Travel behavior is undergoing a period of significant change in the United States. In 2016, public transit ridership fell in almost all major U.S. metropolitan regions. While Americans are still heavily dependent on the personal automobile for mobility, technological and societal changes are transforming how mobility is accomplished. This paper reviews the convergence of five trends leading to fundamental changes in public transportation: (1) changing generational behavior toward suburbanization and automobility; (2) new attitudes toward information communications technology; (3) shifting attitudes toward sharing and mobility on demand; (4) innovative alternatives to work and non-work travel; and (5) an increasing number of on-demand flexible route transportation options. The paper concludes with recommendations and guiding principles for public agencies to consider in responding to these trends.

现在是公共交通复兴的时候了吗：在一个勇敢的新世界中应对旅行行为，技术和商业模式的转变

在美国，出行行为正经历着重大变化。2016年，美国几乎所有主要大都市地区的公共交通出行率都下降了。尽管美国人仍然严重依赖个人汽车的机动性，但技术和社会变革正在改变机动性的实现方式。本文回顾了导致公共交通发生根本变化的五种趋势的趋同：（1）将世代行为转变为郊区化和机动化；（2）对信息通信技术的新态度；（3）将态度转变为按需共享和流动；（4）工作和非工作旅行的创新选择；（5）越来越多的按需灵活路线运输选择。
