2014-2015 Puget Sound Regional Travel Study

The 2014-2015 Puget Sound Regional Travel Study collected information about household and individual travel patterns for residents throughout a four-county region in Washington State. Study results were used to update the region's travel and land-use models and to calibrate local traffic and travel models. The study also helped the Puget Sound Regional Council (PSRC) and its regional partners develop plans that accommodate the diverse travel needs and preferences of residents. The Resource Systems Group administered the study on behalf of PSRC. Global positioning system (GPS)-equipped smartphones were used to provide data pertaining to the daily travel of 547 individual participants. Because the region's university students may have been underrepresented in the initial 2014 household travel study, the PSRC added a college-population travel survey in fall 2014. In spring 2015, a second household data collection effort was conducted to increase the frequency of data collection and to collect GPS data as well as a sample of longitudinal data from households that completed the 2014 survey.2014-2015年普吉特湾区域出行研究（Puget Sound Regional Travel Study）针对华盛顿州四县区域内的全体居民，收集了家庭与个人出行行为模式的相关信息。该研究成果被用于更新该区域的出行与土地利用模型，并校准本地交通与出行模型。本研究同时助力普吉特湾区域委员会（Puget Sound Regional Council, PSRC）及其区域合作伙伴，制定适配居民多样化出行需求与偏好的规划方案。资源系统集团（Resource Systems Group）受PSRC委托执行本项研究。研究采用搭载全球定位系统（Global Positioning System, GPS）的智能手机，为547名参与个体的日常出行行为提供相关数据。鉴于初始2014年家庭出行研究对该区域内大学生群体的覆盖可能不足，PSRC于2014年秋季增设了大学生群体出行调查。2015年春季，研究团队开展了第二轮家庭数据采集工作，旨在提升数据采集频次，同时收集GPS数据，并对2014年参与调查的家庭开展纵向样本数据采集。
