Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub Apr 2019

Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub

TREC Project Briefs

Since 1994, every Federal agency has a mandate to develop a strategy for identifying and addressing disproportionately high and adverse human health or environmental effects on low income populations and minority populations. In transportation planning this means including those communities’ voices in the planning process, and evaluating the social impacts early on.

A new report from the Federal Highway Administration (FHWA), prepared by Portland State University and ICF International, provides an in-depth analysis of national demographic trends and a synthesis of best long-range planning practices borne out of five case studies


Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain Feb 2019

Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain

TREC Webinar Series

Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion of everyone we are supposed to serve as transportation professionals.


The Success Of An Integrated Mobility Strategy: Lessons From The Netherlands For The Pacific West Coast, Lucas Van Der Linde Feb 2019

The Success Of An Integrated Mobility Strategy: Lessons From The Netherlands For The Pacific West Coast, Lucas Van Der Linde

TREC Friday Seminar Series

The Netherlands sets the standard for their multimodal connectivity. It has world's highest use of cycling and an integrated mobility network with an efficient transport system. During this seminar, Lucas will tell more about the Dutch Approach and how this could be applied to the American transportation context.

Lucas will use the case of the Bay area to show this. The Bay Area in California currently faces massive challenges in transportation because of the enormous growth of the region. With the use of a new innovative modelling tool, the Move Meter (http://www.movemeter.com/), Lucas will show the ...

Addressing Changing Demographics In Environmental Justice Analysis, State Of Practice, Aaron Golub, Les Brown, Michael Grant, Nathan Mcneil, Charles Ryerson, Matt Gray, Stephanie Lonsdale, Madison Levy

TREC Final Reports

This report documents how metropolitan planning organizations (MPO), State departments of transportation (DOT), and other transportation agencies are adapting Environmental Justice (EJ) analysis techniques to understand transportation impacts in communities undergoing rapid demographic change. The report also highlights national demographic trends, showing significant change in the size and location of low-income and minority households. These changes are documented in a series of State- and county-level maps demonstrating absolute and percent change in minority populations, low-income populations and limited English proficiency populations between the 1990 – 2010 decennial census periods. Based on the state of practice review, the report also highlights strategies ...


Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield Sep 2018

Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield

TREC Friday Seminar Series

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found ...


Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub Feb 2018

Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

This study investigates the impacts of positive and negative externalities of highways and light rail on commercial property values in Phoenix, Arizona. We hypothesize that the positive externality (i.e., accessibility) of highway and light rail accrues at exits and stations, whereas nodes and links of highways and light rail emanate negative effects. Positive and negative effects decay with increasing distance and are captured by multiple distance bands. Hypotheses are tested using a spatial error regression model. Results show that commercial property values are positively and significantly associated with the accessibility benefits of transport nodes. The distance-band coefficients form a ...


Active And Public Transportation Connectivity Between North Temple Tod And Jordan Park River Trail, Ivis Garcia Zambrana, Christie Oostema Oct 2017

Active And Public Transportation Connectivity Between North Temple Tod And Jordan Park River Trail, Ivis Garcia Zambrana, Christie Oostema

TREC Final Reports

The project seeks to capitalize on existing community assets—several TOD stations and a regional bike and pedestrian trail system—by studying how these can be linked. The overarching goal of this project is to increase scholarship on networking safe routes that can encourage public and active transportation choices and thus, encourage a healthier lifestyle and advance sustainability. By expanding pedestrian, bicycle and transit connections to green space and offering the most potential for TOD, this proposal clearly demonstrates the greatest priorities of NITC. Moreover, nationwide, communities like Salt Lake’s West Side are in greater need of sustainable transportation ...


Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo Sep 2017

Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo

TREC Webinar Series

Parking is a serious issue in many urban areas, especially those experiencing rapid population growth. To address this problem, some cities have implemented demand-responsive pricing programs, where parking prices vary depending on the occupancy rate in a previous period. Yet, few empirical studies have rigorously evaluated these programs. In this study, we investigate the impacts of SFpark, a demand-responsive pricing parking program in San Francisco that began in 2011. We observe effects on three important aspects of urban transportation: parking availability, transit bus ridership and congestion. The timing of this program is plausibly exogenous to factors that affect these outcomes ...


