Abstract
The invention discloses a discrimination system for illegal occupation of an emergency lane of a highway, which comprises a detection section, an upstream collector, a downstream collector, a memory, a central processing unit and a downstream information display screen. The central processing unit can calculate the travel speed of the vehicle passing through the detection road section and the sequencing variation of the entering and exiting of the detection road section under the condition that the detection road section is in the creep according to the acquisition information of the acquisition unit in the memory. When the travel speed and the sequencing variation of the vehicle exceed the threshold values, the vehicle is judged to have suspicion of illegally occupying the emergency lane in the range of the detected road section. After the suspected vehicle is eliminated as an emergency vehicle, the illegal action of the vehicle is warned on a downstream information display screen. The invention is helpful for guaranteeing the traffic order of the expressway.
Description
Technical Field
The invention belongs to the technical field of expressway traffic control, and particularly relates to a discrimination system for illegal occupation of an expressway emergency lane.
