A method for establishing a risk avoidance transfer model for flood diversion areas under passive flood diversion scenarios

Abstract

The invention discloses a flood-diversion area danger-avoiding transfer scheme programming method in a passive flood-diversion scene, and belongs to the technical field of disaster danger-avoiding scheduling plans and applicable countermeasure studies thereof. The flood-diversion area danger-avoiding transfer scheme programming method comprises the steps of: generating a danger-avoiding transfer original static feasible route table; evaluating cost of personnel transfer; evaluating a danger-avoiding transfer scheme based on a time window; establishing a danger-avoiding transfer model in the passive flood-diversion scene; and solving the danger-avoiding transfer model. The flood-diversion area danger-avoiding transfer scheme programming method gives full consideration to the influence of the flood routing process on the danger-avoiding transfer process and road congestion situation in the transfer process, the provided time window concept realizes organic combination of the danger-avoiding transfer model and the influence of the flood routing process as well as the road congestion situation, and accurately describes the personnel transfer process in the passive flood-diversion scene; meanwhile, the method provides a danger-avoiding transfer cost evaluation function based on road congestion coefficient for the defects of the traditional method in the aspect of personnel transfer cost, and achieves the scientific quantization of the personnel transfer cost.

Description

technical field [0001] The invention belongs to the technical field of disaster avoidance scheduling, and more specifically relates to a method for establishing a risk avoidance transfer model in a flood diversion area under a passive flood diversion scenario. Background technique [0002] The formulation of the risk avoidance and transfer plan for flood victims in the flood diversion area is a necessary non-engineering disaster prevention and mitigation measure, which combines the natural laws of flood disasters with the human response process, and uses the The system analysis method and computer simulation technology work out the best risk avoidance and transfer plan, which provides a scientific basis for decision-making and planning of flood fighting and disaster relief. The purpose of flood avoidance is to find the best evacuation route for people to be transferred to the disaster relief point. At present, the Dijkstra shortest path search algorithm is mostly used, but i...

Problems solved by technology

[0003] In view of the above defects or improvement needs of the prior art, the present invention provides a method for establishing a risk avoidance transfer model in a flood diversion area under a passive flood diversion scenario. The impact of traffic flow, vehicle speed, and density on road congestion is not considered. The road resistance value is not accurately quantified, so that the transfer path obtained based on it is not an optimal technical problem.
