Abstract

The invention provides a road control method for emergency evacuation of city transportation. The road control method comprises the following steps of S1, determining an evacuation request of a target transportation network; S2, according to the evacuation request and a network structure of the target transportation network, obtaining an optimum evacuation plan; S3, according to the optimum evacuation plan, generating a road control plan; S4, implementing the road control plan. The road control method for the emergency evacuation of the city transportation has the advantages that the lane turnover control is combined with the junction conflict releasing strategy, the direction selection in the evacuation process is simplified, and the whole evacuation efficiency of the network is improved; the management is convenient and rapid, and the evacuation efficiency is high.

Description

technical field [0001] The invention relates to the field of road traffic management, in particular to a road control method for urban traffic emergency evacuation. Background technique [0002] In cities, after a disaster or emergency occurs, traffic emergency evacuation plays a vital role in the evacuation of people in the disaster area and the rescue of emergency rescue vehicles. In particular, the evacuation of personnel in the disaster area pays attention to effectiveness. If the road control in the emergency state cannot be carried out timely and effectively, and a smooth emergency evacuation network can be established, the road will be blocked, people cannot be evacuated effectively, and loss of life and property will be caused. [0003] In order to implement traffic organization in an orderly manner and improve evacuation efficiency when emergencies occur, urban traffic managers need to make traffic emergency evacuation plans. Only by applying a reasonable and effe...
