校车安全问题牵动着整个社会的稳定,因此,校车安全的行车路线的选择至关重要。致力于校车路线的制定(包括接送点的选取,以及车次、上车人数的分配)。具体方法是将影响行车安全的各种因素做量化处理,再通过调查统计,分配给各因素适当的比例,最后得出某一路段的危险参数——道路的权重,建立数学规划模型,并运用图论中的带全路径长度,Huffman树,拓扑排序(对其实施改良)等知识求解,得出不同路线分布(分为线形、树形以及图形路线)下的最优路径(安全路线)。最后以一个具体调研实例(新兴小学),对此方法进行验证,以求推广。
School bus safety issues affect the stability of society as a whole, therefore, school bus routing choice is essential. Committed to the development of school bus routes (including the selection of pick-up points, as well as trips, boarding the number of people assigned). Specific methods are to quantify the various factors that affect traffic safety, and then through the survey statistics, assigned to the appropriate proportion of the various factors, and finally come to the risk of a road parameters - the weight of the road, the establishment of mathematical programming model and use Graph theory with full path length, Huffman tree, topological sorting (to improve its implementation) and other knowledge to solve, come to the different routes (divided into line, tree and graphics route) the optimal path (safety route). Finally, with a specific research example (emerging primary school), this method is verified in order to promote.
