There has been a lively debate over using land use strategies to reduce automobile dependence over the past decade. As a part of the issue, this study investigates the spatial characteristics around workplaces and their relationships to commuting made by the employees in metropolitan Dallas-Fort Worth. The tools of geographic information systems (GIS) are utilized to measure workplace environs. Several statistical methods are applied to analyze commuting behavior. This study finds that low-density suburban workplaces are associated with shorter vehicle travel times but more drive-alone trips. While major suburban centers attain some level of compact development in terms of local activity mix and regional accessibility, employees in these centers are far more automobile dependent than employees in older centers in the central city. In the suburban locations, workplaces in residence-based centers and master planned communities with a mix of activities are associated with less drive-alone commuting and more carpooling. Workers take advantage of the abundance of activities, as larger and denser centers are associated with more non-work activity stops after work. Yet, the trip chaining is overwhelmingly driven by automobile use. This study also finds that spatial factors are significant in explaining commuting behavior. Yet, the importance of spatial factors varies with the aspect of travel. Spatial factors do a better job in explaining travel times than in explaining travel mode and trip chaining. The way a particular spatial factor affects commuting also varies with the aspect of travel. For instance, land use intensity factors are associated with longer travel times but less drive-alone trips. While this study suggests that concerted planning may affect travel, some socioeconomic variables, including income and automobile ownership, are strongly related to more automobile travel. The findings suggest that the land use strategies to cope with transportation and air quality problems, such as new urbanism and jobs-housing balance, would be a viable option in and around employment locations. But, such strategies should be carefully designed because of the differences in effectiveness of spatial factors with travel outcomes and the trade-offs between travel outcomes with a particular spatial factor.

Texas is changing dramatically; the most conservative population forecast indicates that Hispanics will account for 50% of the Texas population before 2035. Not only is the number of Hispanics on the rise in Texas, but also the foreign-born share has increased dramatically over the last 15 years. The State of Texas is now a majority minority state, and minority cohorts are expected to grow and become more than 65% of the Texas population before 2035. Transportation professionals in the State of Texas are wondering how these demographic changes will affect the transportation system. To gain an understanding of this, one must consider the prevalent travel behavior and attitudes of these minority groups, their cultural preferences, and their traveling mode preferences. This research provides an understanding of the travel behavior of Texas' burgeoning minority cohorts, and assists in identifying potential transportation policy concerns. For this analysis the National Household Travel Survey (NHTS) Add-On for the State of Texas is used, because it allows us to examine respondents by race/ethnicity and immigrant status. This study also helps determine how the travel behavior of minority cohorts may impact the state's transportation system in the near future, and possible implications to travel demand models are offered. In addition, this research attempts to foster further research on the travel behavior of burgeoning minority populations within the State of Texas. This study provides descriptive statistics, and multivariate models that examine the travel behavior of minority cohorts.

A specific objective of this scan of recent travel surveys is to facilitate the exchange of information among agencies and individuals having an interest in the design and conduct of household and other types of travel surveys. The information contained in this report complements the companion "Travel Survey Manual", published as part of the Travel Model Improvement Program (TMIP). The "Travel Survey Manual" is a reference document describing accepted practices and recent advancements for the most common types of travel surveys. Four purposes guided the development of this scan: to determine the general state-of-the-practice of travel surveys in this country; to identify the types of surveys being conducted, and the frequency of data collection; to compare United States survey practices to travel survey procedures being used in other countries; and, to assess the degree to which emerging state-of-the-art survey techniques are being introduced into practice.

This book brings together reports of original empirical studies which explore the impacts of the COVID-19 pandemic on urban mobility and transportation and the associated policy responses. Focusing on the California region, the book draws on this local experience to formulate general lessons for other regions and metropolitan areas. The book examines how the COVID-19 pandemic has had different impacts on vulnerable populations in cities. It explores the pandemic's impacts on the transportation industry, in particular public transit, but also on other industries and economic interests that rely on transportation, such as freight trucking, retail and food industries, and the gig-economy. It investigates the effect of the viral outbreak on automobile traffic and associated air quality and traffic safety, as well as on alternative forms of work, shopping, and travel which have developed to accommodate the conditions it has forced on society. With quantitative data supported with illustrations and graphs, transportation professionals, policymakers and students can use this book to learn about policies and strategies that may instigate positive change in urban transport in the post-pandemic period.

"Census microdata are the confidential records of specific individuals and housing units from whom Decennial Census or American Community Survey responses have been obtained. The U.S. Census Bureau also draws a sample from the full set of microdata and makes these sampled records available in the Public Use Microdata Sample (PUMS) data products, so that users can develop their own tabulations. These data are being used by state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) for studies, such as analyses of the commuting characteristics of population subgroups, and for supporting travel demand model and land use models."--Preface
