Optimization method and system for virtual and actual interactive traffic evacuation control scheme

Abstract

The invention discloses an optimization system for a virtual and actual interactive traffic evacuation control scheme. The system comprises a database, a model base, an actual traffic system, a virtual traffic system, a decision supporting platform and an evacuation scheme base, wherein the virtual traffic system synchronously interacts with the actual traffic system, so that parallel description of a traffic evacuation environment is realized; and the decision supporting platform comprises an evacuation scene generation module, a weather scene generation module, an evacuation scheme generation module and an evacuation result evaluation module and is used for finishing a traffic evacuation experiment function during a large activity, generating a traffic evacuation scene under normal and abnormal weather conditions and evaluating the an evacuation scheme effect. The optimization system supplies decision support to a traffic evacuation process through interaction between the virtual system and the actual system.

Description

technical field [0001] The invention belongs to the field of urban traffic control and management, and in particular relates to a traffic evacuation auxiliary decision-making support system for virtual and real interaction between a virtual traffic system and an actual traffic system. Background technique [0002] Urban traffic is a typical complex system, which covers a wide range and contains many contents. Its management and control are very difficult. The optimization of traffic evacuation control scheme is one of the representative problems. Traffic evacuation generally occurs during large-scale events or emergencies, where a large number of vehicles and pedestrians accumulate in a limited time and space, the traffic pressure is high, and abnormal events such as traffic accidents will have a serious impact on the evacuation process. Whether it can be successfully completed has a decisive influence on the activities. [0003] Generally speaking, the formulation and opti...
