Transportation System Impacts On Bicyclists' Air Pollution Risks: Considerations For System Design And Use, Alexander Y. Bigazzi, Miguel Figliozzi, James F. Pankow, Wentai Luo

PSU Transportation Seminars

Health risks associated with air pollution uptake while bicycling are often cited as a potential drawback to increased bicycling in cities. This seminar will provide an overview of how roadway and travel characteristics impact bicyclists' uptake of traffic-related air pollution. Specific considerations for planners and designers of urban transportation systems to mitigate risks for travelers will be discussed. In addition, the extent to which bicyclists themselves can unilaterally reduce their pollution uptake will be described. This seminar synthesizes findings from a recently completed doctoral dissertation at Portland State University and from the broader literature.

The Purpose, Function, And Performance Of Streetcar Transit In The Modern U.S. City: A Multiple-Case-Study Investigation, Mti Report 12-39, Jeffrey Brown, Hilary Nixon, Luis Enrique Ramos

Mineta Transportation Institute

The streetcar has made a remarkable resurgence in the United States in recent years. However, despite the proliferation of streetcar projects, there is remarkably little work on the streetcar’s role as a transportation service. This study examines the experiences of the modern-era streetcars operated in Little Rock, Memphis, Portland, Seattle, and Tampa. The authors discovered that in these cities, the primary purpose of the streetcar was to serve as a development tool (all cities), a second objective was to serve as a tourism-promoting amenity (Little Rock, Tampa), and transportation objectives were largely afterthoughts with the notable exception of Portland, and …

The Theory Of Travel Decision-Making: A Conceptual Framework Of Active Travel Behavior, Patrick Allen Singleton

PSU Transportation Seminars

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 …

Factors Associated With The Bicycle Commute Use Of Newcomers: Analysis Of The 70 Largest U.S. Cities, Ryan Dann

PSU Transportation Seminars

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 …

Webinar: Exploring Pedestrian Responsive Traffic Signal Timing Strategies In Urban Areas, Sirisha Murthy Kothuri

TREC Webinar Series

The role of walking in the development of healthy, livable communities is being increasingly recognized. In urban areas, intersections are often viewed as a deterrent to walking, as their operation primarily favors automobiles, leading to large and unnecessary delays for pedestrians. There is currently very limited research on accommodating and/or prioritizing pedestrians at signalized intersections in the North American context. Pedestrians are often considered as a deterrent to efficient vehicular traffic flow and therefore active efforts to include them in operational decisions at intersections have been lagging. This research aims to fill that gap by understanding factors that influence pedestrian …

Who Uses Peer-To-Peer Carsharing? Early Exploration, Anaïs Mathez

PSU Transportation Seminars

Peer-to-peer (P2P) carsharing is a system where a facilitating company connects car owners to car renters. Such systems are relatively new in the U.S. This paper aims to understand who is participating in P2P carsharing as a renter (as opposed to as an owner), why they join, whether and how often they rent vehicles, and why. Exploring these questions may provide insight on the potential for P2P carsharing to meet public policy objectives of reducing the impacts of personal vehicle ownership and use and providing mobility options for underserved populations. The analysis is based on 465 study participants who enrolled …

Leveraging Signal Infrastructure For Non-Motorized Counts In A Statewide Program: A Pilot Study, Bryan Philip Blanc

PSU Transportation Seminars

Transportation agencies are beginning to explore and develop non-motorized counting programs. This paper presents the results of a pilot study testing the use of existing signal infrastructure – 2070 signal controllers with advanced software to log pedestrian phase actuations and detections from bicycle lane inductive loops – to count pedestrians and bicycles. The pilot study was conducted at a typical suburban signalized intersection with heavy motorized traffic that was instrumented on all four approaches with pedestrian push buttons and advance inductive loops in the bicycle lane for signal operation. One day (24 hours) of video data were collected as ground …

Influential Vectors In Fuel Consumption By An Urban Bus Operator, João De Abreu E Silva

PSU Transportation Seminars

In an era of reduced government funding, transit operators struggle to reduce operating costs and increase revenues. Energy costs account for an important share of the total costs of urban and suburban bus operators. Using a case study of one operator in Lisbon, Portugal, this talk will expand upon the empirical research on bus transit operation costs and identify the key factors that influence the energy efficiency of the overall bus fleet. Our results of a multivariate analysis find the following dimensions influence transit energy efficiency: vehicle type, commercial speed, road grades and bus routes; and to a lesser extent …

Impact Of Freight Traffic On School Walking Decisions In Urban Environments, Stephanie S. Ivey, Marian Levy, Marla B. Royne, Kelsey Ford, Kranthi Guthikonda

Journal of Transportation Management

In light of the decline in social acceptance of walking and biking to school, there is a critical need to examine issues impacting school transportation decisions and to identify strategies to promote healthier behavior. In urban areas with high volume freight corridors, factors affecting school walking decisions can be complicated by increased truck and rail traffic. This paper presents findings from a study of urban neighborhoods in a major southeastern city, including those that are adjacent to freight corridors. Perceptions of neighborhood residents are compared in the context of existing infrastructure and network characteristics (urban vs. urban freight-centric). The results …

The Political Correlates Of Sustainable Development: A Case Study Of Winter Park, Fl, Ariella Lvov

Honors Program Theses

How do cities find the path to sustainable development policy when confronted with constituent opposition? To address this dilemma, a case study of a small, land-locked city in Central Florida was conducted, whose long battle with sustainable development has been, at times, both successful and unsuccessful. Winter Park provides an excellent backdrop for studying which political correlates are requisite for the successful execution of growth policy. This study explores three sustainable development initiatives in Winter Park: (a) light rail, (b) SunRail, and (c) transit-oriented development. The researcher conducted an analysis of both archival research and structured interviews with local elected …

Transit And Economic Resilience, Arthur C. Nelson, Matt Miller, Joanna P. Ganning, Philip Stoker, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Do fixed-guideway transit systems facilitate resilience with metropolitan areas? There is little literature making this connection theoretically and none testing it empirically. This paper helps close this gap in both respects. In evaluating metropolitan areas with light rail transit systems the authors find evidence that transit corridors on the whole performed better than control corridors during the recovery period of two recessions: that of the early 2000s and the so-called Great Recession. In particular, during the Great Recession transit corridors outperformed control corridors among many economic sectors. Outcomes were more impressive during recoveries from both the recession of the early …
