四阶段交通预测模型基础数据库设计

Database Design for Four-Step Traffic Forecast Model

基础数据是交通模型的根本,一个好的基础数据库也是交通模型可靠性的有力保障。本文分析了建立四阶段交通规划模型的数据需求,并对其来源进行了分析,提出了最基本的交通模型数据库结构。

Basic data is the root of macroscopical transport model, and a perfect basic database is also the forceful guarantee of model＇s reliability. This paper discusses the data demand for Four-step Model and analyzes its data sources, then give the basic data structure of transport model
