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

Embodiment

[0034] Example: such as figure 1 Shown is the expressway real-time traffic monitoring, early warning and induction management system with a single vehicle as the basic unit in this embodiment, including a monitoring center 2 and several vehicle trackers 1 . A vehicle tracker can track a vehicle, so a monitoring center 2 can obtain the data information of several vehicles. In theory, the monitoring center 2 can obtain the information of all vehicles equipped with vehicle trackers.

[0035]At present, a payment IC card can be obtained when the vehicle passes through the toll booth at the entrance of the high-speed section. Vehicle tracker to ensure the accuracy of traffic monitoring. The vehicle tracker 1 and the payment IC card can be separate devices, or can be integrated in the same device. When the vehicle arrives at the toll booth at the exit of the expressway section, return the payment IC card and the vehicle tracker 1 .

[0036] The vehicle tracker 1 includes a GPS mo...

Embodiment 2

[0054] Embodiment 2: except that the expressway real-time traffic monitoring early warning induction management system of the present embodiment comprises all equipment of embodiment 1, vehicle tracker 1 also comprises the prompting module 14 that links to each other with processor 12, and GPS module 11 comprises the calculating vehicle speed means, the processor 12 includes means for judging whether the vehicle is speeding.

[0055] The GPS module 11 of the vehicle tracker 1 calculates the real-time vehicle speed information according to the received position information and time information, and feeds it back to the processor 12. The processor analyzes and judges the vehicle speed information. When the vehicle speed exceeds the upper limit value of the vehicle speed, the processor 12. Control the prompting module 14 to perform overspeed prompting. The prompting module 14 is a display screen, displaying speeding prompt information; or a loudspeaker, voice prompting speeding; ...

Embodiment 3

[0056] Embodiment 3: the expressway real-time traffic monitoring early warning induction management system of the present embodiment except comprising all equipment in embodiment 1 or embodiment 2, vehicle tracker 1 comprises memory 15 and prompting module 14 that are connected with processor respectively, Stored in the memory is a location information base of expressway tollbooths, and the prompting module 14 is used for prompting when the vehicle drives to the tollbooth and reaches a certain distance from the tollbooth.

[0057] The processor 12 compares the real-time location information of the vehicle with the location information of the toll booth in the memory 15, and judges that when the vehicle is traveling in the direction of the toll booth and there is still a certain distance between the vehicle and the toll booth, the processor 12 controls the prompt Module 14 prompts. The prompt module 14 in the present embodiment is a display screen, which shows information such ...

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...
