Puget Sound Regional Household Travel Survey - Trips

This dataset is the 2017 Puget Sound Regional Travel Survey (PSRC household survey), which collected detailed trip information and sociodemographic characteristics from 6,254 individuals in 3,285 households living in the central Puget Sound (Seattle, WA) region (Puget Sound Regional Council, 2018). In 2017, the central Puget Sound region had a population of 4,063,700 with a density of 591 people per square mile, which is comparable to other metropolitan areas, such as Boston or Houston (American Community Survey 2017). Covering 0.20 percent of households and 0.16 percent of the population in the region, the survey used a geographically proportional sampling plan based on the household distribution in each census block group, and oversampled population segments that are traditionally difficult to reach, such as transit users and pedestrians (Puget Sound Regional Council, 2018). Data on 2,580 households and 5,019 individuals with 17,468 trips were collected via a one-to-four-day travel diary filled in by the participant via telephone or a web-based interface, conducted from Tuesday through Thursday; and data on 705 households and 1,235 individuals with 35,024 trips were collected via a new app-based seven-day travel diary, conducted from Monday through Sunday. The travel diary includes participant identification (person ID), identification of trip origin and trip destination at the scale of the census block group (trip ID), trip start/end time, and trip duration of each trip.
