摘要
城市交通系统正逐渐由原来的单一模式转变为相互连通的多模式,为了更准确地表达多模式交通网络系统,并满足个人出行时路线规划和时间预测的要求,该文以Oracle空间网络数据模型为建模基础,以武汉市为例,选取了道路网、公交路网和地铁路网三种路网模式构建了多模式交通路网,并且加入公交线路和地铁线路的时刻表因素,旨在使出行者通过该模型可以找到到达目的地的最快路线并预估该路线所需时间.
The urban traffic system is gradually changing from a single mode to interconnected multi-mode. In order to express the multi-mode traffic network system more accurately and meet the requirements of personal route planning and time prediction, this paper selects Oracle spatial network data model as the modeling foundation. The model takes Wuhan City as an example, and selects the road network, bus network and railway network to construct a multi-mode traffic network. Also the schedule of bus lines and subway lines is added to allow the travelers to find the quickest path to destination and to estimate the time required for the route.
