This report provides a snapshot of the nature of work in 2019, with focus on the single most important trend
in work travel: the shift to nontraditional work. The goal is to help researchers and policymakers interested in
quantifying the amount and type of changes in the U.S. workforce in 2020 and later. This brief explores the
demographics and travel of workers in four types of non-traditional work: those who usually work at home, those
who telecommute, those who have flextime, and those involved in contract or "gig" work. Statistics with margins
of error are presented at the 90th confidence limit (±10 percent). 2021. 38 pp.
This report examines trends in vehicle availability in the U.S. from 2000 to 2017; presents overall trends, with
a focus on zero-vehicle households; and assesses the commute mode patterns of workers by their household
automobile availability. The analysis draws on three different data sources comprised of multiple associated
datasetsÑthe Public Use Microdata Samples of the U.S. Census and the American Community Survey, and the
National Household Travel Survey. 2021. 50 pp.
This brief explores the evolution of households as it relates to commuting. The household has been the basic
unit of analysis in trip generation and travel demand estimation since the beginning of regional modeling. This
brief provides a summary of how the composition and characteristics of households have changed over time,
and how those changes have contributed to changes in travel demand. This analysis focuses on the time period
since 1995, when the growth in travel rates started to slow. Since the turn of the millennium, travel rates in the U.S.
have declined. Population growth is fueling increases in road traffic, but not greater amounts of travel per person.

Transportation planners face considerable uncertainty regarding the development and deployment of emerging
transportation technologies. Nonetheless, the possible impacts of emerging technology on mobility and the
expected resulting changes in areas, including land use, environment, and economics, call for data and research
to support planning, policy, and operations at the city, regional, and state levels. To support that effort, this brief
provides a summary on emerging modes of travel, including ridehailing, ridesharing, micromobility, carsharing,
connected and autonomous vehicles, and telemobility. It also introduces the data available for analyzing each of
these modes, and provides suggestions for future datasets and methodologies to shed light onto their use.
