基于可拓理论的城市主体公交模式双层决策模型

Bi-level Decision-making Model of Urban Transit Mode Selection Based on Extension Theory

城市主体公交模式选择是构建城市公共交通系统的重要工作内容,文章运用可拓理论,选择影响城市公共交通发展的5种主要模式:地铁、轻轨、BRT、使用公交专用道的常规公交和限制小汽车增加公交运力,遵循客观、易操作的原则,构建城市公共交通方式选择的可拓决策模型与协调度评价模型,并给出决策选择的具体实施步骤。

The urban transit mode selection is one of the important tasks of urban public transport system construction. In this paper, the extension theory was applied to select the five main urban transit modes： subway, light rail, BRT, the use of bus lanes, and increase of public transport capacity while the car is limited. Based on the principle of practicability and feasibility, the extension decision making model and coordination model for urban transit selection were built. Furthermore, the main implementation steps for decision-making were given.
