Research On Highway Emergency Dispatch And Vehicle Shunt Method Under Sudden Accident

With the rapid development of China's expressway,more and more vehicles into the highway,while the highway traffic speed is relatively fast,leading to frequent accidents,and the consequences of the accident is extremely serious.This type of accident is generally the degree of damage to ordinary road traffic several times,and even a few times,not only endanger the highway vehicle occupants of life and property safety,but also on the highway road production serious harm.Traffic accidents usually lead to traffic congestion,in the highway traffic accidents,not only endanger the safety of public and private property,but also cause road congestion,the normal operation of the highway traffic caused serious impact,and even lead to road traffic paralysis.Therefore,the emergency rescue and protection of the highway will become very important.This paper focuses on the study of expressway emergency resource allocation,emergency vehicle dispatching and expressway vehicle diversion under the sudden accident,and the concrete work is as follows:(1)Analyzed the emergency situation under the sudden traffic accident,summed up the characteristics of the expressway emergency rescue under the sudden accident,and constructed the emergency allocation model of the expressway based on the comprehensive cost,which mainly considered the emergency The actual purchase and storage costs of resources,and according to the different rescue points of the level of rescue services and the actual capacity of emergency resources to configure the rescue point of the higher level of rescue services,the greater the capacity,the more configurable emergency resources.At the same time,the model also takes into account the idle cost.Due to the historical data of the accident,the probability of the accident is summed up,which has certain reference value for the advance configuration.Finally,based on the application background of Heze surrounding highway network,based on the simulation of the accident and rescue needs,the application of genetic algorithm to solve the simulation verification.(2)Aiming at the sudden traffic accident,such as general traffic accident and dangerous product accident,this paper puts forward the emergency vehicle dispatching method of expressway,and puts forward a kind of emergency vehicle dispatching method based on the rescue response time,Direct cost of emergency vehicle scheduling method,and to Shandong high speed Heze around the highway network to verify the example.(3)From the micro and macro levels to study the highway traffic diversification method under the sudden accident,including: sudden accident under the highway section of the shunt method,sudden accident highway road network diversion method.
