Urban road motor vehicle flow and run guiding method and real-time flow statistical system

Abstract

The invention is a kind of automobile guiding and leading method in city, which includes following steps: (1) the automobile sensors on the crossing receives the road occupying stat, speed, and the queuing length etc. information of automobile; (2) the information is transmitted to itself microprocessor; (3) the microprocessor carries on initiative process; (4) the processed data is transmitted to the flow statistic centre; (5) the centre works out the pass index of each crossing; (6) classifies the crossings into different passing grade according to the passing index; (7) the centre transmits the passing grade data to the displaying board on each crossing; (8) the displaying board displays the information in real-time and dynamically. The steps belongs step (5) may be realized with another project. The invention also provides the flow real-time statistic system.

Description

technical field [0001] The invention relates to an urban road motor vehicle diversion and guiding method and a real-time flow statistics system used in the method. Background technique [0002] With the rapid development of social economy, the automobile industry has entered a stage of rapid development. For example, in recent years, the ownership of urban motor vehicles in my country has maintained an annual growth rate of more than 25%. The contradiction between the rapid growth of urban motor vehicle ownership and the limited urban roads and urban space, as well as the contradiction between vehicles and other traffic resource users, has become increasingly prominent, and the traffic congestion and congestion in major cities are becoming more and more serious. Only relying on road construction and bridge expansion cannot fundamentally solve problems such as traffic congestion and traffic accidents. Therefore, urban road traffic construction, planning departments and traf...

AI Technical Summary

Problems solved by technology

Only relying on road construction, bridge construction and expansion can no longer fundamentally solve the problems of traffic jams and traffic accidents.

Therefore, urban road traffic construction, planning departments and traffic management departments have begun to adopt modern high-tech to combine construction and management; The traffic conditions information of similar and adjacent roads can be used to guide them; it is also impossible to automatically and real-time conduct scientific and reasonable diversion of vehicles in motion according to the current traffic conditions of each road, so as to realize the high efficiency of road resources use

Therefore, the series of problems in traffic management cannot be solved fundamentally.

Traditional urban road motor vehicle diversion and guidance methods are limited to the orderly passage of vehicles at road intersections (traffic conflict points) through the traffic command light system located at each intersection

Or reduce traffic conflict points by building a three-dimensional intersection road bridge system, this method has been far from meeting the objective needs of managing and dredging the supported urban traffic

Moreover, due to the lack of real-time collection and statistical analysis of road traffic flow, it is difficult for traffic management departments to find the crux of urban road traffic congestion, so they cannot take targeted and effective measures to improve urban traffic conditions
