Recently, several studies found that suburban development is associated with the unbalanced choice of light duty trucks (LDTs). These studies have not shed much light, however, on the underlying direction of causality-whether neighborhood designs as opposed to attitudes towards vehicle choice more strongly influence individuals' decisions on vehicle type choice. The available evidence ...

The data is drawn from four survey instruments: an attitudinal survey, a travel diary, an attendance log, and an exit interview. The report provides an analysis and discussion of the travel impacts, telecommuter and manager attitudes, telecommuting retention, and telecommuting patterns associated with telecommuting center use.

The research analyzes data collected from an internet survey carried out in Northern California in 2006 (N= 967). The study adopts factor analysis to measure personal attitudes toward technology, traveling and shopping behavior, as well as channel-specific perceptions of store and internet. Seemingly- ...

In this project, the research team designed and implemented a wide-ranging travel survey that explores people\u2019s opinions about travel-related issues, together with how they use new mobility technologies and services, and travel in general. The study employed two sampling frames: (1) address-based stratified randomly sampled households, and (2) Georgia residents who participated in the 2017 National Household Travel Survey (NHTS) and agreed to be contacted for further surveys. The data were collected across about six months. The study explores five main themes: general travel behaviors, commute and work patterns, general opinions and attitudes, new and emerging technologies and services, and future transportation, with a specific focus on autonomous vehicles. Some findings include: despite the low levels of current ownership of alternative-fuel vehicles (2.2% of primary vehicles are hybrid/electric), respondents exhibit considerable interest in having such vehicles (59%); more than 5% \u201ccommute\u201d by working at home, compared to 3% who use transit; overall, ridehailing services seem to have more substitution effects than complementarity and generation effects, including both car-for-car substitution and net reductions in the use of active transportation and public transit modes; and half of respondents (51%) said they are likely or very likely to own a self-driving car, whereas 27% and 12% are likely or very likely to use a driverless taxi alone/with others and with strangers, respectively. Based on results, the study provides some policy implications.112

Research paper thumbnail of Heterogeneous residential preferences among Millennials and members of Generation X in California: A latent-class approach

Studies have theorized that a combination of temporary economic hardship, long-term societal changes, and changing preferences and attitudes have been responsible for Millennials’ unique residential choices. This study examines a less-explored question about the presence and significance of heterogeneity in residential preferences across and within generations. In doing so, this study employs a latent-class choice model on a commuter subsample of Millennials and members of Generation X (n=729) of the California Millennials Dataset, which collected a rich set of variables on various dimensions in Fall 2015. Using randomly-generated unlabeled choice sets at the US Census block group level, this study identifies three latent classes. The Younger, Pro-Urban Class (53% of our dataset; 66% of its millennial cases and 42% of its Gen Xers) behaves as the stereotypical Millennials in popular media, preferring urban amenities; the Affluent, Highly-Educated Class (32% of our dataset; 25% of its millennials and 38% of its Gen Xers) appears to pursue lifestyles and high socioeconomic status over homeownership or good school districts; and the Middle-Class Homeowner Class (15% of our dataset; 8% of its millennial cases and 21% of its Gen Xers) presents more traditional family-oriented suburban lifestyles. After the examination of shares of the three classes by age and neighborhood type, we provide suggestions for future research and effective planning responses.

Research paper thumbnail of Are Millennials More Multimodal? A Latent-Class Cluster Analysis with Attitudes and Preferences among Millennial and Generation X Commuters in California

Transportation, 2019

Two potential explanations for this phenomenon prevail in the literature. According to the first explanation, millennials often choose travel multimodality at least in part because of the effects of the economic crisis, which affected young adults more severely than their older counterparts. Another explanation points to the fact that millennials may have fundamentally different preferences from those of older birth cohorts. This paper presents an examination of millennials’ travel behavior as compared to the preceding Generation X, based on a survey of 1,069 California commuters. It shows that millennials adopt multimodality more often than Gen Xers, on average. However, the analysis also points to substantial heterogeneity among millennials and indicates that, perhaps contrary to expectations and the stereotype in the media, the majority of millennials are monomodal drivers in California. The paper contributes to the literature on millennials’ mobility in several ways. First, it rigorously classifies various forms of travel multimodality (on a monthly basis and distinctively taking trip purpose into account) through the analysis of a rich dataset that includes individual attitudes and preferences; second, it explores gradual changes of multimodality across age and generation; and third, it analyzes the effects of various demographic, built environment, and attitudinal attributes on the adoption of multimodality.
