Problems solved by technology

[0002] Complex traffic patterns include road conditions, road conditions and traffic flow status, emergencies, weather conditions and traffic control, etc. The detectors of smart vehicles cannot obtain all the above information, which can only be carried out within the effective detection range of the sensors. The perception of part of the information, which leads to the weakening of the vehicle's perception ability, so that it is impossible to avoid problems such as vehicle safety risks

Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] The control grid division method for complex traffic patterns under the vehicle-road coordination condition of the present invention includes the following steps:

[0018] S1. Establish a static simulation model of urban road traffic, which is used to describe the geometric characteristics of the road, lane divisions, widths of medians and road shoulders, road surface types, locations of fixed traffic signs, and locations of roadside units;

[0019] S2. In the vehicle-road collaborative environment, the traffic flow distribution model is measured through the real-time monitoring capability of the roadside unit, and is integrated into the static simulation model of u...

Abstract

The invention relates to the technical field of complex traffic control, in particular to a complex traffic form-oriented control grid division method under a vehicle-road cooperation condition. The method divides a road into control grids by using a boundary of communication transmission on the basis of a road side unit layout topology, so that the grids have road information perception capability and control capability, and real vehicle-road cooperative traffic control is formed. The method comprises the following steps: S1, establishing an urban road traffic static simulation model; S2, ina vehicle-road cooperation environment, performing operations by using the real-time monitoring capability of a road side unit; S3, performing operations in the urban road traffic dynamic simulation model in the step S2; S4, based on the urban road traffic dynamic simulation model, establishing a traffic information base; S5, applying, by a vehicle user, for a user node role; and S6, by a trafficinformation base, providing road traffic information for registered vehicle users.

Description

technical field [0001] The invention relates to the technical field of complex traffic control, in particular to a control grid division method for complex traffic forms under the condition of vehicle-road coordination. Background technique [0002] Complex traffic patterns include road conditions, road conditions and traffic flow status, emergencies, weather conditions and traffic control, etc. The detectors of smart vehicles cannot obtain all the above information, which can only be carried out within the effective detection range of the sensors. The perception of part of the information, which leads to the weakening of the vehicle's perception ability, so that it is impossible to avoid problems such as vehicle safety risks. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a control grid division method for complex traffic patterns under the condition of vehicle-road coordination. Based on the lay...
