Inducing device and inducing method of vehicle confluence at intersection based on vehicle and road collaboration

Abstract

The invention provides an inducing device and an inducing method of vehicle confluence at an intersection based on vehicle and road collaboration. The device consists of a video detector set, a roadbed computer module, a wireless router, a ring road side traffic information prompting screen and a traffic inducing band, wherein the video detector set is used for sending real-time collected video data of the vehicles on a high speed arterial road to the roadbed computer module; and the roadbed computer module is used for processing the video data to generate a control signal; and the control signal is sent to the ring road side traffic information prompting screen by the wireless router to respectively display and convert the modes of an LED lamp. The inducing method comprises the followingsteps of: obtaining the real-time speeds and real-time distances of the moving vehicles by processing the traffic video flow of the vehicles on the high speed arterial road; and generating the control signal, wherein the control signal is displayed by the traffic information prompting screen and is used for controlling the mode conversion of the LED lamps of the traffic inducing band. The invention is capable of effectively avoiding the traffic accidents on the intersection of the ring road and the high speed arterial road.

Description

technical field [0001] The invention relates to a traffic signal safety control technology in an intelligent traffic system, in particular to a vehicle-road coordination-based vehicle merging induction device at an intersection and an induction method thereof. Background technique [0002] With the rapid development of my country's urban material civilization, the average level of traffic flow on main roads and on-ramps of expressways has increased significantly, and the pressure on ground traffic has increased. The intersection of the main road and the ramp of the urban expressway is a place where potential moving vehicles conflict, and the traffic safety hazard is quite large. It is a location where traffic accidents occur frequently. The objective reasons for its existence are: on the one hand, the geographical conditions near the intersection are limited, On the other hand, due to the limitation of the geometric layout of the road design and the limitations of the traffi...

Problems solved by technology

The intersection of the main road and the ramp of the urban expressway is a place where potential moving vehicles conflict, and the traffic safety hazard is quite large. It is a location where traffic accidents occur frequently. The objective reasons for its existence are: on the one hand, the geographical conditions near the intersection are limited, On the other hand, due to the limitation of the geometric layout of the road design and the limitations of the traffic facilities, the driver driving from the ramp to the intersection and preparing to merge into the main road of the expressway cannot see the high-speed moving vehicles on the main road of the expressway, and cannot carry out reasonable planning. The speed control of the vehicle, the psychological pressure of driving is greater

At present, some relatively effective control methods for entrance ramp signals in China only provide speed limit signals in the form of traffic lights flashing, which can only awaken the driver's awareness of controlling the speed of the vehicle, but cannot avoid artificial subjective speed control errors; and , driving on the ramp, although the driver will consciously control the speed of the vehicle under normal circumstances, there is still a lot of psychological pressure to autonomously merge into the main road of the expressway