How Does Transportation Affordability Vary Among Tods, Tads, And Other Areas?, Brenda Scheer, Reid Ewing, Keunhyun Park, Shabnam Sifat Ara Khan Aug 2017

How Does Transportation Affordability Vary Among Tods, Tads, And Other Areas?, Brenda Scheer, Reid Ewing, Keunhyun Park, Shabnam Sifat Ara Khan

TREC Final Reports

Transit-oriented development (TOD) has gained popularity worldwide as a sustainable form of urbanism; it concentrates development near a transit station so as to reduce auto-dependency and increase ridership. Existing travel behavior studies in the context of TOD, however, are limited in terms of small sample size, inconsistent TOD classification methods, and failure to control for residential self-selection. Thus, this study has three research questions. First, how can we distinguish between Transit-oriented development (TOD) and Transit-adjacent development (TAD)? Second, how do travel behaviors vary between TODs and TADs? Third, how does transportation affordability vary between TODs and TADs? This study utilizes ...


When Cities Shrink, Affordability Does Too, Joanna Ganning, Jenna Rosie Tighe Jul 2017

When Cities Shrink, Affordability Does Too, Joanna Ganning, Jenna Rosie Tighe

TREC Project Briefs

To better understand the real costs of housing and transportation in a declining urban context, NITC researchers implemented a household survey to determine whether the assumptions made in existing research literature and in the LAI regarding household expenditures and transportation accessibility hold true when analyzing shrinking cities—generally, cities characterized by a long-term loss in occupied housing units. The project was led by Joanna Ganning of Cleveland State University, who has conducted previous research into shrinking cities with the support of the NITC program.


Homes Close To Fast Transit: The Value Is Still Rising, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran Jul 2017

Homes Close To Fast Transit: The Value Is Still Rising, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran

TREC Project Briefs

This research contributes to the relatively small body of literature on property value impacts of BRT in the U.S. by conducting a case study on Lane Transit District’s EmX BRT service in Eugene, Oregon, using econometric modeling techniques to estimate changes in property values associated with the BRT. The analysis is based on hedonic price regression analysis, where sale prices are modeled using several property characteristics that contribute to the market or sale price. The findings of this research indicate that the EmX BRT system does positively impact surrounding single-family home sale prices.


What Do We Know About Location Affordability In U.S. Shrinking Cities?, Joanna Ganning, Jenna Rosie Tighe Jul 2017

What Do We Know About Location Affordability In U.S. Shrinking Cities?, Joanna Ganning, Jenna Rosie Tighe

TREC Final Reports

In late 2013, the Department of Housing and Urban Development (HUD) launched the Location Affordability Index (LAI) portal. Their dataset uses models to estimate typical amount households spend on housing and transportation at the block group level, and calculates “H + T Affordability,” the percent of household income spent on these items. In our previous research, we analyzed 81 shrinking cities to determine how location affordability differs across various neighborhoods. Our results suggest that households in declining neighborhoods, as compared to stable or redeveloping neighborhoods, face the greatest H + T affordability challenges in shrinking cities. Furthermore, in declining neighborhoods, virtually all ...


Impacts Of Bus Rapid Transit (Brt) On Surrounding Residential Property Values, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran Jul 2017

Impacts Of Bus Rapid Transit (Brt) On Surrounding Residential Property Values, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran

TREC Final Reports

As bus rapid transit (BRT) grows in popularity in the United States, a better understanding of the mode’s impacts on land uses and property values is needed. Economic theory suggests, and literature has shown, that people are willing to pay higher housing costs to lower their costs of transportation to areas of economic activity. Does high-quality BRT service reliably provide such access and, thereby, increase residential property values? The hypothesis is that property values are higher closer to BRT stations, reflecting a premium for the access provided by the BRT service to various goods, services, employment, education, and recreation ...


