Early warning method for illegal parking of key operating vehicles on expressway

Abstract

The invention provides an early warning method for illegal parking on the highway of a key operating vehicle. The early warning method comprises the steps that geographical mathematical modeling of a parking area on the target highway is performed so that a parking area geographical mathematical model of the target highway is obtained; driving speed of the key operating vehicle and driving distance between two continuous locating points of the key operating vehicle are calculated according to real-time locating information of the key operating vehicle; whether the key operating vehicle is in the parking state is judged according to driving speed and distance, a preset speed threshold and a preset distance threshold; if the key operating vehicle is in the parking state, parking start time is recorded, and whether the key operating vehicle is parked in the parking area on the target highway is judged through combination of the geographical mathematical model; when the key operating vehicle is not parked in the parking area, congestion of the current road section in which the key operating vehicle is located is judged; and alarm information is generated when the current road section in which the key operating vehicle is located is not congested.

Description

technical field [0001] The present invention relates to the vehicle location information acquired by the Global Navigation Satellite System (GNSS), which is used to provide early warning of the parking positions of key operating vehicles, and especially relates to a method for illegal parking of key operating vehicles driving on expressways. early warning method. Background technique [0002] Key operating vehicles include passenger vehicles used for road operations, dangerous goods transport vehicles, semi-trailer tractors, and heavy-duty trucks (ordinary cargo vehicles with a total mass of 12 tons and above). [0003] Compared with illegal parking on ordinary roads, illegal parking on expressways is more dangerous. On the expressway, due to the fast driving speed of the vehicle and the short reaction time of people, the driver of the rear car often has no time to take measures when he finds the stationary vehicle in front, which can easily lead to traffic accidents.

Problems solved by technology

At present, highway supervision mainly uses manual patrols and surveillance cameras to detect illegal parking situations. Both of these methods have regulatory blind spots and lack a systematic automated monitoring method.
