  Citation × Citation Citation Abstract Copy Title: Factors Associated with the Bicycle Commute Use of Newcomers: Analysis of the 70 Largest U.S. Cities Author: Dann, Ryan Year: 2015 Bicycling is known to produce benefits for cities, in regards to reducing levels of congestion, generating positive health outcomes, and providing affordable transportation options to low-income families. Conventional analysis of urban bicycle commuting does not currently consider the importance of separating migrant, or “newcomer,” bicycle commute use from pre-existing resident bicycle commute use. The goal of this paper is to provide additional information on individual, social, and environmental factors that influence newcomer bicycle use for commuting purposes. This cross-sectional study used data from the 2007-2011 American Community Survey (5-year Estimates) to analyze the bicycle commute use of newcomers in the 70 largest U.S. cities. Relationships between newcomer bicycle commute use and socio-demographic, physical environment, and social environment factors were explored. Newcomer bicycle commute use has a strong positive association with pre-existing city-wide levels of bicycle commute use and a weak positive association with city-wide levels of bicycle infrastructure. After controlling for the built environment, cities with very high levels of pre-existing bicycle use are associated with a 690% higher likelihood of a newcomer’s bicycle commute use when compared to cities with low levels of pre-existing bicycle use. The results suggest that a newcomer’s bicycle use is related to demographics characteristics and pre-existing bicycle use, and that bicycle infrastructure has a relatively negligible influence. The findings may be useful for city planners and policymakers attempting to attract bicycle users to their cities.

  Citation × Citation Citation Abstract Copy Title: Analysis of Bus Collision Incidents Using Transit ITS and other Archived Operations Data Author: Strathman, James G., Wachana, Paul Herman, Callas, Steve Year: 2010 This report analyzes factors contributing to bus operations safety incidents at TriMet, the transit provider for the Portland Oregon metropolitan region. The analysis focuses on 4,631 collision and non-collision incidents that occurred between 2006 and 2009. Empirical analysis of these incidents draws on a wide array of operator-level data recovered by transit ITS technologies in combination with information from TriMet’s human resources, scheduling, and customer relations databases. Incident frequencies are estimated in relation to operators’ demographic characteristics, employment status, assigned work characteristics, service delivery and performance indicators, temporal factors, and customer information. Apart from identifying factors that are empirically related to the frequency of safety incidents, the findings offer insights into operations policies and practices that hold promise for improving safety.

Author: Ma, Liang, Dill, Jennifer Year: 2017 Do people perceive the built environment the same as we objectively measure it? If not, what are the relative roles of the objective versus the perceived environment on bicycling behavior? This study, based on data from Portland, Oregon, explored the match or mismatch between the objective and perceived bicycling environment and how it affects people’s bicycling behavior. The descriptive analysis indicated a fair agreement between perceived and objective measures. Older adults, women having children, less-educated and lower-income persons, and those who bicycle less tended to perceive their high-bikeable environment (measured objectively) as being a low-bikeable environment. In addition to the socio-demographics, this study also found that the social environment can play a role in the relationship between the objective and perceived environment. Finally, results of this study indicated that both the actual and perceived built environment are associated with bicycling behavior, particularly for utilitarian bicycling. For recreational bicycling, the objective environment attributes measured in this study are not significant factors, while perceptions do matter Title: Do People’s Perceptions of Neighborhood Bikeability Match “Reality”?

  Citation × Citation Citation Abstract Copy Title: The World Health Organization Age-Friendly Cities Project in Portland, Oregon, USA Author: Neal, Margaret B., DeLaTorre, Alan Kenneth Year: 2007 The older population is increasing in size in Portland, the state of Oregon, the United States, and the rest of the world. Our cities and regions are vital to the support of this demographic shift through the provision of quality built environments, services, and social, cultural, and civic engagement opportunities promote healthy and active aging. Over the next 30 years, the Portland-Vancouver metropolitan area will see dramatic growth in the proportion of the population that is aged 65 and older. Although the total population will increase by 47 percent, the 65+ population will more than double, growing by over 137 percent, to comprise 17 percent of the population in 2030, compared to 10.5 percent in 2000. Fueling this increase will be the aging of the baby boomers. As a city and a region, changes that will enhance the quality of life, independence, and well-being of our aging population can be made. These include addressing important needs that are identified, and taking advantage of assets and resources that an older and experienced population provides.

  Citation × Citation Citation Abstract Copy Title: The Theory of Travel Decision-Making: A Conceptual Framework of Active Travel Behavior Author: Singleton, Patrick Allen Year: 2015 We present a unifying conceptual framework of active travel behavior called the theory of travel decision-making. It integrates seminal travel-related concepts from economics, geography, and psychology with active travel behavior theories and empirical research. The framework abstracts an individual’s thought process around short-term travel decisions and explains the roles of activities, built environment factors, socio-demographics, attitudes and perceptions, and habit. Our primary objective is to inform travel behavior research by meeting the need for a theoretical framework capable of guiding studies on active transportation. The framework could also support active transportation planning and analysis methods by informing the development of travel forecasting tools that better represent the unique influences on walking and bicycling. This presentation summarizes the theoretical foundations of active travel behavior; presents and describes the conceptual framework and its components in detail; notes research needs; and assesses the contributions of the framework to active travel behavior theory, research, and practice.

  Citation × Citation Citation Abstract Copy Title: Examining Consumer Behavior and Travel Choices Author: Clifton, Kelly J., Muhs, Christopher Devlin, Morrissey, Sara, Morrissey, Tomás, Currans, Kristina Marie, Ritter, Chloe Year: 2013 This study represents a first attempt to answer a few of the questions that have arisen concerning multimodal transportation investments and the impacts of mode shifts on the business community. This research aims to merge the long history of scholarly work that examines the impacts of the built environment on non-work travel with the relatively new interest in consumer spending by mode of travel. This empirical study of travel choices and consumer spending across 89 businesses in the Portland metropolitan area shows there are important differences between the amounts customers spend on average at various businesses by their mode of travel. However, these differences become less pronounced when we control for demographics of the customer and other attributes of the trip. This study of consumer spending and travel choices has some compelling findings that suggest some key spending and frequency differences by mode of travel that will likely invigorate the discussion of the economic impacts of these modes. Key findings are: 1) Bicyclists, pedestrians and transit riders are competitive consumers: When demographics and socioeconomics are controlled for, mode choice does not have a statistically significant impact on consumer spending at convenience stores, drinking establishments and restaurants. When trip frequency is accounted for, the average monthly expenditures by customer modes of travel reveal that bicyclists, transit users and pedestrians are competitive consumers and, for all businesses except supermarkets, spend more on average than those who drive and 2) The built environment matters: We support previous literature and find that residential and employment density, the proximity to rail transit, and the amount of automobile and bicycle parking are all important in explaining the use of non-automobile modes. In particular, provision of bike parking and bike corrals are significant predictors of bike mode share at the establishment level. Other findings lend more insight into the relationship between consumer behavior and travel choices. For the non-work destinations studied, the automobile remains the dominant mode of travel. Patrons are largely arriving by private vehicle to most of the destinations in this study, particularly to grocery stores where larger quantities of goods tend to be purchased. But, high non-automobile mode shares and short travel distances exist in areas of concentrated urban activity. In sum, this study provides some empirical evidence to answer the questions of business owners about how mode shifts might impact their market shares and revenues. More work is needed to better understand the implications of future changes and to provide a robust assessment of the returns on these investments and their economic impacts.
