2017 Puget Sound Regional Travel Study

# 2017 Puget Sound Regional Travel Study
The 2017 Puget Sound Regional Travel Study collected household- and person-level activity and travel pattern information from residents throughout the Puget Sound Regional Council's four-county region in Washington State.

It followed the [2014-2015 Puget Sound Regional Travel Study](https://www.nrel.gov/transportation/secure-transportation-data/tsdc-puget-sound-travel-study), starting a planned six-year data collection that includes 2019 and 2021. The multiyear program's goal is to maintain an updated source of household travel behavior data that:

- Supports modeling and planning needs
- Facilitates trend analysis over time
- Allows for regular study design updates to integrate evolving data collection methods and emerging travel behaviors and transportation issues.

## Data Collection Agency
The Puget Sound Regional Council conducted the study.

## Methodology
The 2017 study featured both the design and administration of a one-day household travel diary (approximately 80% of households before data cleaning) and a seven-day smartphone global positioning system (GPS) diary (approximately 20% of households before data cleaning). It combined data collection methods, including smartphone, online, and telephone. The survey design included several stages to recruit and collect data about households, their members, and their travel behaviors during the assigned travel period.

## Survey Records
Survey records include a total of 6,254 participants.

## More Information

## Transportation Data
The data set contains a demographic and socioeconomic composition of 6,254 people from 3,285 households in the Puget Sound regional area, as well as detailed information on the travel behavior of each household for a designated 24-hour period. The survey logged over 508 thousand vehicle miles of travel by participants during 52,492 trips.

# 2017年普吉特海湾区域出行研究（2017 Puget Sound Regional Travel Study）
2017年普吉特海湾区域出行研究从华盛顿州普吉特海湾区域委员会（Puget Sound Regional Council）所辖四县区域的居民中，收集了家庭与个人层面的活动及出行模式相关信息。

本研究接续[2014-2015年普吉特海湾区域出行研究（2014-2015 Puget Sound Regional Travel Study）](https://www.nrel.gov/transportation/secure-transportation-data/tsdc-puget-sound-travel-study)，启动了一项为期六年的规划化数据收集工作，覆盖2019年与2021年。该多年期项目的目标是维护一套更新的家庭出行行为数据源，具体可实现以下目标：
- 支撑建模与规划相关需求
- 助力长期趋势分析
- 支持定期更新研究设计，以融入不断演进的数据收集方法、新兴出行行为与交通议题。

## 数据收集机构
普吉特海湾区域委员会负责开展本项研究。

## 研究方法
2017年本研究采用了一日家庭出行日志（数据清洗前覆盖约80%的受访家庭）与七日智能手机全球定位系统（GPS, Global Positioning System）日志（数据清洗前覆盖约20%的受访家庭）的设计与实施。研究整合了智能手机、线上及电话等多种数据收集方式。调查设计包含多阶段流程，用于招募受访家庭并收集其成员在指定出行时段内的活动与出行行为相关数据。

## 调查记录
本次研究共收集到6254名参与者的有效记录。
