Abstract

The invention discloses a lane management method based on traffic flow in an intelligent traffic system, and the invention discloses a management control system for left turn and straight lane number of an intelligent traffic intersection. There are three lanes for left-turn, straight-run and right-turn in a larger intersection, wherein the right-turn lane may have a right-turn dedicated light to control the traffic of the vehicle, and the right-turn lane may have a right-turn of the vehicle. Therefore, there is typically a fixed number of lanes to turn right at the intersection. However, left-turn and straight-run lanes in a large intersection have respective traffic flows due to the mutually independent traffic flows, and the straight-run lane is released to cause straight-run vehicles of opposite lanes to pass through, so that the left-turn vehicles cannot turn left under the influence of the passing of the opposite straight-run lanes, and the left-turn and straight-run lanes do not commonly share the lanes in the large intersection. In the case of a limited number of lanes, how to allocate the limited number of lanes between left-turn and straight-run lanes is a critical issue to be resolved urgently in the decision-making of a variable lane in an intelligent traffic system. In order to solve the problems, a lane management method based on traffic flow in an intelligent traffic system is provided, and deep theoretical analysis and application exploration are performed, so that a unique and efficient solution is provided. Physically fit the context of real-world applications and will be able to be effectively applied to engineering practices.

Description

Lane management method based on traffic flow in intelligent traffic system Technical Field The invention relates to an intelligent traffic control method, in particular to a lane management method based on traffic flow in an intelligent traffic system. Background The variable lane technology in intelligent traffic is an innovative traffic management means and aims to cope with increasingly complex flow changes in urban traffic. With the acceleration of the urban process, part of road sections are crowded with traffic flow in peak time periods but have limited lane resources, and the difference of the traffic flow in the peaks in the morning and evening is obvious, so-called tidal phenomenon is formed. To alleviate this problem, variable lane technologies have evolved. The variable lane, also called as intelligent lane or tide lane, features that the running direction of the lane can be regulated flexibly based on the real-time traffic flow. By arranging a plurality of oblique lines on the inner side of the lane and providing the LED electronic indication board, the traffic management department can monitor in real time and intelligently adjust the lane function according to the dynamic change of the flow direction of the vehicle, thereby optimizing the utilization efficiency of road resources and effectively relieving traffic jam pressure. The wide application of the technology not only improves the road passing efficiency, but also brings more intelligent and humanized solutions for urban traffic management.
