This paper uses data from the 1995 Nationwide Personal Transportation Survey and the 2001 National Household Travel Survey to examine trip-chaining trends in the United States. The research focuses on trip chaining related to the work trip and contrasts travel characteristics of workers who trip chain with those who do not, including their distance...

The proportion and number of older workers (those older than 65) are expected to increase significantly in the coming decades, and examining this cohort's travel behavior may provide insight into this potential boom. This study is an exploratory analysis to describe working patterns of the older population today, to examine their work trips, and to...

Mode share', or the proportion of trips by how people travel, is often used in trends analysis to track the changes in travel by private auto, transit, and walking, for example. However, analysts and planners should exercise caution when using 'mode share' to compare different time periods. The 'share' of trips by any one category of travel can be...

This brief examines the difference between how commuters 'usually' traveled to work last week and how they report commuting on an individual (randomly assigned) workday.

This brief examines the longer trips in the National Household Travel Survey by mode of travel and purpose.

The 2017 National Household Travel Survey results indicate that overall people are traveling less than previously. Researchers and policymakers wonder what effect large-scale demographic changes have on travel demand. The Baby Boomers are starting to move into the empty-nest and retirement stages of their lives, typified by lower overall travel rat...

Short article/brief describing the demographics and travel characteristics of multi-generational households. The findings show that caretakers of elderly parents are more likely women who offer critical transport--especially to medical services-- as part of their care-taking responsibilities.

Two different approaches are used to collect trip generation data that form the basis of both site analysis--for example, ITE trip generation rates--and longer term forecasting--for example, future land-use productions and attractions. This paper tries to clearly describe the theory and assess the strengths and weaknesses of each approach. In addit...

The United States is in a significant period of change. The significant growth in travel that the US has experienced since the 1960's is a product of demographic and economic changes including increases in vehicle ownership, baby boomers and women entering the workforce, and dramatic growth in personal income. More recently however, data are painti...

Introduction This paper is part of a series of briefing papers to be prepared for the National Surface Transportation Policy and Revenue Study Commission authorized in Section 1909 of SAFETEA-LU. The papers are intended to synthesize the state-of-the-practice consensus on the issues that are relevant to the Commission's charge outlined in Section 1...

The National Personal Travel survey has been conducted periodically by the U.S. Department of Transportation since 1969. In this feature, trends and data from the most recent survey in 2001 and the entire data series are used to highlight important patterns of travel and vehicle use in American households.

This paper presents the results of an effort funded by the FHWA Office of Policy to conduct analyses for creating tour-based files for the 1995 Nationwide Personal Transportation Survey (NPTS) and the 2001 National Household Travel Survey (NHTS). This research examines the effect of different rules of inclusion for person-trips within chains and ad...

Research suggests that households with interrupted telephone service can be used as a proxy for households with no telephone service to help mitigate the inherent frame bias in a random digit-dialing (RDD) sample. If a sufficient quantity of households with a history of interrupted service can be surveyed, some researchers suggest that probability...

The primary objective of the intermodal rail-yard truck survey was to gain a better type of trucks, the number of trips and the characteristics of trips made to intermodal yards on bn average weekday.

An increasing amount of travel, both long- and short-distance trips, is made in private vehicles for recreation. Peak congestion around attractions and leisure spots can be worse than congestion in the city center during peak periods. Moreover, recreational travel within, to, and through metropolitan areas contributes to congestion problems and poi...

Gender and household life-cycle together affect daily travel behavior. While this makes intuitive sense, transportation planners and policy makers/shapers have done little to understand what effect and impact these factors have on daily transportation choices. This paper uses the 1995 Nationwide Personal Transportation Survey (NPTS) to examine trip...
