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

PSU Transportation Seminars

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 …

Pricing And Reliability Enhancements In The San Diego Activity-Based Travel Model, Joel Freedman

PSU Transportation Seminars

The estimation of demand for priced highway lanes is becoming increasingly important to agencies seeking to improve mobility and find alternative revenue sources for the provision of transportation infrastructure.

However, many modeling tools fall short of what is required for robust estimates of demand with respect to toll and managed lanes in two key areas:

• The value-of-time is often aggregate and not consistently defined throughout the model system, and
• The reliability of transport infrastructure is rarely taken into account.

This presentation describes an effort which implemented recommendations of the Strategic Highway Research Program C04 and L03\L04 tracks on pricing and …

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

PSU Transportation Seminars

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 and land use …

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

PSU Transportation Seminars

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.

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

TREC Webinar Series

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.

Congestion Modeling And Mitigation In The National Airspace System, David Lovell

PSU Transportation Seminars

Dr. Lovell will talk about three projects funded by NASA and the FAA, addressing congestion in the National Airspace System. Dr. Lovell's team developed diffusion-based queuing models of individual airports that could support better building blocks for network-wide congestion models. The advantage of the new models is their flexibility with respect to input distributions. In a study for the FAA, Dr. Lovell's team developed day-of-operations collaboration "languages" suitable for the FAA and individual carriers in order to collectively manage expected airspace disruptions. Finally, he will discuss a study on predictability in the airspace, with a focus on scheduled block times.

Next, the cell phone data was collected for the month of September 2013 for the following market segments: Average weekday resident HBW, HBO, NHB, and visitor NHB trips. The cell phone trips were …

Planning Transportation For Recreational Areas, Anne Dunning

PSU Transportation Seminars

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.

Understanding Where We Live And How We Travel, Kristina Marie Currans

PSU Transportation Seminars

Understanding changing residential preferences—especially as they are represented within land use and travel demand models—is fundamental to understanding the drivers of future housing, land use and transportation policies. As communities struggle to address a rising number of social challenges with increasing economic uncertainty, transportation and land use planning have become increasingly centered on assumptions concerning the market for residential environments and travel choices. In response, an added importance has been placed on the development of toolkits capable of providing a robust and flexible understanding of how differing assumptions contribute to a set of planning scenarios and impact future residential location …

Can Location Value Capture Pay For Transit? Organizational Challenges Of Transforming Theory Into Practice, Deborah Salon

PSU Transportation Seminars

Successful public transit systems increase the value of locations they serve. Capturing this location value to help fund transit is often sensible, but challenging.

This presentation will define location value capture, and synthesize lessons learned from six European and North American transit agencies that have experience with location value capture funding.

The opportunities for and barriers to implementing location value capture fall into three categories: (1) agency institutional authority, (2) agency organizational mission, and (3) public support for transit.

When any of these factors is incompatible with a location value capture strategy, implementation becomes difficult. In four of the cases …
