Peak Pedaling: Has Portland Bicycling Reached The Top Of The Logistic Curve?, Robert McCullough 2016 McCullough Research

Peak Pedaling: Has Portland Bicycling Reached The Top Of The Logistic Curve?, Robert Mccullough

TREC Friday Seminar Series

The recent City Club report on bicycling provided an opportunity to collect and analyze a number of data sets including the new Hawthorne Bridge data. One question is where Portland bicycling on the logistic curve -- a common tool for judging the maturity of a developing product or activity. Logistic curves are used for marketing, for epidemiology, and even for visits to Indian owned casinos. The preliminary evidence is that we are reaching the horizontal area of the curve. Additional evidence Our further research into future policies indicates a shift to bicycle boulevards in order to attract more risk averse riders.


Can You Get A Ticket? Adaptive Railway Booking Strategies By Customer Value, Jiana-Fu Wang, Ren-Huei Huang 2016 National Chung Hsing University

Can You Get A Ticket? Adaptive Railway Booking Strategies By Customer Value, Jiana-Fu Wang, Ren-Huei Huang

Journal of Public Transportation

This paper integrates a customer segmentation method with a discrete event simulation model to bridge the gap between identifying customer behaviors and using this knowledge to respond to customers and make the best use of resources. Three strategies are proposed and examined to improve the operation efficiency of a ticket-booking system. Their objective is to assist high-value customers in obtaining the tickets they want and/or reduce cancellations and failure-to-pays from low-value customers. Our simulation results demonstrate that the high-value, customer-friendly strategy beats all in assisting high-value customers and simultaneously improves railway operation performance. Additionally, the indirect, low-value customer abandonment ...


How Intermediate Capacity Modes Provide Accessibility And Resilience In Metropolitan Transit Networks: Insights From A Global Study Of 19 Cities, Jan Scheurer 2016 RMIT University

How Intermediate Capacity Modes Provide Accessibility And Resilience In Metropolitan Transit Networks: Insights From A Global Study Of 19 Cities, Jan Scheurer

Journal of Public Transportation

Drawing on the Spatial Network Analysis of Multimodal Urban Transport Systems (SNAMUTS) accessibility tool, this paper introduces comparative results of public transport network performance measures in 19 metropolitan regions in developed countries. These results are assessed typologically and functionally to highlight the contribution of each common public transport mode to maximize (or not) the integration of transport networks with the urban structure to optimize accessibility outcomes. It is shown that the capacity and performance spectrum embodied by each mode represents a gradual scale that allocates a specific niche to intermediate modes, particularly trams that are present in half the cities ...


Public Transit Equity Analysis At Metropolitan And Local Scales: A Focus On Nine Large Cities In The Us, Greg P. Griffin, Ipek N. Sener 2016 Texas A&M Transportation Institute

Public Transit Equity Analysis At Metropolitan And Local Scales: A Focus On Nine Large Cities In The Us, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Recent studies on transit service through an equity lens have captured broad trends from the literature and national-level data or analyzed disaggregate data at the local level. This study integrates these methods by employing a geostatistical analysis of new transit access and income data compilations from the Environmental Protection Agency. By using a national data set, this study demonstrates a method for income-based transit equity analysis and provides results spanning nine large auto-oriented cities in the US. Results demonstrate variability among cities’ transit services to low-income populations, with differing results when viewed at the regional and local levels. Regional-level analysis ...


A General Framework For Price Regulation Of Airports, Sock Yong PHANG 2016 Singapore Management University

A General Framework For Price Regulation Of Airports, Sock Yong Phang

PHANG Sock Yong

Price cap regulation (PCR) was first implemented for privatized utilities in the UK in the 1980s. It has since been adopted by numerous countries as a regulatory regime in several sectors. This paper focuses on the development of different forms of price regulation of airports of which PCR is one variant. In countries where airport privatization is still in the early stages, the spectrum of airports and varied nature of regulatory regimes can be confusing and the lack of a general framework can itself become an obstacle to privatization. This paper proposes a general framework comprising decisions to be made ...


Determinants Of Mobility Resource Ownership In Switzerland: Changes Between 2000 And 2010, Nicole Andréa Mathys, Matthias Kowald, Barbara Kieser, Andreas Justen 2016 Federal office for Spatial Development, University of Neuchâtel

Determinants Of Mobility Resource Ownership In Switzerland: Changes Between 2000 And 2010, Nicole Andréa Mathys, Matthias Kowald, Barbara Kieser, Andreas Justen

Nicole Andréa Mathys

The future development in mobility resource ownership is of great interest as the individual mobility behavior has critical impacts on transport infrastructure, land use, energy consumption, and environmental issues, such as greenhouse gas emissions and local air pollutants. Analysis and forecasts of mobility resource ownership as needed for example in transport modelling or forecast studies, however, usually employ data of the latest national travel surveys available. Therefore, changes in mobility resource ownership over time are often ignored. Estimating logit-based decision models on the large scale Swiss national travel survey data for 2000 and 2010, the study identifies determinants of mobility ...


