Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …
Engaging Youth To Increase Their Transportation System Support, Understanding, And Use, Autumn Shafer, Jared Macary
Engaging Youth To Increase Their Transportation System Support, Understanding, And Use, Autumn Shafer, Jared Macary
TREC Final Reports
Little is known from research about how to motivate youth to choose non-car mobility, especially specific Portland-area youth. Understanding the current attitudes, beliefs, and behaviors of youth in relation to non-car mobility contributes to the sustainability of a long-term transportation system. Transportation system-related beliefs and behaviors of youth are likely to influence their willingness to access and support transportation services as adults. Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. Thus, it is important to develop age-appropriate messaging strategies and tactics that promote youth non-car mobility.
This project seeks to build on the sparse national and non-Portland …
Modeling Mixed Freeway Traffic: Human-Driven And Self-Driven Cars, Xianfeng Terry Yang, Zhao Zhang, Zhehao Zhang
Modeling Mixed Freeway Traffic: Human-Driven And Self-Driven Cars, Xianfeng Terry Yang, Zhao Zhang, Zhehao Zhang
TREC Project Briefs
Connected automated vehicles (CAVs) are typically equipped with communication devices (e.g., dedicated short range communications (DSRC)) and on-board sensors (e.g., Radar, Lidar, Camera, etc.). Communication devices would enable the exchange of real-time information between vehicles and infrastructures via vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) channels. Sensors equipped in vehicles are providing various vehicle sensor data (VSD) such as the CAV’s GPS location, speed and moving direction (trajectory). Existing studies have shown the effectiveness of using CAV trajectories as input in many traffic control models.
However, it can be expected that CAVs and human-driven vehicles (HVs) will co-exist on the transportation network …

Transportation Behavior Change...Now With Science!, Jessica Roberts
Transportation Behavior Change...Now With Science!, Jessica Roberts
PSU Transportation Seminars
How can we encourage people to make use of the transportation systems in place - to improve transit ridership and, in turn, to improve the health and happiness of our societies?
New findings in behavioral science could unlock new, more effective ways to change transportation behavior...but only if we have a way to find and use that evidence. TransLink (Vancouver BC) undertook a groundbreaking research effort to use cognitive biases to explain why people drive today, and and to identify possible "nudge" strategies to shift those trips to transit and active modes. The resulting report includes brand-new ideas that area …

Social marketing seeks to develop and integrate marketing concepts with other approaches to influence behaviors that benefit individuals and communities for the greater social good. Social marketing is a useful transportation demand management (TDM) planning approach to promote travel-behavior change. The purpose of this study was to explore a consumer market segmentation technique (SEGMENT) successfully used in Europe for its applicability to social marketing campaigns in the United States. Major contributions of this project are the validation of a successful existing segmentation technique for applicability in the United States, which will maximize the impact of TDM social marketing campaigns on …
Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield
Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield
PSU Transportation Seminars
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 that by lowering …

Who Wins And Who Loses? How Gentrification Caused By Public Transportation Is Felt Differently Across Race, Rosina Shipman
Who Wins And Who Loses? How Gentrification Caused By Public Transportation Is Felt Differently Across Race, Rosina Shipman
Politics Summer Fellows
When does a public good become harmful? And who does it harm? To tackle these questions I take a detailed look at how public transportation affects housing prices. Public transportation is a common good utilized by people of all different socioeconomic levels, but scholars have found that the presence of a new public transportation stop can be a catalyst for gentrification, raising housing prices and displacing previous residents. While this positive relationship between housing prices and public transportation is well documented, there is a lack of literature on how gentrification, caused by public transportation, affects neighborhood-housing prices across race. In …
How Much Do Users Value A Network Expansion? Evidence From The Public Transit System In Singapore, Eric Fesselmeyer, Haoming Liu
How Much Do Users Value A Network Expansion? Evidence From The Public Transit System In Singapore, Eric Fesselmeyer, Haoming Liu
Research Collection College of Integrative Studies
We estimate the network effects of a public transit system by examining the impact of its expansion on housing prices. Our results show that a major expansion of Singapore's Mass Rapid Transit (MRT) system increased the price of apartments within 0.5 km of a pre-expansion station by 1.8% relative to apartments that were further away from a station. Evaluated at the mean housing price, the expansion increased the value of pre-connected apartments by at least S$455 million in aggregate, which is equivalent to 9% of the estimated S$5 billion cost of the expansion.
Immigration, Income, And Public Transit Perceptions: Findings From An Intercept Survey, Jesus M. Barajas, Asha Weinstein Agrawal, Daniel G. Chatman
Immigration, Income, And Public Transit Perceptions: Findings From An Intercept Survey, Jesus M. Barajas, Asha Weinstein Agrawal, Daniel G. Chatman
Journal of Public Transportation
Although a significant fraction of public transit riders in the United States are immigrants, relatively little research explores whether immigrants have unique transit experiences. This paper analyzes intercept survey data from 1,247 transit riders in the San Francisco Bay Area to explore how mode choices and travel experiences differ for low-income immigrants compared to higher-income immigrants and US-born residents. We find that some public transit experiences are similar across all immigrant status and income groups, while in other ways low-income immigrants differ from their higher-income counterparts or from US-born respondents. In particular, low-income immigrants were less likely to have a …
Fare Policy And Vertical Equity: The Trade-Off Between Affordability And Cost Recovery, Xavier J. Harmony
Fare Policy And Vertical Equity: The Trade-Off Between Affordability And Cost Recovery, Xavier J. Harmony
Journal of Public Transportation
Vertical equity and the maximization of farebox revenue are important but conflicting goals in the development of fare policy in the United States. Reducing fares for low-income riders reduces revenue for a transit agency, while increasing fares could disproportionately impact lower-income riders. This paper details this conflict, explores strategies that could account for both goals, and evaluates fare programs in the United States. Two types of low-income strategies are discussed: first generation strategies and targeted subsidy strategies. First generation strategies have several limitations that targeted subsidy strategies account for; first generation strategies focus more on supply, while targeted subsidy strategies …

