Embodiment 1

[0038] After the roadside control system is turned on, the main program starts automatically, and multiple threads are started, respectively calling the data reading processing module, the core algorithm running module, the algorithm result output module and the data storage and uploading module. The specific working steps are as follows:

[0039] Step S1: the data reading processing module reads and standardizes the traffic state data in real time through communication with the detector and the roadside communication unit;

[0040] Step S2: The core algorithm operation module formulates a management and control scheme for speed limit control and dynamic lane control according to the standardized traffic state data in step S1;

[0041] Step S3: the algorithm result output module processes the management and control scheme into standardized result information, the communication interface is an RJ45 network port, and the standardized result information is sent to the roadside com...

Abstract

The invention relates to a roadside control system for expressway construction areas at a vehicle-road cooperative environment. The roadside control system comprises a data reading and processing module, a core algorithm operation module, an algorithm result output module and a data storage and uploading module; the roadside control system is connected in communication connection with a roadside communication unit, a detector and a variable information board through communication interfaces; vehicle road information of the upstream of a construction area is collected, multi-dimensional speed limiting control and dynamic lane control are carried out on networked vehicles and non-networked vehicles of the upstream of the construction area, and real-time control at a mixed flow environment composed of the non-networked vehicles and the networked vehicles is achieved. Compared with the prior art, the method has the advantages of more comprehensive data, adaptability to different vehicle flows, better multi-dimensional vehicle road management and control effect and the like.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a roadside control system for a highway construction area in a vehicle-road coordination environment. Background technique [0002] With the gradual application of mobile Internet technology in the field of transportation, the resulting technologies such as the Internet of Vehicles and vehicle-road collaboration have advanced by leaps and bounds in the past decade, and have gradually moved from laboratories and test sites to practical applications, which have a profound impact on the transportation system. The vehicle-road collaboration technology realizes the Internet of Vehicles and the Internet of Vehicles, and applies mobile Internet technology to transportation. It is considered as the third technological revolution of transportation and is a current research hotspot. The main contradiction of the traffic control management problem lies in the imbalance, including the imbalanc...
