Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-level early warning system and method based on vehicle-road coordination that can provide drivers with multi-level warnings according to different traffic conditions and provide drivers with vehicle driving decisions, so as to solve the problems in the above-mentioned background technology. The driver's instructions on the existing construction roads cannot be flexibly changed according to the actual situation, which may easily cause technical problems such as waste of road resources and traffic delays

Embodiment 1

[0048] Such as figure 1 As shown, Embodiment 1 of the present invention provides a multi-level early warning system for construction roads based on vehicle-road coordination. The system includes a traffic flow information collection module, an early warning information processing module, and a vehicle control module;

[0049] The traffic flow information collection module is used to collect the traffic flow information of the construction road, and send the traffic flow information to the early warning information processing module;

[0050] The early warning information processing module is used to receive the traffic flow information, obtain early warning parameter information according to the traffic flow information combined with construction location and vehicle information, and judge whether to send early warning information to the on-board control module, and send the early warning information to the on-board control module;

[0051] The on-board control module is used...

Embodiment 2

[0068] Such as figure 2 As shown, Embodiment 2 of the present invention provides a process of using the system described in Embodiment 1 for early warning. The system includes a traffic flow information collection module, an early warning information processing module, and a vehicle control module.

[0069] In Embodiment 2 of the present invention, the traffic flow monitoring radar is used as the vehicle flow information collection module, and the traffic flow monitoring radar is installed at a position 3 kilometers away from the starting point of the construction area to monitor the traffic flow of each lane in real time. The traffic flow information of the construction road is collected by the device, and the traffic flow information is sent to the early warning information processing module through the flow transmitter;

[0070] In Embodiment 2 of the present invention, the console serves as the primary early warning information processing unit to receive the traffic flow ...

Embodiment 3

[0080] Such as image 3 As shown, Embodiment 3 of the present invention provides a multi-level early warning method for construction areas based on vehicle-road coordination technology under dynamic traffic flow. The method includes:

[0081] S1. The traffic flow monitoring radar collects flow information (Q) and sends the information to the console. At the same time, after the console receives the flow information Q, it is displayed to the technician through the display, and the technician inputs the current level according to the current flow. Warning position (X 1 ) and the secondary warning position (X 2 ), it is sent to the central controller by the signal transmitter. In this embodiment, according to the U.S. "Traffic Control Facilities Manual" (MUTCD, 2009) and China's "Highway Maintenance Safety Operation Regulations" (JTG H30-2015), the traffic flow Q is set to 800 vehicles / hour, and the primary warning position X 1 It is set at a position 2 kilometers away from th...

Abstract

The invention discloses a multi-level early warning system and method for a construction area based on vehicle road cooperation technology under a dynamic traffic flow. The system comprises a trafficflow information collection module which is used for collecting traffic flow information of a construction road; an early warning information processing module which is used for obtaining early warning parameter information with combination of the construction position and the vehicle information according to the traffic flow information and for determining whether to sent early warning information with combination of the early warning parameter information; and a vehicle-mounted control module which is used for collecting the vehicle information and sending the vehicle information to the early warning information processing module and receiving the early warning information. The system guides the driver to execute the driving strategy under different traffic conditions by real-time monitoring and tracking of the road traffic state and the current state of the vehicle, effectively controls the random convergence behavior of the vehicle, reduces the traffic delay caused by the random lane change, and improves the traffic efficiency. Meanwhile, through multi-level warning, the possible traffic accidents are reduced and the safety of the construction area is ensured.

Description

technical field [0001] The invention relates to the technical field of traffic safety control, in particular to a multi-level early warning system and method for construction roads based on vehicle-road coordination. Background technique [0002] With the acceleration of the transportation infrastructure construction process, more and more road construction areas are generated due to reconstruction, expansion and maintenance operations. The emergence of road construction zones has greatly reduced road traffic capacity, and drivers, as the most active and uncontrollable factor in the traffic system, are prone to large fluctuations in their behavior in such a complex driving environment as construction zones. Taking corresponding driving measures in time may cause serious traffic accidents. Therefore, reducing the adverse effects of construction areas on drivers and improving vehicle operating efficiency has become one of the problems to be solved urgently. [0003] At prese...
