摘　　要：现代城市的公共交通系统已由原有的巴士系统,向巴士和轨道交通共同构成的新型复合交通系统转变,为了这种复合系统的有效管理,并方便市民出行规划等应用,需要构建相应的空间数据模型。本文提出了一种复合公交空间数据模型,分别对城市道路网络、公交巴士站点和路线、地铁站点和路线进行了空间建模,并给出了基于数据模型重构巴士系统和铁路系统网络模型的算法。The public transportation system of modern cities is converting from a single mode marked as the bus system to a comprehensive manner that comprises the high-speed transportation system represented as the urban railway system additionally. For the management of such comprehensive public transportation system and the achievement of planning traveling routes for residents, an appropriate spatial data model is needed. This research gives a design for such model, which include urban street network, the fundamental elements of the public bus system which are bus stop and route, and the critical parts of the urban railway system including railway stop, route and transfer entrance. Also, an algorithm is developed to reconstruct the network models of the public bus system and railway system.
