Model-Based Analytics And Processes For Transportation Investment Alternatives Analyses: From Least Cost Planning To Multi Criterion Evaluation, Jeff Frkonja

PSU Transportation Seminars

Many public and private organizations that make decisions regarding whether and how to invest in transportation assets or programs do so via a structured decision-support process. This talk will address the technical aspects of the family of such processes that use travel demand model outputs—and other sources of quantified performance data—as inputs to analytic tools including benefit cost analysis (BCA) and multi criterion evaluation. Example applications of this framework have included tolling and pricing studies, capital investment alternatives analyses, and programmatic evaluations. Example processes include "Least Cost Planning" frameworks borrowed originally from the power generation industry.

The talk will also …

Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub

PSU Transportation Seminars

Securing and expanding the broad right to bicycle, including the right to adequate and safe street space and related infrastructure for cycling along with other policies and protections for cyclists, is the obvious goal of cycling advocacy efforts in their various forms. All rights are situated within frameworks for promulgating and insuring they are honored, and the right to cycling is no different. This project investigates how the right to bicycle falls within various rights frameworks, focusing on broad human rights and civil rights frameworks while reflecting as well on traffic safety codes and transportation planning frameworks. While certain aspects …

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …

The Trade-Offs Between Population Density And Households' Transportation-Housing Costs, Haizhong Wang

PSU Transportation Seminars

As metropolitan area governments and others promote density-promoting “smart growth” policies, finer analysis is needed to quantify the impact of such policies on households' transportation and housing costs. Existing research suggests that households in urban areas trade-off between housing costs and transportation costs, but does not explore how policies to increase urban densities might explicitly impact this balance. Furthermore, the research does not adequately distinguish between the effect of urban area density and the effects of other factors associated with urban area density (e.g metropolitan area size and household incomes) on housing costs. This research uses the 2000 Census Public …

The Backstory: How Livablestreets Advocates Changed Boston, Jeffrey Rosenblum

PSU Transportation Seminars

Local grassroots advocacy organizations play a critical role in shaping the future of cities but receive very little attention in research, especially insofar as understanding the most effective tactics that should be used by these organizations to achieve their objectives. When LivableStreets Alliance was founded in 2005, The City of Boston had 3/8 of one mile of bicycle lanes. Over the past decade, we have seen a sea change. Boston has published a nationally-recognized Complete Streets Guide, MassDOT has incorporated cycle-track designs into several federally-funded projects, and highway overpasses are slated for removal. What is LivableStreets’ role in shifting policy, …

Affordable Housing As A Prerequisite For A Safe, Healthy, Equitable Transportation System: Evidence From A Nationwide Evaluation Of Location Efficiency Within The Low-Income Housing Tax Credit (Lihtc) Program, Arlie Steven Adkins

PSU Transportation Seminars

Mountains of research over the last several decades show that how we get around and how much physical activity we get are closely linked with the built environment of the neighborhoods where we live. This means that the health, economic, and environmental benefits associated with active travel and transit are place-based and that affordable housing in walkable, location efficient places needs to be thought of as a critical component of planners’ efforts to provide safe, healthy, and equitable transportation systems. This talk will provide an overview of the links between affordable housing and transportation planning and present research findings from …

Evaluation Of A Shared Space Alternative In Morgantown, Wv, Avinash Unnikrishnan

PSU Transportation Seminars

Pedestrian and vehicle movement conflicts and the associated safety and efficiency issues have always been addressed in traffic engineering based on the principle of separation through bridges, tunnels, or signals. Pioneered by Hans Monderman, shared space is a new approach in transportation design which inverts this paradigm of separation and designs streets with no demarcations or access restrictions. Shared space has been implemented in a number of cases in Europe with improved efficiency and safety. This research focuses on a specific case study for analyzing the possible implementation of shared space in the United States on the West Virginia University …

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing …

Crowdsourcing The Collection Of Transportation Behavior Data, Christopher Bone, Seth Kenbeek, Ken Kato, Jacob Bartruff

