【摘要】：公路交通在新疆承担国家社会经济发展、“一带一路”建设和社会稳定等多方面战略保障任务中作用显著。新疆具有稀疏路网交通特性,路网分布密度低,交通事故急救基本依托公路实施,交通事故发生的时间、地点、规模以及人员伤亡情况都难以预测,可见其随机性和空间离散性特征明显,而急救资源分布密度低,且特殊气候、气象和路面条件对急救交通产生强干扰,调度技术滞后,效率低下。本研究通过对新疆公路交通特性、远程急救特性和急救能力、急救交通阻抗分析,建立急救资源的急救能力数模和急救交通阻抗数模,研发公路桩号坐标定位法和最佳急救资源及其最优路径选择方法,构建新疆公路急救量化调度系统。本系统以VB为开发工具,嵌入MapX加载新疆公路路网MapInfo图,并采用Access进行数据库管理应用,满足事故发生后急救资源的最佳调度及最优路径规划等功能。接警后,在新疆公路急救量化调度系统平台中应用桩号坐标定位法,输入道路名称和桩号,对事故点进行精准定位,根据事故等级,系统会迅速选择出最佳急救资源前往救援的最优路径方案,最大程度减少伤亡情况,并将经济损失降到最低。
[Abstract]:Highway traffic plays an important role in Xinjiang's undertaking of national social and economic development, the construction of "Belt and Road" and social stability, and so on. Xinjiang has the characteristics of sparse road network traffic, low distribution density of road network, and so on. Traffic accident emergency basically depends on the implementation of highway. The time, place, scale and casualties of traffic accident are difficult to predict. It can be seen that its randomness and spatial dispersion are obvious, but the distribution density of emergency resources is low. The special weather, weather and pavement conditions have strong interference to the first aid traffic, the dispatching technology is lagging behind, and the efficiency is low. This study analyzes the traffic characteristics, the characteristics of the remote first aid and the first-aid ability, and the traffic impedance of the first aid, through the analysis of the traffic characteristics of Xinjiang highway. The first aid capability model and traffic impedance model of first aid resources are established, and the coordinate positioning method of highway pile number and the method of selecting the best first aid resource and its optimal path are developed. This system takes VB as the development tool, embeds MapX to load the MapInfo map of Xinjiang highway network, and uses Access to manage the database. After receiving the alarm, the coordinate positioning method of pile number is applied in the platform of Xinjiang Highway Emergency quantitative Dispatch system, and the road name and pile number are input. According to the accident grade, the system will quickly select the best emergency resources to rescue the optimal path plan, minimize casualties, and reduce the economic losses to the minimum.
