Method for determining highway lane management and control strategy based on congested road section

Abstract

The invention discloses a method for determining an expressway lane management and control strategy based on a congested road section. The method comprises the steps: collecting traffic data through an expressway detector, and converting the queuing length into the traffic volume per unit hour; under the condition that the sum of the actual traffic capacity per unit hour of the congested road section and the traffic volume per unit hour converted from the queuing length cannot exceed the actual traffic capacity per unit hour of the downstream area, determining the saturation value of emergency lane opening of the congested road section; and determining an emergency lane opening end point according to whether the remaining unit hour traffic capacity of the downstream area under the condition that the emergency lane is not opened can meet the unit hour traffic volume of the emergency lane, and further determining the emergency lane opening length. According to the method, the vehicles in the congested road section can be timely dissipated, the highway traffic efficiency is improved, the open length of the emergency lane is reasonably determined, the waste of emergency resources caused by opening the emergency lane for a too long distance is avoided, and a scientific decision-making method is provided for opening the emergency lane to solve the traffic congestion problem.

Description

technical field [0001] The invention relates to the field of expressway management strategies, in particular to a method for determining expressway lane control strategies based on congested sections. Background technique [0002] With the development of the economy, the demand for traffic is growing rapidly, and traffic congestion occurs frequently, not only in the urban traffic during the daily rush hour, but also in the expressways with high traffic capacity and efficiency. In order to alleviate traffic congestion, the expressway management department has adopted more control measures, such as speed limit, route guidance, ramp control, etc., all of which have achieved the effect of relieving traffic congestion to a certain extent, but these control measures cannot reduce the number of travelers. There is a strong need to choose convenient passages for efficient travel, so it is necessary to adopt the strategy of temporarily opening emergency lanes to improve traffic capac...
