Real-time traffic flow monitoring and early warning induction management system for highway and monitoring method

Abstract

The invention discloses a real-time traffic flow monitoring and early warning induction management system for highway and a monitoring method. The system uses a single vehicle as a basic unit and comprises a vehicle tracker arranged on the vehicle and a monitoring center for carrying out wireless communication with the vehicle tracker; and in the system, a GPS (Global Position System) module of the vehicle tracker is used for receiving vehicle position information in real time, a wireless communication module sends real-time vehicle information to the monitoring center through a wireless network under the control of a processer, a communication module of the monitoring center receives the vehicle information and stores the vehicle information in a storage module, and a data analysis module analyzes the vehicle information and displays an analysis result through an input and output module. By adopting the invention, the sectional real-time traffic flow information of any point on a highway section can be precisely obtained, and accidents or broken down vehicles occurring on any place and in any time on the highway can be found out in the first time so as to decrease the influence of an traffic accident on the traffic condition to the minimum and provide precise reference data for the routing maintenance, operation, management and development of the highway.

Description

technical field [0001] The invention relates to the field of intelligent traffic management, in particular to a real-time vehicle flow monitoring, early warning and induction management system and monitoring method for expressways. Background technique [0002] With the rapid development of the national economy, the construction of expressways has begun to take shape. With the development of automobile transportation, it is very important to accurately grasp the rapid growth of expressway traffic flow for expressway management and development. important management content. [0003] At present, the methods for understanding road traffic conditions (real-time traffic conditions) mainly include: [0004] (1) The method of video monitoring: if the authorized announcement date is January 21, 2009, the invention patent "Video Method for Real-time Collection of Road Traffic Flow Information" with the authorized announcement number CN100454355C adopts contrast distortion and brigh...

Problems solved by technology

The algorithm of this method is complicated, and it is affected by the weather, so the accuracy is not high

The method of video surveillance has the following disadvantages: video detection is a macroscopic method, and it is impossible to obtain microscopic traffic flow information specific to each road section and a specific time point. The frequency of vehicles passing by, the frequency and time rules of traffic jams in a certain road section cannot be obtained

By installing detection devices at regular intervals along the expressway, the real-time traffic flow information of each monitoring point can be obtained more accurately. By comparing the traffic flow data of two adjacent detection devices, the distance between the adjacent detection points can be obtained. Traffic flow changes, so as to provide a reference for dealing with sudden abnormal situations, but it is impossible to accurately obtain real-time traffic flow information at any point on the expressway section, and it is impossible to find any place on the expressway at any time. early warning
