Abstract: Based on the Demand Responsive Transit System (DRTS) theory , the characteristics of small and medium-sized cities' requirements about DRTS were researched through studying the practical cases in western countries. According to the method of analogy and comparison , the best operation mode of the bus and elastic route plan was selected , at the premise of meeting the demands of passengers. The DRTS development data in Yunfu city , in Guang Dong province were taken as the research object. The results show that DRTS can reduce passengers' costs and let the operation costs be less than the traditional model. 8ased on the reasonable use of DRTS , the effective mode in remote areas in small and medium-sized cities should be focused on. The proposed theory provides a new idea for the development of urban-rural public traffic integration which suits the local practical conditions.

Key words: demand responsive transit system (DRTS), method of analogy, bus lines, remote areas

摘要： 基于需求响应式运输系统(DRTS)的概念，通过对西方国家的实际案例的学习，研究适合推行DRTS的中小型 城市服务区域的需求特性。根据类比与对比法，提出在满足乘客需求的前提下，选择公交的最佳运营模式和弹性路 线方案。以广东省云浮市部分地区为例，探讨DRTS在当地区域的发展。研究结果表明:该运营模式可降低乘客出 行成本，且较传统公交模式而言节约运营成本;在合理运用DRTS的基础上，应着重研究中小型城市偏远地区实施 的有效形式，并基于该理念为寻找适应当地实际情况的城乡客运公交一体化发展提供了新思路。
