题目:A GIS-BASED DECISION SUPPORT SYSTEM FOR ANALYSIS OF ROUTE CHOICE IN CONGESTED URBAN ROAD NETWORKS
作者:Yi-Hwa Wu,Harvey J. Miller,Ming-Chih Hung
Abstract: Urban congestion patterns have become ubiquitous and complex. Traditional,“static” approaches are no longer adequate for analyzing network flows and conducting minimum cost routing. This paper reports on a GIS-based decision support tool for modeling dynamic network congestion and conducting minimum cost routing. The system predicts network flows at a detailed level of temporal resolution, capturing dynamic congestion propagation effects. A Route Planner module solves for the combined departure time and minimum cost routing required for a trip to reach its
destination by a given deadline. The GIS provides effective decision support through its database management capabilities, graphical user interfaces and cartographic visualization. This supports analyses of "what-if?" scenarios for strategic planning and tactical management subject to unplanned network disturbances.
文中的Literature Review倒是可以简单明了的了解很多城市交通网络平衡和非平衡分析发展直至DTA的进城!
不管是GIS的,切合实际的引入GIS工具进行交通网络拥挤的动态数学建模,以及实现用户最优的目标,这里用dynamic user optimal (DUO)这样的目标来加以描述。
值得花点时间阅读!
