| 摘 要： | 在分析平衡配流模型交通系统假设的基础上,讨论了连续型交通分析模型的建模方法,分析了其主要特点、发展过程,并给出了单一吸引点模型的基本数学模型公式.作为区域交通分析中较为新颖的建模方法,连续型交通分析模型将区域交通系统抽象为平面二维空间体系,并假设属性函数可以用光滑的连续函数来表示.应用研究表明连续型交通分析模型在大范围、全局性的交通规划、控制管理以及物流分析中有着良好的前景.

| Abstract: | Based on analysis of transportation system hypotheses for traffic equilibrium assignment model,this paper discusses the modeling method for continuous traffic analysis model and introduces its main characteristics and development process.The basic mathematic modeling method for single attraction point is given.The plane based continuous traffic analysis model is a new approach for regional transportation analysis.The major assumption of this modeling method is that the regional transport system can be regard as planar system and hence the characteristics of the network can be represented by smooth mathematical functions.Its application research demonstrates that it is an efficient method for large scale transportation planning,traffic control and logistic analysis. |
