Embodiment Construction

[0033] This patent adopts a semi-enclosed construction scene. Taking the current common two-lane road as an example, one lane is closed for construction and the other lane is used for traffic control strategy design. This choice can better illustrate the effectiveness of this patent.

[0034] The traffic coordination control in the construction area described in this patent is realized in the vehicle-road and vehicle-vehicle communication environment. Roadside equipment supporting positioning and vehicle-road communication functions is installed at the entrance of the construction area, and vehicle-mounted terminals with positioning and vehicle-vehicle and vehicle-road communication functions are installed on vehicles. The communication range is 1000 meters and the frequency is 10 times per second. The prerequisite for the realization of this method is to assume that the driver adjusts the driving behavior strictly according to the instructions of the vehicle terminal, such as ...

Abstract

The invention discloses an expressway construction area traffic flow coordination control method based on vehicle-road and vehicle-vehicle communication. In the method, the vehicle-vehicle and vehicle-road communication technology is adopted, wherein the front road construction and traffic state information is transmitted and exchanged between the construction area and the vehicle and between the vehicles; the vehicle calculates and predicts possible safety conflict and interference during lane change and confluence of vehicles in front of the construction area according to the information; and an optimal traffic flow coordination control policy is obtained through calculation, and the driver is warned and prompted through sound or text to adjust the driving behavior of the vehicle in advance so that the vehicles mutually cooperate to realize lane change and confluence early, the road passing efficiency is improved, and the probability of accidental congestion is reduced. The method is also applicable to the traffic flow coordination control in the case of lane closing caused by traffic accidents. The method also can be combined with an automatic vehicle, and the vehicle driving behavior is automatically controlled according to the calculation result.

Description

technical field [0001] The invention belongs to the field of traffic safety services, and relates to a method for coordinating traffic control in expressway construction areas based on vehicle-road and vehicle-vehicle communication technologies, so as to improve traffic efficiency and safety in construction areas. The present invention is also applicable to traffic coordination control in the case of partial lane closure caused by traffic accidents. Background technique [0002] With the continuous increase in the mileage of expressways in my country and the rapid growth of traffic volume, expressway maintenance, upgrading and expansion projects are becoming increasingly arduous. In the process of expressway maintenance and construction, some lanes are closed, but the traffic is not interrupted. Therefore, it is very easy to cause the deterioration of the vehicle operating environment in the highway construction work area, accidents, congestion, etc., thus improving the driv...