Annual Metro Regional Trail Count And Why Local Extrapolation Factors Matter, Geoff Gibson May 2017

Annual Metro Regional Trail Count And Why Local Extrapolation Factors Matter, Geoff Gibson

TREC Friday Seminar Series

Metro, Portland's regional governing agency, conducts annual two-hour counts along its regional trail every September. This upcoming fall (2017) will be the 10th year that the counts have been held, which means we at Metro can finally start seeing noticeable, long-lasting trends in the regional trail network. Perhaps more importantly, we are seeing how these data have directly impacted investments in future trail, bicycle, and pedestrian projects.

This seminar will cover the history of the program, details of how it's conducted and why it's conducted that way, how data are used (including an inside look at future ...


Addressing Data Challenges For Bicycle Crash Analysis, Eleni Christofa Mar 2017

Addressing Data Challenges For Bicycle Crash Analysis, Eleni Christofa

TREC Friday Seminar Series

Although an increasing number of separated bicycle facilities have been appearing across the US over the last few years, the majority of bicyclists are still traveling on roadways shared with motorized vehicles.

As a result, bicycles are essentially double exposed to safety risk, due to their interactions with both motorized vehicles and other bicycles. In addition to this double exposure, data challenges–such as a lack of continuous counts and bicycle crash data—complicate the assessment of bicycle safety further.

This research presents a bicycle crash analysis framework for estimating bicycle crash rates accounting for both bicycle and motorized vehicle ...


Impact Of Bike Facilities On Residential Property Prices, Wei Shi Feb 2017

Impact Of Bike Facilities On Residential Property Prices, Wei Shi

TREC Friday Seminar Series

As many cities are investing in street improvement or transportation infrastructure upgrade projects to provide better bike access or more complete bike networks, the economic value of bike infrastructure and bike facilities remains an area where many practitioners, planners and policy makers are seeking more conclusive evidence. Using residential property values as indicators of consumer preferences for bicycle infrastructure, this study focuses on advanced bike facilities which represent higher levels of bike priority or bike infrastructure investments that have been shown to be more desirable to a larger portion of the population. Estimating ordinary least squares hedonic pricing models and ...


Trip And Parking Generation At Transit-Oriented Developments, Reid Ewing, Guang Tian, Torrey Lyons, David Proffitt, Preston Stinger, Rachel Weinberger, Ben Kaufman, Kevin Shivley Jan 2017

Trip And Parking Generation At Transit-Oriented Developments, Reid Ewing, Guang Tian, Torrey Lyons, David Proffitt, Preston Stinger, Rachel Weinberger, Ben Kaufman, Kevin Shivley

TREC Final Reports

The decision of how best to allocate land around transit stations is a debated topic, with transit officials often opting for park-and-ride lots over active uses such as multifamily housing, office, and retail organized into transit-oriented developments (TODs). In practice, guidelines for providing parking and mitigating vehicle trips come mainly from the Institute of Transportation Engineers (ITE) Trip Generation Manual and the ITE Parking Generation Manual. However, both manuals have well-known shortcomings. The goal of this study is to determine how many fewer vehicle trips are generated at TODs, and how much less parking is required at TODs, than ITE ...


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

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 ...


Webinar: The Association Between Light Rail Transit, Streetcars And Bus Rapid Transit On Jobs, People And Rents, Arthur C. Nelson Nov 2016

Webinar: The Association Between Light Rail Transit, Streetcars And Bus Rapid Transit On Jobs, People And Rents, Arthur C. Nelson

TREC Webinar Series

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 ...


Planning Transportation For Recreational Areas, Anne Dunning Oct 2016

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.


Understanding Where We Live And How We Travel, Kristina Marie Currans Oct 2016

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

TREC Friday Seminar Series

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 ...


Can Location Value Capture Pay For Transit? Organizational Challenges Of Transforming Theory Into Practice, Deborah Salon Oct 2016

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

TREC Friday Seminar Series

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 ...


