstract

The invention is suitable for the data acquisition processing technology field and provides a real-time road condition information acquisition method. The acquisition method is based on intelligent equipment with a positioning function and a cloud server cluster which establishes data communication connection with the intelligent equipment. The method comprises the following steps that A, through the intelligent equipment, a preset time interval mode is used to collect and acquire longitude and latitude position data and record a time value (T); B, the collected position data is uploaded to a cloud server through using data communication; C, the cloud server carries out motion speed and road crowding degree analysis on the received data; D, the analyzed data information is mapped to a map of a map server. In the invention, through existing intelligent data terminal, an extra investment is not needed; cost is low; a method operation is simple and a participant can easily participate in; an APP client only needs to be downloaded and an extra operation is not needed; data acquisition is completed automatically; real-time data is rapidly updated and data accuracy is increased.

Description

technical field [0001] The invention relates to the improvement of real-time information collection and processing technology, in particular to a method and system for collecting real-time road condition information. Background technique [0002] With the rapid development of China's economy, road construction extends in all directions, and the degree of urbanization is becoming more and more intensive. Automobiles, trains, high-speed bullet trains, airplanes and other means of transportation are developing faster and faster. Among them, the aggregation and sharing of road condition information is already very necessary. very meaningful thing. [0003] With the development of social economy and transportation, many problems such as reduced road capacity, reduced driving speed, increased traffic delays, increased fuel consumption, and aggravated environmental pollution caused by traffic congestion and traffic accidents have become more and more prominent. Problems of common ...

AI Technical Summary

Problems solved by technology

Fixed traffic information collection technology is to install ring sensors, microwave monitors and other electronic equipment on main roads and important intersections to monitor traffic data at a certain cross-section of a specific road section on the road network: traffic flow, occupancy rate, etc., and then obtain the average Vehicle speed, road traffic congestion and other information, but obtaining these data needs to be estimated by complex algorithms

The advantage of these devices is that the measurement of traffic flow is relatively accurate. The disadvantage is that the cost of equipment deployment and maintenance is high. Therefore, they are generally only deployed on main roads in cities with low coverage.

[0005] At present, the existing fixed-type collection of information is poor in randomness, low in positioning accuracy, single in collection data, and low in precision in statistical data. Only fixed-type collection of data can be achieved, and because the fixed equipment is located at the intersection, it cannot be completed. Comprehensive collection of routes, the information accuracy of the formed road conditions is low