TREC Final Reports

Understanding the travel behaviors of individuals who use public transit is essential for enhancing the performance, sustainability and efficiency of public transportation. Contemporary methods for collecting data on transportation behavior are focused on manual or automated procedures for counting the number of individual passengers entering or exiting transit vehicles. While such methods provide useful data for understanding transit demand throughout a network, they ignore the important details of how passengers travel to and within a network as well as their personal experiences during their commute, all of which can enrich the ability of transit agencies to provide sustainable transportation. To …

Webinar, Part I: Americans' Views Of Transportation And Livable Communities, Jennifer Dill, Hugh Morris

TREC Webinar Series

The National Association of Realtors® and Portland State University conducted a nationwide survey in the 50 largest metropolitan areas, asking Americans about where they live, where they want to live, and their travel habits.

This webinar will present the key findings from that survey, including people’s preferences to live in mixed-use, walkable communities and what may help them walk, bicycle, and take transit more. The large sample (3,000) allows us to look at demographic differences, including between the generations (Millennials, Baby Boomers, etc.).

Development Of A Pedestrian Demand Estimation Tool: A Destination Choice Model, Christopher D. Muhs

PSU Transportation Seminars

There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Planners, engineers, and others seek improved tools to estimate pedestrian demand that are sensitive to environmental and demographic factors at the appropriate scale in order to aid policy-relevant issues like air quality, public health, and smart allocation of infrastructure and other resources. Further, in the travel demand forecasting realm, tools of this kind are difficult to implement due to the use of spatial scales of analysis that are oriented towards motorized modes, vast data requirements, and computer processing limitations.

Travel Decisions & Their Implications For Urban Transportation: From Campus Transportation To Statewide Modeling, Gulsah Akar

PSU Transportation Seminars

The ability to forecast future transportation patterns under a particular land-use scenario or urban form is key to making informed decisions at the local and regional levels.

Although several researchers have explored the links between the built environment, socio-demographics and travel behavior, a consensus is not reached.

This talk highlights two recent projects. The first project focuses on individuals’ attitudes towards transportation, neighborhood characteristics and their effects on campus commuters’ transit use, and addresses the question whether attitudes, the built environment or a combination of both explains the resulting transit use better.

The second part presents the Regional Land Use …

2014 Transit Oriented Developments Survey, Jennifer Dill, Nathan Mcneil

TREC Final Reports

This report presents results from surveys of residents at several transit-oriented developments (TODs) in Portland, Hillsboro, Tigard, and unincorporated Clackamas County. The research complements our previous survey work for Metro done at eight TODs in 2010 and 11 TODs in 2007.

Using Multimodal Performance Measures To Prioritize Improvements On Us 101 In San Luis Obispo County, Jessica Berry

PSU Transportation Seminars

The US 101 Corridor Mobility Master Plan in San Luis Obispo was a two-year planning effort that evaluated the 70 mile corridor on 12 performance measures. This collaborative effort was led by the San Luis Obispo Council of Governments (SLOCOG).

Performance based planning is becoming more important for agencies receiving State and Federal funding. Smaller, rural regional agencies will have to find ways to collect, report, and use performance metrics with limited resources. SLOCOG's first performance-based planning effort was the US 101 Corridor Mobility Master Plan, funded through a State grant.

Funding for this project came from a …

Dash: The Portland Region's Next-Generation Activity-Based Model, Richard Walker

PSU Transportation Seminars

DASH is the next generation activity based model being developed by the Metro Research Center. Upon completion, it will be one of the most advanced in the nation. This model will be used extensively in estimating the activity and travel response of individuals to policies and infrastructure investments. Compared to past models, it will include enhanced consideration of the socio-economic roles of individuals, discrete temporal dynamics, and intra-household dependencies.

