Winning The Fight For Better Bus Service, Steven Higashide

PSU Transportation Seminars

The "right to the city" depends on the right to access the city, and U.S. regions are marked by profoundly unequal access. One of the clearest manifestations of this is the state of U.S. bus transit. Bus service is simple to improve and has vast potential to better people's lives, but has been constrained by the racist planning and politics that shape every American city.

How can we fulfill the promise of better buses and create abundant transit networks that expand access to opportunity? In this seminar, Higashide unpacks the elements of effective bus service – and cites examples from …

Racial Disparities In Traffic Enforcement, Mike Dolan Fliss

PSU Transportation Seminars

Law enforcement traffic stops are one of the most common entryways to the US justice system, with significant downstream impacts for both individuals and communities. Group-specific rates are typically based on jurisdiction resident populations; these rates, like many justice-system indicators, demonstrate race-ethnicity disparities. Residential-based rates implicitly assume race-ethnicity groups have equal vehicle access, equal driving volume, and that all driving occurs in resident’s jurisdictions. In contrast, surveys suggest Black non-Hispanic and Hispanic households have less access and drive less than white non-Hispanic households. Models incorporating US Census data and race-ethnicity driving factors from the 2017 National Household Travel Survey showed …

Curating Equitable Transportation, Nikotris Perkins

PSU Transportation Seminars

Getting people and goods from here to there is central to the ways we live, work, and play in the United States. The transportation networks we create as planners, engineers, geologists, contractors, consultants, advocates, and citizens involve a multitude of decisions. These decisions have great impact on who can get where, when and how; often connected to our structures of social power. This seminar connects those dots, questions our ability to make change, and calls participants to be actively involved in a transportation system that is curated for those it targets: everyone.

Webinar: Bus Stops: Access And Equity, Keith Bartholomew

TREC Webinar Series

Improving bus stops by providing shelters, seating, signage, and sidewalks is relatively inexpensive and popular among riders and local officials. Making such improvements, however, is not often a priority for U.S. transit providers because of competing demands for capital funds and a perception that amenities are not tied to measurable increases in system effectiveness or efficiency. This webinar focuses on the role that bus stops play as the point of first contact between transit agencies and their potential riders, and how the quality of that contact can influence both ridership and accessibility for riders with mobility-related disabilities. The webinar will …

At The Intersection Of Safety + Race + Transportation, Charlene Mcgee

PSU Transportation Seminars

Transportation policies at the local, regional, state and national levels have a direct impact on urban land use and development patterns. Transportation intersects with multiple areas including public health, education, climate change, physical activity, health outcomes, build environment, violence, safety, social cohesion and the wellness of communities. For the health outcomes influenced by transportation, disparities exist by race, ethnicity, and socioeconomic status in Multnomah County. Disproportionate exposure to injury, air pollution, and noise contributes to inequitable burdens of injuries and chronic disease among race and ethnic groups. This is exacerbated by lack of access to safe places for active transportation …

Case Studies Of Travel Demand Analysis On Transport Disadvantaged Communities, Tierra Bills

PSU Transportation Seminars

Travel Demand Models are the backbone of decision-making for public transportation infrastructure investment. Yet, critiques of these models with respect to their usefulness and performance for transport disadvantage communities are rare in the academic literature. These disadvantage communities may include (but are not limited to) low income travelers, transit dependents, un/underemployed, and the elderly. With the objective of promoting travel demand models that are better equipped for assessing transportation impacts for disadvantaged communities, this presentation highlights lessons learned from two case studies of applying travel demand analysis to understand the transportation accessibility of low income, elderly, and transit dependent communities. …

Biking While Black: How Planning Contributes To Unjust Policing, Jesus Barajas

PSU Transportation Seminars

Neighborhoods of color tend to be the most dangerous places for cyclists and other road users, a result in part of historic disinvestment and failure to provide basic infrastructure. Safety efforts to reduce crashes, like Vision Zero, have called for both increased investment, a qualified benefit for disenfranchised communities, and increased traffic enforcement, a response that is likely to place people of color in even greater harm based on extensively documented police injustice.

• For more about the problems of policy and planning around 'bicycling while black,' check out a Sept 9, 2020 blog post by Jesus Barajas.

Webinar: Findings From 15 Years Of Travel Surveys At Portland Area Transit-Oriented Developments (Tods), Jennifer Dill, Nathan Mcneil

TREC Webinar Series

Since 2005, Portland State University has periodically surveyed occupants of recently developed higher-density and mixed-use projects near transit, often referred to as Transit-Oriented Developments (TODs). The general objectives of the surveys were to better understand actual transit use, among other factors, of residents in these buildings. Between 2005 and 2018, the research team surveyed residents of nearly 50 TODs. With funding from Metro and the National Institute for Transportation and Communities, the research team carried out a two-pronged study drawing on this wealth of data. First, we explore geographic differences within the Portland region in terms of travel behavior and …

Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub

PSU Transportation Seminars

As transit agencies modernize their fare payment systems, opportunities to pay with cash are reduced. This speeds boarding and lowers the cost of operations while also creating new sources of ridership data. Arguably, service is improved for riders as well as payment systems could work across modes, creating a more seamless and simplified experience. Still, about 15% of adults in the United States are without a bank account or credit card account and many rely on restrictive cell-phone data plans or don’t have access to a smartphone. These shares are even higher for public transit users. These un- and under-banked …

Webinar: Natural Pozzolans In The Pacific Northwest And Their Beneficial Uses, Matthew D. Sleep

Webinar: Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang

TREC Webinar Series

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the …

Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong

PSU Transportation Seminars

Prior studies show that transit-oriented developments (TODs) increase property values and raise property tax revenue. Property owners reap economic benefit from TODs and public officials use it as evidence to justify the high cost of rail transit. However, renters, who rely on transit more than homeowners, may have to pay higher rent to live in TODs. The location affordability index at the neighborhood level suggests that renters can also benefit from TOD by saving money on transportation costs. Recent studies at the individual level, however, found little evidence that living in TODs reduces transportation expenditure. Using rental data scraped from …

Webinar: Visual Exploration Of Trajectory Data, Nikola Markovic, Mark Franz, Seth Miller

TREC Webinar Series

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures.

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier

PSU Transportation Seminars

This seminar is brought to you by the Oregon chapter of the Association of Pedestrian and Bicycle Professionals (APBP), with support from TREC at Portland State.

Transit stops and stations are a confluence of complementary and competing activities - pedestrians accessing businesses, passengers boarding and alighting, and bicyclists zipping through to their destinations. People are moving in different directions, at different speeds, and need to be able to navigate this space safely and comfortably. A common point of conflict is the bus/bicycle interaction when a transit stop is adjacent to a bike lane. Designs for integrating pedestrian and bicycle …

These e-grocers are reviewed in terms of service areas, pricing, and inventory choice, as these are key factors …

Webinar: New Travel Demand Modeling For Our Evolving Mobility Landscape, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

Conventional four-step travel demand models are used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies, as the basis for long-range transportation planning in the United States. A flaw of the four-step model is its relative insensitivity to the so-called D variables. The D variables are characteristics of the built environment that are known to affect travel behavior. The Ds are development density, land use diversity, street network design, destination accessibility, and distance to transit. In this seminar, we will explain how we developed a vehicle ownership model (car shedding model), an intrazonal travel …
