高速公路交通应急救援资源的配置

针对交通事故与救援资源存在随机性的特点,建立了交通救援资源配置的随机模型。根据高速公路特有的道路条件与交通机理,确定了模型中救援服务水平、事故概率的权重,配置点至事故点的权值以及随机资源等参数值。将所建立的模型与参数用于河南省高速公路的救援资源配置,研究表明,新的配置方案较好满足了交通事故高概率区域的救援需求,并且合理减少了救援需求区域的资源配置数量,为目前高速公路交通应急资源的科学配置提供了重要的参考依据。

Allocation of Emergency Rescue Resources for Freeway Traffic

Allocating emergency rescue resources reasonably is the premises of improving efficiency. Aiming at the stochastic characteristic of traffic accident and required resources, a stochastic model for resource allocation is created. According to specific road condition and transportation mechanism, some parameters such as rescue service level, weight of accident probability, weight of rescue resource spot to accident spot and stochastic resources are discussed. The parameters and model are applied to rescue resources allocation of Henan freeway. The results show that the new allocation scheme preferably meets rescue demand of high-probability-accident area and reasonably reduces resources allocation numbers of low-probability-accident area. All of those offer important reference value for scientific allocation of emergency rescue traffic resources on freeway.