Developing A Model For Transit Oriented Development In Latino Immigrant Communities: A National Study Of Equity And Tod, Gerardo Francisco Sandoval Sep 2016

Developing A Model For Transit Oriented Development In Latino Immigrant Communities: A National Study Of Equity And Tod, Gerardo Francisco Sandoval

TREC Final Reports

This research project is a continuation of a previous NITC-funded study. The first study compared the MacArthur Park TOD in Los Angeles to the Fruitvale Village TOD in Oakland. The findings from this new study further validate the key findings from the first study. This new comparative case study analyzed the extension of Los Angeles’ Gold Line into Boyle Heights and the revitalization linked to Boyle Heights due to two TODs built in that neighborhood. I conclude from all four cases that TODs can help serve as catalysts for neighborhood revitalization in low-income communities by paying attention and building upon ...

Is It Working? Are The Region's And City's Transportation Policies And Actions Moving Us In Their Desired Directions?, Roger Geller May 2016

Is It Working? Are The Region's And City's Transportation Policies And Actions Moving Us In Their Desired Directions?, Roger Geller

TREC Friday Seminar Series

The City of Portland and the Metropolitan Region have strong policies in place to encourage transportation through means other than the single-occupancy vehicle. Both governments have numeric goals for the proportion of trips to be made by walking, bicycling, transit, shared vehicles, working at home and driving alone. Indeed, the City of Portland desires that by 2035 no more than thirty percent of commute trips be made by people driving alone. Similar policies have driven transportation planning in the city and region for decades.

To understand if these policies will be effective it's necessary to understand whether their antecedents ...


Measuring What We Value: Using Performance Measures To Achieve Goals, Chris Rall May 2016

Measuring What We Value: Using Performance Measures To Achieve Goals, Chris Rall

TREC Friday Seminar Series

Performance measures are commonly used in transportation planning, but how effectively are public agencies using them, and to what ends?

Metro, ODOT and many cities use performance measures to evaluate investment choices and monitor progress. Drawing from Transportation for America’s report Measuring What We Value, and some of the most cutting edge examples of performance-based planning around the nation, Chris' presentation will step back to consider what makes a performance-based planning approach effective at achieving an agency’s goals.


Consistent Estimation Of Route Choice Models For Dynamic Transit Assignment, Jeff Hood Feb 2016

Consistent Estimation Of Route Choice Models For Dynamic Transit Assignment, Jeff Hood

TREC Friday Seminar Series

Dynamic transit assignment models have the potential to improve local transportation agencies’ capability to forecast the demand for public transit facilities under conditions of limited capacity or varying reliability. In order to be useful in practice, the simulated route choices of passengers in these models need to reflect the behavior of actual residents observed in local travel surveys. Most analysis methods of revealed route choice preferences developed to date have either (1) not been proven to provide consistent estimates or (2) required an untenable computation time for practical applications. Furthermore, no model of transit route choice has accounted for variability ...


Towards Effective Design Treatment For Right Turns At Intersections With Bicycle Traffic, David Hurwitz, Christopher Monsere Feb 2016

Towards Effective Design Treatment For Right Turns At Intersections With Bicycle Traffic, David Hurwitz, Christopher Monsere

TREC Friday Seminar Series

The overall goal of this research was to quantify the safety performance of alternative traffic control strategies to mitigate right-turning-vehicle/bicycle collisions, often called "right-hook" crashes, at signalized intersections in Oregon.

A two stage experiment was developed in the OSU high-fidelity driving simulator to investigate the causal factors of right-hook crashes at signalized intersections with a striped bike lane and no right-turn lane, and to then identify and evaluate alternative design treatments that could mitigate the occurrence of right-hook crashes.

Experiment 1 investigated motorist and environmental related causal factors of right-hook crashes, using three different motorist performance measures: (1) visual ...


Assessing Travel Plans For Residential Developments, Geoff Rose Jan 2016

Assessing Travel Plans For Residential Developments, Geoff Rose

TREC Friday Seminar Series

A ‘travel plan’ is a travel demand management strategy that contains a package of site-specific measures designed to manage car use and encourage the use of more sustainable transport modes. Much of the existing literature on travel plans focuses on their application in workplaces and schools. Travel plans can be required for new residential developments as part of the land use planning and approvals process. However, there is limited understanding of the extent to which they have influenced travel behaviour. This presentation focuses on the assessment of travel plans developed for new residential apartment developments in Melbourne, Australia. Consideration is ...
