Public Transportation Accessibility, Proximity To New York City, And Residential Property Values In New Jersey, Sangwan Lee, Michael Smart May 2020

Public Transportation Accessibility, Proximity To New York City, And Residential Property Values In New Jersey, Sangwan Lee, Michael Smart

Hatfield Graduate Journal of Public Affairs

In recent years as housing with better transit accessibility has become unaffordable to many households in many regions globally, the call to study the connection between transit and property values has shifted to concern itself with the negative consequences of transit access being capitalized into property values. The primary purpose of this research is to define the effect of station proximity and other characteristics on housing prices and provide evidence if there is displacement in the area with better accessibility to transit. The outcome reveals that locational factors are associated with housing prices. Inherent housing features, the number of beds ...

Webinar: Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang May 2020

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 ...


Pig Iron To Wrought Iron: Lake Oswego's Transformation From Iron Smelting To The Privatization Of Oswego Lake, Mathew K. Ragsdale Apr 2020

Pig Iron To Wrought Iron: Lake Oswego's Transformation From Iron Smelting To The Privatization Of Oswego Lake, Mathew K. Ragsdale

Young Historians Conference

The paper focuses on the interaction between Oregon's public trust doctrine, city ordinances, and private interests surrounding access to Oswego Lake. Areas of study include the early development of Lake Oswego with its prominence in the Oregon iron industry, and its transition from industrial town to weekend retreat to affluent suburb between the late 1800s and mid 1900s. The Lake Oswego Corporation has claimed power over all aspects of the lake, a notion disputed by Oregon's strong public trust doctrine. The city, whose duty is to all residents, has used the lake as a public asset while restricting ...


Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong Apr 2020

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

TREC Friday Seminar Series

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 ...

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

TREC Friday Seminar Series

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 facilities ...

Webinar: New Travel Demand Modeling For Our Evolving Mobility Landscape, Reid Ewing, Sadegh Sabouri Feb 2020

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 ...

When Growth Outpaces Infrastructure: Access To Opportunities In Suburban Boomtowns, Jandel Crutchfield, Courtney Cronley, Kate Hyun

TREC Project Briefs

In the last twenty years, the population increased over 100% in Collin County, Texas. The county is projected to have over 2.4 million residents by 2050 -- more than three times its population in 2010. When enough people flock to an area to call it a boomtown, the population tends to grow much faster than the infrastructure to support it. Where does that leave mobility options for residents? Researchers from the University of Texas at Arlington’s (UTA) School of Social Work and College of Engineering partnered with the Collin County Homeless Coalition (CCHC) to investigate gaps in transportation services ...

Webinar: Letting Bike Riders Catch The Green Wave, Stephen Fickas, Marc Schlossberg Dec 2019

Webinar: Letting Bike Riders Catch The Green Wave, Stephen Fickas, Marc Schlossberg

TREC Webinar Series

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.

This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on ...
