A traffic guidance screen control system and method based on environmental information

Abstract

The invention discloses a traffic guidance screen control system and method based on environmental information, belonging to the technical field of vehicle-road coordination. The system includes: a road traffic environment cooperative perception module, a traffic management platform information interaction module, a data transmission operation efficiency analysis strategy module, a variable lane service coordination strategy module, and a traffic guidance screen control cloud platform; at the same time, the invention also provides an environment-based The information traffic guidance screen control method is used to specifically realize the relevant content of a traffic guidance screen control system based on environmental information. The present invention can realize intelligent networked vehicles and roads on the basis of traffic guidance screens based on traffic status and environmental information. The integrated application of traffic, the construction of predictive models, the improvement of the ability to deal with emergencies, the establishment of a lane change service policy mechanism, and the solution to the current security issues that are difficult to control when driverless cars change lanes.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination, in particular to a traffic guidance screen control system and method based on environmental information. Background technique [0002] The traffic guidance screen generally refers to a display screen made of LED light-emitting diodes, which is used to guide traffic. It is generally applied to expressways. The traffic guidance screen contains graphic guidance signs, which are composed of ordinary road signs and A multifunctional information display screen composed of variable information signs. [0003] The traffic guidance screen has obvious advantages such as intuitive display image, large amount of information, relatively short visual recognition time, and guiding drivers who are not familiar with road conditions. [0004] However, with today's technological level, unmanned driving, smart transportation and other fields are booming, and it is obviously difficult for a simple ...

Problems solved by technology

[0004] However, with today's technological level, unmanned driving, smart transportation and other fields are booming, and it is obviously difficult for a simple traffic guidance screen to meet the ever-changing life.

In the field of unmanned vehicles, how to use the traffic guidance screen to control, how to reduce the delay of network transmission, and ensure the timely release of instructions; how to control the lane change of unmanned vehicles and reduce the occurrence of safety risk accidents there is a huge gap
