Embodiment Construction

[0039] The present invention proposes an expressway vehicle guidance system and method based on vehicle type classification, aiming at making full use of the existing traffic infrastructure, simultaneously detecting vehicle density and average speed, analyzing the running state of the expressway, and judging different types of vehicles. The influence of vehicles on the running state of expressways provides data support and guidance for improving the traffic capacity of expressways. The core of the scheme is: use the surveillance cameras installed on the existing highway to collect video images of the area to be detected, use the video images to detect, track, and classify vehicles, calculate relevant parameters and perform congestion discrimination, when long-term congestion occurs, Guide a certain type of vehicle with a high proportion of some parameters.

Abstract

The invention provides an expressway vehicle guiding system and an expressway vehicle guiding method based on vehicle classification, aiming to fully utilize the present transportation infrastructure to analyze the running state of an expressway, judge the influence of different types of vehicles on the running state of the expressway and supply data support and guidance for increasing the traffic capacity of the expressway. The scheme core is as follows: collecting video images in a to-be-detected area by utilizing monitoring cameras installed on the present expressway, detecting, tracking and classifying the vehicles by utilizing the video images, calculating the total vehicle density, total average speed and density ratio of different types of vehicles, judging traffic jam and guiding the vehicles in higher vehicle density when the long-term traffic jam happens.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a system and method of expressway vehicle guidance based on vehicle type classification. Background technique [0002] Expressways play an important role in the transportation industry. In terms of design and construction, expressways adopt high technical standards and perfect transportation infrastructure, such as restricted access, divided lanes, dedicated vehicles, fully enclosed, and fully interchanged. Create conditions for the car to run quickly, safely, economically and comfortably. Compared with ordinary highways, expressways have outstanding advantages such as fast driving speed, large traffic capacity, low transportation cost, and driving safety. The traffic speed is more than 50% higher than that of ordinary highways, and the traffic capacity is increased by two to six times. , and can reduce fuel consumption by more than 30%, reduce vehicle...
