Crowdsourcing Cycling Safety And Route Data With The “Orcycle” Smartphone App, Miguel Figliozzi
Crowdsourcing Cycling Safety And Route Data With The “Orcycle” Smartphone App, Miguel Figliozzi
PSU Transportation Seminars
ORcycle is a new smartphone application (for both Android and iOS) developed by Transportation, Technology, and People (TTP) lab researchers at Portland State University as part of an Oregon Department of Transportation (ODOT) research project. ORcycle collects user, route, infrastructure, crash, and safety data. ORcycle was successfully launched in early November 2014 and presents many improvements over existing or similar apps. Initial data findings and insights will be presented. Lessons learned as well as opportunities and challenges associated with smartphone data collection methods will be discussed. More information about the app can be found here: http://www.pdx.edu/transportation-lab/orcycle.
Transportation System Impacts On Bicyclists' Air Pollution Risks: Considerations For System Design And Use, Alexander Y. Bigazzi, Miguel Figliozzi, James F. Pankow, Wentai Luo
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.
Factors Associated With The Bicycle Commute Use Of Newcomers: Analysis Of The 70 Largest U.S. Cities, Ryan Dann
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 …
The Theory Of Travel Decision-Making: A Conceptual Framework Of Active Travel Behavior, Patrick Allen Singleton
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 …

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
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
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
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 …
