Regional emergency traffic evacuation simulation system based on activity

Abstract

The invention discloses a large-scale regional emergency traffic evacuation simulation system based on activities, which comprises a disaster evolution module, a road network construction module, a population and activity generation module, a microscopic traffic simulation module, an animation display module and a statistical analysis module. The disaster evolution module is used for providing an influence of a disaster on a road system; the road network construction module is used for constructing a road network and an activity place; the population and activity generation module is used for generating a population evacuation and individual and family escape plan; the microscopic traffic simulation module is used for generating a population evacuation and vehicle movement trajectory; the animation display module is used for displaying a population evacuation and vehicle movement process; and the statistical analysis module is used for statistical analysis of traffic conditions during evacuation. The individual and family escape plan and the destructive effects of disasters on the road network during evacuation are comprehensively considered, the vehicle movement process is described via microscopic traffic simulation, the whole traffic evacuation simulation process is enabled to be more practical, and the assessment of an emergency traffic evacuation plan can be realized effectively.

Description

technical field [0001] The invention relates to the technical field of regional large-scale emergency traffic evacuation, in particular to an activity-based regional emergency traffic evacuation system. Background technique [0002] Emergency traffic evacuation is an important means for many countries in the world to deal with natural or man-made disasters. Carrying out emergency traffic evacuation with the help of a large-scale emergency traffic evacuation simulation system is of great significance for scientifically formulating reasonable and efficient emergency traffic evacuation plans and improving the city's ability to deal with emergencies. [0003] Although traditional simulation systems can be applied to emergency traffic evacuation, because these systems only consider normal traffic behavior, they cannot reflect the complexity of emergency traffic evacuation well, and the simulation results are far from the actual ones. The existing simulation system for emergency ...

AI Technical Summary

Problems solved by technology

[0003] Although traditional simulation systems can be applied to emergency traffic evacuation work, because these systems only consider normal traffic behavior, they cannot reflect the complexity of emergency traffic evacuation well, and the simulation results are far from the actual situation.

The existing simulation system for emergency traffic evacuation partially considers the traffic behavior in emergency situations, but does not consider the decision-making behavior and activities of individuals and families, and the simulation results are far from the actual situation
