Abstract: In the course of researching highway emergency rescue system, the emergency resource scheduling method is the core of the emergency rescue system of the whole expressway. Aiming at the shortest end time of emergency rescue and the least cost related to emergency rescue, an emergency resource scheduling model based on the road capacity of construction area was established by using mathematical programming method, with the full consideration of the influence of expressway construction area on road section capacity, combining with the nature and characteristics of expressway construction area. The greedy algorithm was used to optimize the proposed model, and then to determine whether the emergency rescue points were involved in the rescue and the specific time and ability of participating in the rescue through the construction area. The cost-capability ratio of each rescue point was compared, so that the appropriate emergency rescue point could be selected for effective rescue. Taking the construction area of Jinan-Qinghai section of Shandong expressway as an example, the proposed model was empirically analyzed. The analysis results show that the application of the proposed model can reduce the rescue fee by 16.036 thousand yuan, which is 13.6% lower than the initial plan and reduces the rescue cost.

摘要： 在研究高速公路应急救援系统的过程中，应急资源调度方法是整个高速公路交通事件应急救援系统的核心。以应急救援结束时间最短和应急救援相 关费用最少为目标，充分考虑到高速公路施工区域对路段通行能力的影响，结合高速公路施工区域的性质和特点，采用数学规划的方法建立了基于施工区 通行能力的应急资源调度模型。通过贪婪算法对该模型进行优化求解，进而确定各应急出救点是否参与救援以及经过施工区参与救援的具体时间和能力， 对各个出救点的费用能力比进行比较，从而选择适当的应急出救点进行有效的救援，并以山东高速济青高速段施工区域为例对模型进行了实证分析。分析 结果表明：应用本模型的方案可以使救援费用减少16.036万元，相比降低了13.6%，缩减了救援成本。
