Highway entrance ramp heterogeneous traffic flow vehicle speed guiding system and guiding method

Abstract

The invention provides a highway entrance ramp heterogeneous traffic flow vehicle speed guiding system and guiding method, and the guiding system comprises: an intelligent vehicle-mounted subsystem which is used for obtaining the vehicle information of an intelligent vehicle, and is installed on the intelligent vehicle; the network connection vehicle-mounted subsystem that is used for acquiring network connection vehicle information, and the network connection vehicle-mounted subsystem is installed on a network connection vehicle; the common vehicle information acquisition subsystem that is used for acquiring vehicle information of a common vehicle and is mounted on a road side; the intelligent vehicle-mounted subsystem, the network connected vehicle-mounted subsystem and the common vehicle information acquisition subsystem are wirelessly connected with the roadside speed decision subsystem. According to the highway entrance ramp heterogeneous traffic flow vehicle speed guiding system,a guiding system capable of rapidly achieving highway entrance ramp vehicle guiding is provided, different subsystems are utilized for different vehicles, and the problem that vehicle congestion is likely to happen at a ramp entrance is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a vehicle speed guidance system and a guidance method for a heterogeneous traffic flow on an entrance ramp of an expressway. Background technique [0002] Accidents and congestion on highway on-ramps are on the rise as car ownership explodes. At the same time, with the development of intelligent network connection technology, vehicles with different degrees of intelligent network connection will appear in road traffic one after another. In the future, there will be a long-term phenomenon of heterogeneous traffic flow mixed on the road. [0003] The development of intelligent network technology can realize the precise control of individual vehicles, which provides an opportunity for speed guidance to control traffic congestion. Speed ​​guidance has the advantages of taking into account efficiency and safety, and has obvious governance effects. In th...
