| 摘 要： | 区域交通系统是一耗散结构。基于交通系统的特性,选择区域交通网络有效路段上的平均交通拥挤度为序参量,来描述区域交通系统的演化过程和方向。通过分析区域交通系统的耗散结构属性,利用熵理论和信息论,建立了区域交通系统熵测算模型,并利用该模型对1998￣2004年间北京都市圈交通系统熵进行了实证性测算研究,并根据熵变理论,对该区域内交通系统演化过程及方向作出分析。

| Abstract: | Regional transportation system is a dissipative structure.Based on the properties of transportation system,effective road section average traffic congestion degree is used as a sequential parameter to describe the process and direction of system evolution.After analyzing the dissipative structure property of the transportation system,an entropy measuring model is put forward based on entropy theory and information theory.Finally,transportation system entropy in Beijing Metropolitan Area from 1998 to 2004 is calculated according to the model,and the process and direction of system evolution is analyzed based on entropy change theory. |
