区域综合运输网络描述模型和构建系统是进行区域交通预测和网络规划的基础。通过对区域综合运输网络概念要素和系统数据构成的分析,在单项交通网路的基础上建立了多中心分层次的综合运输网络描述模型,并利用GIS技术探讨了多方式交通网络的构建方法。系统功能模块的设计可以提供一个可视化的交通网络编辑平台,实现了区域综合交通网络构建、网络图形和数据转换以及网络属性和社会经济数据的存储、修改、查询统计等功能。系统可以实时更新网络信息,为区域综合运输预测和网络规划提供准确完备的基础数据。
The regional integrated transport network description model and construction system are the basis for regional traffic prediction and network planning. Based on the analysis of the conceptual elements and system data of the regional integrated transport network, a multi-center hierarchical transport network description model is established on the basis of single transport network, and the construction method of multi-modal transport network is discussed by using GIS technology. The design of the system function module can provide a visual editing platform of traffic network and realize the functions of building comprehensive regional traffic network, converting network graphics and data, storing and modifying network attributes and socio-economic data. The system can update network information in real time and provide accurate and complete basic data for regional comprehensive transportation forecasting and network planning.