The Cost Of Jaywalking On Traffic Congestion In An Intersection In Greater Cairo: A Case Study, Hussein Gawdat
The Cost Of Jaywalking On Traffic Congestion In An Intersection In Greater Cairo: A Case Study, Hussein Gawdat
Theses and Dissertations
There have been many studies focusing on different types of traffic delays, pedestrians’ interaction at signalized intersections and economic losses as a result of these delays. However, there is a huge gap in the current literature, regionally and globally, in studying the traffic delays associated with jaywalking. In Egypt, jaywalking is considered a common phenomenon, however, population increased drastically over the past decades in Greater Cairo leading to more congested streets. This research provides a case study that investigates the economic effect of jaywalking on traffic flow in Mashaal, a sample location in Greater Cairo, due to traffic congestion. The …
A Survey Of Ride-Hailing Passengers, Steven Gehrke
A Survey Of Ride-Hailing Passengers, Steven Gehrke
PSU Transportation Seminars
In less than a decade, the ride-hailing industry, led by Uber and Lyft, has dramatically transformed the way we travel in our metro regions. Rider adoption of these on-demand mobility services has proceeded much quicker than our understanding of their impacts to our urban transportation systems. Planning for this transformation in personal mobility, which will have unintended consequences, has been made more difficult by the scarcity in meaningful data made available by these ride-hailing companies. Public agencies responsible for managing congestion and transit services are hindered in their ability to successfully plan for the integration of this emergent travel mode …

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister
Graduate Student Portfolios, Professional Papers, and Capstone Projects
The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2). …

Understanding The Effects Of Taxi Ride-Sharing: A Case Study Of Singapore, Yazhe Wang, Baihua Zheng, Ee Peng Lim
Research Collection School Of Computing and Information Systems
This paper studies the effects of ride-sharing among those calling on taxis in Singapore for similar origin and destination pairs at nearly the same time of day. It proposes a simple yet practical framework for taxi ride-sharing and scheduling, to reduce waiting times and travel times during peak demand periods. The solution method helps taxi users save money while helping taxi drivers serve multiple requests per day, thus increasing their earnings. A comprehensive simulation study is conducted, based on real taxi booking data for the city of Singapore, to evaluate the effect of various factors of the ride-sharing practice, e.g., …
A Fair Distribution Of Accessibility: Interpreting Civil Rights Regulations For Regional Transportation Plans, Karel Martens, Aaron Golub
A Fair Distribution Of Accessibility: Interpreting Civil Rights Regulations For Regional Transportation Plans, Karel Martens, Aaron Golub
Urban Studies and Planning Faculty Publications and Presentations
The US Department of Transportation requires metropolitan planning organizations (MPOs) to consider social equity in their plans and projects in accordance with civil rights–related laws. In this paper, we suggest four interpretations of directives’ distributional standards in relation to accessibility. Employing this framework, we review the equity assessments of regional plans of the ten largest MPOs in the United States. Against our expectations, we find that MPOs tend to employ relatively strong distributional standards, albeit never explicitly. We argue that more explicit guidance regarding standards would improve the fairness and consistency of planning practice

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
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 typical …

Researchers have been parsing which components of the built environment contribute to outcomes of interest and to what degree, particularly the effects on vehicle use and walking. Increasingly, researchers and practitioners recognize that the type of neighborhood may affect individual travel behaviors. These bundle of various land use and transportation system characteristics can be constructed as different neighborhood or place types. But not all place types are constructed with the same use, purpose, or methods. This presentation will review three classifications of place typologies to better understand their purpose and appropriate application as …
