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] in,
[0089] V 1 : The normal driving speed of the wrong-way vehicle on the wrong lane;
[0090] V 2 : The normal driving speed of the wr...

Abstract
The present invention provides a method and system for guiding wrong-way vehicles on expressway with separated passenger and cargo. By judging whether there are wrong-way vehicles on the expressway; Whether there is a driving vehicle on the outermost correct lane within the preset range; if there is a driving vehicle, guide the wrong vehicle to stop and wait at the first preset position in the ramp. At the same time, guide the driving vehicle to change lanes. After the driving vehicle completes the lane change Guide the wrong-way vehicle to enter the correct lane through the ramp exit; if there is no driving vehicle, guide the wrong-way vehicle to enter the correct lane through the ramp exit. The method and system are suitable for guiding the wrong-way vehicle to return to the correct lane through the special interchange, by guiding the wrong-way vehicle to stop and wait at the first preset position in the ramp, and at the same time guiding the driving vehicle to change lanes, it is ensured that the wrong-way vehicle passes through the special overpass. The overpass safely returns to the correct dedicated lane without affecting other normal vehicles 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...
