Network Effects Of Disruptive Traffic Events, Juan Medina, Xiaoyue Cathy Liu

TREC Final Reports

Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g., by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non-recurrent events (e.g., crashes) can be much larger and difficult to predict, making also challenging efforts to identify, measure, and forecast their disruptive effects. This project explores a proactive approach to deploy a tool for managing non-recurrent congestion by identifying and quantifying the effects of disruptive traffic events at a microscopic level using a comprehensive set of data …

New Lidar System Pinpoints Pedestrian Behavior To Improve Eficiency And Safety At Intersections, Taylor Li, Sirisha M. Kothuri, Xianfeng Terry Yang

TREC Project Briefs

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new LiDAR system to improve data collection at intersections.

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson

Public Administration Faculty Publications and Presentations

This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

Agenda Setting And Europe's Common Immigration Policy, Jamie P. Surface

Dissertations and Theses

For over a decade the European Union has been immersed in an immigration crisis. As the desired destination for millions of people fleeing unrest in the Middle East and war in Ukraine, the EU has developed its own social, political, and humanitarian crisis. Lacking policy commonality across its member states on how to accept and manage the mass waves of migrants, the EU continues to struggle with implementing a common immigration policy. This research examines EU immigration issues, policies, and the failures of successful collaboration stymying the implementation of a standard immigration policy. Using the agenda setting model of John …

The Next Wave Of Abolishing Parking Mandates, Catie Gould, Jeannette Lee

PSU Transportation Seminars

The movement to eliminate parking mandates is having a big moment. This summer, both Oregon and California took statewide action to roll back minimum off-street parking requirements, relegalizing homes and businesses regardless of how many parking spots they have. We’ll take a look at why parking reform is so important, what to expect next in Oregon, and lessons from cities who have already gone all the way to delete this regulation from their zoning code.

Moving From Probabilistic To Time-Based On-Time Performance (For Practitioners), Miles James Allen Crumley

PSU Transportation Seminars

On-Time Performance (OTP) is a probabilistic measure that tells the customer the likelihood that the trip they are about to take will arrive "on-time." However, this metric forces the customer to think in terms of a probability of trip timeliness and not an actual time value for how timely the trip will be. This presentation will explore a new way to examine on-time performance by quantifying the timeliness of trips. Customers can then use this information to determine which trip would be the best to take based on when they need to arrive at their destination. Using a system science …

System-Level Risk Management Of Transportation Structures And Networks, David Y. Yang

PSU Transportation Seminars

Conventional risk assessment approaches in infrastructure management do not fully capture the system-level impact of structural failure or service disruption. As a result, the priorities of preservation projects may be misidentified, leading to suboptimal maintenance schedules and waste of resources. In this presentation, we will first illustrate why conventional risk assessment is not suitable for transportation structures and networks due to interdependency between assets, and then demonstrate how system-level preservation policies can be devised using novel algorithms adapted from the field of deep reinforcement learning. Results from a series of case studies showcase that the system-level risk management is essential …

How Covid-19 Changed Our Cities: Evidence From A National Survey, Deborah Salon

PSU Transportation Seminars

Human behavior is notoriously difficult to change, but a disruption of the magnitude of the COVID-19 pandemic has the potential to bring about long-term behavioral changes. During the pandemic, people were forced to experience new ways of interacting, working, learning, shopping, traveling, and eating meals. A critical question going forward is how these experiences have actually changed preferences and habits in ways that might persist. We collected a nationally-representative, 3-wave panel survey in the U.S. that aims to shed light on this question. This talk will draw from these data to describe how the pandemic did (and did not) change …

Statistical Inference For Multimodal Travel Time Reliability, Avinash Unnikrishnan, Miguel Figliozzi, Subhash C. Kochar

TREC Final Reports

Travel time reliability is a key metric of interest to practitioners and researchers because it affects travel choice and the economic competitiveness of urban areas. This research focuses on three travel time reliability metrics – buffer index, modified buffer index, and the relative width of travel time distributions. The key novel contributions of this research include using the multivariate delta method to prove that the sampling distributions of the three travel time reliability metrics are asymptotically normal. The asymptotic standard error for the three reliability metrics is derived. The asymptotic normality and the standard error result are used to arrive …

Impacts Of City-Level Parking Cash-Out And Commuter Benefits Ordinances, Gabriella Abou-Zeid, Allen Greenberg

PSU Transportation Seminars

For many workers, the decision to drive to work is an economically rational one that minimizes their commute costs. The vast majority of employers offer free workplace parking, with few in comparison offering benefits for transit, walking, biking, or other means of commuting. In effect, employers are incentivizing a behavior that increases roadway congestion, reduces physical activity, and increases emissions. Moreover, since lower-income households are less likely to own and have access to a private vehicle than moderate and higher-income households, free parking is a financial benefit that many lower-income employees cannot access.

Examining Emergency Citizen Response To The Covid-19 Pandemic: Emergent Groups Addressing Food Insecurity In Portland, Oregon, Aliza Ruth Tuttle

Dissertations and Theses

Emergency response agencies commonly focus on how hard infrastructure will interact with extreme climatic and geologic events: bridges during an earthquake and buildings following a tornado, for example. Peoples' actual experience of these extreme events vary, however, based on socially constructed consequences of natural hazard events and their interaction with a depleted or robust social safety net.

Previous research shows people living with depleted social safety nets and who experience a natural hazard event are likely to help where they see disaster. Individuals consistently form groups, called emergent groups, to organize their efforts. This research explored emergent groups that formed …