Realistic Or Utopian? Coordinating Transit And Land Use To Achieve Equitable Transit-Oriented Development, Ian Carlton 2016 EcoNorthwest

Realistic Or Utopian? Coordinating Transit And Land Use To Achieve Equitable Transit-Oriented Development, Ian Carlton

TREC Friday Seminar Series

Equitable transit-oriented development (E-TOD)—the prioritization of social equity as an outcome of TOD implementation—has become a U.S. DOT policy stance, an objective of many other government bodies, and part of many NGOs' missions. But is it feasible to coordinate transit and land use in ways that allow us to achieve these goals, or is this a classic example of a wicked problem?

This talk will use Portland as a case study to explore some of the internal contradictions inherent in E-TOD goals, the systemic challenges that must be considered, and glimmers of hope for delivering E-TOD. Transportation ...


Spaceways: Airspace In Outer Space, Scott Haeffelin 2016 Embry-Riddle Aeronautical University

Spaceways: Airspace In Outer Space, Scott Haeffelin

Space Traffic Management Conference

Forecasted future demand in space travel is driving the need for the development of space traffic management. Currently, orbital space traffic is mostly unregulated with internationally agreed upon best practices and self-interest driving space operators to avoid collisions with other spacecraft. This paper explores the future of space travel by presenting a concept of creating “airspace in space” or spaceways to manage the ever growing volumes of space traffic. Spaceways are analogous to airspace for aircraft with the goal of increasing levels of safety and reducing probabilities of collision. These goals can be achieved by creating traffic rules, defining valuable ...

What are the job, residential development and market rent outcomes of Light Rail Transit (LRT), Streetcar Transit (SCT) and Bus Rapid Transit (BRT)?

LRT, SCR and BRT investments are spreading rapidly across the country but there is scant evidence of their effect on where people work and live, and effects on market rents as an indicator of value. This webinar will summarize several years of NITC-sponsored research into development outcomes associated with these transit investments. The webinar will be led by NITC researcher Arthur C. Nelson who was the principal investigator of two projects: Do TODs Make a Difference? and ...


Lessons From The Development Of A Guidebook On Pedestrian And Bicycle Connections To Transit, Nathan McNeil, Allison Boyce Duncan, Drew DeVitis 2016 Portland State University

Lessons From The Development Of A Guidebook On Pedestrian And Bicycle Connections To Transit, Nathan Mcneil, Allison Boyce Duncan, Drew Devitis

TREC Friday Seminar Series

To improve safety and increase transit use, transit agencies and the jurisdictions they serve have to approach transit service as door-to-door not just stop-to-stop.

Walking and bicycling are key modes for transit access.

Working with the Federal Transit Administration, a team from Portland State University developed a guidebook on improving pedestrian and bicycle access to transit (forthcoming). As part of the guidebook process, the PSU team conducted case studies on best practices of recent efforts in Minneapolis, Los Angeles and Atlanta.

This presentation will cover key lessons from the case studies, along with an overview of the guidebook.


Individual Control Of Risk: Seat Belt Use, Subjective Norms And The Theory Of Reasoned Action, Juanita V. Field, Kenneth D. Boehm, Kevin M. Vincent, Jessica L. Sullivan 2016 University of New Hampshire

Individual Control Of Risk: Seat Belt Use, Subjective Norms And The Theory Of Reasoned Action, Juanita V. Field, Kenneth D. Boehm, Kevin M. Vincent, Jessica L. Sullivan

RISK: Health, Safety & Environment

When faced with a risk for which an inexpensive solution is available, individuals often choose the risk rather than the solution. Protection from certain kinds of risks, e.g., using seat belts or condoms or insulating against radon, is largely under personal control, but individuals often choose not to comply with behaviors which would reduce the risk. The Theory of Reasoned Action (TRA) has been used to predict when individuals will comply. The authors attempted to validate aspects of the TRA by the use of scenarios. Factor analysis of their data supports the theory that intention is a major determinate ...


Webinar: Transit Signal Priority Evaluation And Performance Measures, Miguel Figliozzi 2016 Portland State University

Webinar: Transit Signal Priority Evaluation And Performance Measures, Miguel Figliozzi

Miguel A. Figliozzi

Transit signal priority (TSP) can reduce transit delay at signalized intersections by making phasing adjustments. TSP is a relatively inexpensive tool to provide faster and more reliable transit service. This webinar addresses TSP real-word performance measures as well as data integration and evaluation challenges. Results of the TSP evaluation in an arterial corridor in Portland, Oregon indicate that a timely and effective TSP system requires a high degree of sophistication, monitoring, and maintenance. TSP timing is crucial to reduce transit delay.

Key takeaways include: performance measures, methodology, analysis of early green and red extension pros and cons, novel real-world results.

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

Miguel A. Figliozzi

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.

Planning Transportation For Recreational Areas, Anne Dunning 2016 University of Kansas

Planning Transportation For Recreational Areas, Anne Dunning

TREC Friday Seminar Series

Population growth and increased accessibility of formerly remote destinations have created new needs for planning mobility to and within recreational areas.

Transportation planners studying recreational travel face unusual travel-demand peaks, travelers who are often unfamiliar with their surroundings, and a uniquely important need for traveler and community communication. Planners must consider what characteristics of an individual area make it attractive to visitors, as well as local goals for the special resources of the area.

This presentation will characterize unique facets of mobility in recreational areas, and pose approaches to planning transportation systems to serve them.