Geometric Design, Speed, And Safety, Richard J. Porter

PSU Transportation Seminars

In this seminar, Dr. Porter will explore the interactions of geometric design decisions, speed, and safety. A performance-based approach to this topic will be considered given the availability of several key documents, including the Highway Safety Manual and TRB's Modeling Operating Speed: Synthesis Report as well as a significant body of published research. A historical look at the design speed concept will show that while the design speed definition has changed on more than one occasion, the same basic but flawed philosophy that relates design speed to a “safe speed” is still reflected in supplemental guidance related to design speed …

The Sfpark Pilot: Using Data To Make Cities Better, Kathryn Doherty-Chapman

PSU Transportation Seminars

SFpark was a federally-funded pilot program of a new approach to managing parking in San Francisco. It utilized real time data to identify parking availability, and demand-responsive parking pricing to help make parking easier to find. Parking management is an invaluable transportation demand management tool and the SFpark pilot demonstrated how data can help cities make smarter decisions. Come hear about the pilot evaluation results from a former SFpark staffer and PSU alum.

Transit-Oriented Development And Equity In Latino Neighborhoods: A Comparative Case Study Of Macarthur Park (Los Angeles) And Fruitvale (Oakland), Gerardo Francisco Sandoval, Roanel Herrera

TREC Final Reports

Transit-oriented development (TOD) projects in low-income neighborhoods have the potential to provide needed transportation access to a segment of the population that stands to benefit significantly from these large-scale transit infrastructure projects. This research project reveals that large-scale TOD projects have the potential of leading to neighborhood revitalization and equitable outcomes in low-income Latino communities. But these positive outcomes depend on both the process and context of these particular neighborhoods, and how transportation planners incorporate the various forms of political, financial and cultural capital that exist in these communities into the planning and implementation process of TOD projects. This comparative …

Webinar: A Comprehensive Evaluation Of Protected Cycling Facilities: Lessons From Five Cities, Christopher Monsere

TREC Webinar Series

As cities move to increase levels of bicycling for transportation, many practitioners and advocates have promoted the use of protected bike lanes (also known as “cycle tracks” or “protected bikeways”) as an important component in providing high-quality urban infrastructure for cyclists. These on-street lanes provide more space and physical separation between the bike lane and motor vehicle lane compared with traditional striped bike lanes. However, few U.S. cities have direct experiences with their design and operations, in part because of the limited design guidance provided in the past. There is limited research from North America on protected bike lanes, but …

Self-Organizing Signals: A Better Framework For Transit Signal Priority, Peter G. Furth

PSU Transportation Seminars

Actuated traffic signal control logic has many advantages because of its responsiveness to traffic demands, short cycles, effective use of capacity leading to and recovering from oversaturation, and amenability to aggressive transit priority. Its main drawback has been its inability to provide good progression along arterials. However, the traditional way of providing progression along arterials, coordinated-actuated control with a common, fixed cycle length, has many drawbacks stemming from its long cycle lengths, inflexibility in recovering from priority interruptions, and ineffective use of capacity during periods of oversaturation. This research explores a new paradigm for traffic signal control, “self-organizing signals,” based …

Empirical Evaluation Of Transit Signal Priority Through Fusion Of Heterogeneous Transit And Traffic Signal Data And Novel Performance Measures, Wei Feng

PSU Transportation Seminars

Transit signal priority (TSP) is designed to reduce delay for transit vehicles through signalized intersections. For an existing TSP system, it is important to assess how timely and effective TSP phases are granted to buses that request priority. It is also necessary to evaluate the time savings and delays for buses and other vehicles as a result of TSP phases. However, due to the lack of disaggregated and integrated transit, traffic and signal phase data, previous studies have not investigated the TSP performance at the phase level. This study collects and integrates three archived databases: bus automatic vehicle location (AVL) …

Bicycle Tourism Plan For Economic Development: A Template For Rural Agricultural Towns And A Case Study For The City Of Winters, California, Marisa Rene Lee

Master's Theses

Bicycling is a method of tourism transportation that is healthy, non-invasive, environmentally responsible, and economically sustainable. It allows freedom, mobility, and sightseeing potential that is not made possible by other modes of transit. Thousands of bicycle tourists travel from all over the globe annually to explore California on touring bikes via established cycling routes and robust determination. Thousands of additional domestic and international visitors take weekend trips, plan family vacations, travel for business, or tour California from abroad, many of whom are excellent candidates for local and regional bicycle touring at a more gentle intensity level.
