Problems solved by technology

[0011] In the above technical solution, the image collector installed at the intersection is mainly used to collect video streams, and at the same time, the image collector is used to collect the license plate information of illegal vehicles. Since this method can only collect information about illegal vehicles near the intersection, the general range can only be within Within 30 meters, the adjustment angle of the pan/tilt only changes the monitoring target. Since the focal length of the lens is no

Embodiment Construction

[0055] This embodiment provides a monitoring system for expressway ramp intersections, including ground markings and a video monitoring system. The ground markings are as follows: image 3 shown, including:

[0056] Diversion belt: set on the No. 1 lane of the expressway at the downstream of the exit ramp, and vehicles are prohibited from entering;

[0057] No-parking zone: Set on the No. 1 and No. 2 lanes of the expressway at the entrance of the entrance ramp, vehicles are prohibited from parking;

[0058] Lane dividing line: set between adjacent lanes on the expressway, the solid line represents that vehicles are not allowed to cross, and the dotted line represents that vehicles are allowed to cross;

[0059] As a preferred embodiment, a dotted line is drawn on the right side of the lane line and on the left side of the no-stop zone, which means that vehicles can cross the line to the left;

[0060] As a preferred embodiment, the length of the solid line of the lane-dividi...

Abstract

The invention discloses a monitoring system and method for a freeway ramp mouth. The method comprises the following steps of: drawing a ground mark line and arranging a video monitoring system near an exit ramp of a freeway; presenting a solid line which indicates cross prohibition and a no-parking area which indicates parking prohibition, which are drawn on the freeway, by a video picture in a video detection unit in a virtual way; and when a vehicle which is drivn illegally is detected, shooting a picture on a vehicle license number of the vehicle which is driven illegally immediately by animage acquisition unit so as to be facilitate later discipline. The system plays a role of alarming so as to improve the traffic efficiency of the freeway ramp mouth.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, and in particular relates to a monitoring system and method for an expressway ramp crossing. Background technique [0002] With the rapid development of the city, the demand for traffic is increasing day by day. Road traffic congestion leads to an increase in people's travel time, which brings inconvenience to people's daily life and also restricts the development of the urban economy. In order to alleviate road traffic congestion and shorten people's travel time, large and medium-sized cities have built expressways accordingly. Vehicles enter or exit the expressway through the on-ramp and off-ramp provided on the expressway. During peak traffic times, vehicles need to line up to enter or exit the ramp. [0003] Such as figure 1 As shown, when an incoming vehicle enters the expressway through the ramp entrance, it needs to pass through the No. 1 lane to enter the No. 2 lane...
