Research Of Rescue Vehicles Service Point Location In Urban Road Traffic Accident Emergency Rescue

The rapid development of the city traffic not only greatly meet the demand of the social circulation of materials and personnel travel, but also brings about traffic jam, traffic accidents, worse traffic environment etc. Considering the city traffic safety issues, We discuss the main characteristics of the city road traffic accidents, the rescue system connotation, the principles of the rescue management, and the city road traffic accident rescue vehicles system operation process. Also, we analyze the problems of the existing vehicle rescue system and the rescue vehicles facility location status.In the study of the city road traffic accident rescue vehicles system, we need to analyze the relationships of the models in the complex rescue system. Since the grid management can ensure that the complex system has an aggregate, information integration, resource sharing and collaborative features such as operation, we introduce the grid management thinking into the vehicle rescue system, grade the vehicles rescue upon the current status of the vehicle rescue, build the corresponding traffic accident emergency rescue response. Upon this, we build a city road traffic accident rescue vehicles management system, which opens up a new route in the city vehicle road traffic accident emergency rescue work.In the city road traffic accident rescue service vehicle location, location decision model to traffic after the accident the improvement of emergency rescue response speed and ability to rescue, prevention of two accidents, reduce accidents caused by the economic loss and as a result of the accident caused traffic jams, achieve the rescue resources comprehensive benefit maximum. The city vehicle road traffic accident rescue facility location model, such as the cover model, condition coverage model, backup coverage model and P-Median Problem and P center problems of. Based on the rescue service location of guiding ideology and principle, combine Guangzhou city road traffic accident rescue vehicles resource layout of the actual needs, considering the location involves economy, efficiency, equity and the environment and many other factors, set up to meet the actual needs of the multiple objective decision model for location selection. And from the weighted method, constraint method and simulated annealing method to the solution of multi-objective model has carried on the preliminary discussion and analysis.Finally, this paper takes Guangzhou city road traffic accident rescue vehicles as the background, studies the multiple objective decision model for the vehicle rescue location selection, and proves the effectiveness of the target site selection decision.
