Problems solved by technology

Due to the different speeds of these three lanes, it is very important to guide the wrong-way vehicle back to the correct dedicated lane safely without affecting other normal vehicles in the lane, but there is little research in this area in the prior art

Embodiment 1

[0056] Such as figure 1 As shown, the present embodiment provides a method for guiding wrong-way vehicles on a passenger-cargo separation expressway, including the following steps:

[0057] S1: Determine whether there is a wrong-driving vehicle on the expressway. In actual use, it is possible to detect whether there is a wrong-driving vehicle through a video detector or a camera.

[0058] S2: If there is an erroneous vehicle, then guide the erroneous vehicle to enter the ramp (the ramp of the special interchange), and detect whether there is a vehicle on the outermost correct lane within the preset range of the ramp exit.

[0059] In this step, guiding the wrong-way vehicle to enter the ramp can be guided by the following methods:

[0060] In the upstream direction of the ramp entrance, the distance from the ramp entrance L 1 Set the first guide sign at the place to guide the wrong-way vehicle to change lanes so as to enter the ramp.

[0061] V 1 and the normal driving sp...

Embodiment 2

[0083] Such as image 3 As shown, the present embodiment provides a system for guiding wrong-way vehicles on highways separated from passengers and goods, including:

[0084] Judging the wrong-way vehicle module 1, used to judge whether there is a wrong-way vehicle on the expressway;

[0085] The guidance detection module 2 is used to guide the wrong-way vehicle to enter the ramp if there is a wrong-way vehicle, and detect whether there is a vehicle on the outermost correct lane within the preset range of the ramp exit.

[0086] Guide detection module 2 may further include:

[0087] Guidance into the ramp sub-module, used in the upstream direction of the ramp entrance, the distance from the ramp entrance is L 1 Set up the first guide board at the place to guide the wrong-way vehicles to change lanes so as to enter the ramp;

[0088] L 1 ≥ V 2 ...

Abstract

The present invention provides a method and system for guiding vehicles driving in a wrong way on a passenger car and truck separating highway. The method and system for guiding vehicles driving in the wrong way on the passenger car and truck separating highway are configured to determine whether there are provided vehicles driving in the wrong way on the passenger car and truck separating highway. If there is provided a vehicle driving in the wrong way, the vehicle driving in the wrong way may be guided to drive into a ramp, and it is detected whether there is provided a vehicle driving on an outermost driveway in the preset range of the ramp exit. If there is provided a vehicle driving on the outermost driveway, the vehicle driving in the wrong way may be guided to park at a first preset position in the ramp for waiting, and at the same time the vehicle driving on the outermost driveway may be guided to another driveway, then the vehicle driving in the wrong way may be guided to drive on a correct driveway through the ramp exit after the vehicle driving on the outermost driveway is changed to another driveway; and if there is not provided a vehicle driving on the outermost driveway, the vehicle driving in the wrong way may be guided to drive in a correct driveway through the ramp exit. The method and system for guiding vehicles driving in wrong way on passenger car and truck separating highway are applicable to the guidance of vehicles driving in a wrong way to return back to a correct driveway through an accommodation overpass bridge, the guidance of the vehicles driving in a wrong way to park in the first preset position in the ramp, and the guidance of vehicles driving on the outermost driveway to change ways, so that the vehicles driving in the wrong way may safely return back to the correct accommodation lane through the accommodation overpass bridge and cannot influence other vehicles driving in the lane.

Description

technical field [0001] The invention relates to the field of expressway traffic management, in particular to a method and system for guiding wrong-way vehicles on expressway with passenger and cargo separated. Background technique [0002] According to its organizational form, expressways can be divided into: passenger-cargo mixed expressway and passenger-freight separated expressway. The traditional passenger-cargo mixed expressway has a series of traffic safety and traffic efficiency problems due to the large speed dispersion between passenger cars and trucks and the performance differences between passenger cars and trucks. Passenger-cargo separated expressway adopts a separated section form to realize passenger cars and trucks running on separate lanes, which can greatly improve road traffic capacity, and also reduce traffic caused by large speed dispersion and frequent lane changes. The accident ensures the safety of the vehicle. [0003] Due to the fact that during t...
