The Role Of Bus Stop Features In Facilitating Accessibility, Keith Bartholomew, Ja Young Kim, Divya Chandrasekhar, Reid Ewing, Arlie Adkins, Samuel Jensen

TREC Final Reports

Although transit decision-makers and riders generally favor improving bus stops by adding shelters, benches, and similar features, it is unclear the impact such features have on transit demand and there has been little research that measures these impacts. This study examines the link between stop improvements and changes in stop-level boardings on scheduled-service buses and in ADA paratransit demand in the Salt Lake City, UT, metropolitan area between 2014 and 2017. The study also investigates current bus stop improvement practices of leading transit agencies nationwide. The study uses a number of quantitative and qualitative techniques, including propensity score matching, propensity …

The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership: Analysis Of Multifamily Residents In Portland, Oregon, Edgar Bertini Ruas

Dissertations and Theses

Since the beginning of the 21st Century, the world has seen the rapid development of the so-called "sharing economy" or collaborative consumption (Botsman, 2010). One of the first areas affected by the shared economy is vehicle ownership. With the emergence of several new providers of mobility services, such as Uber and car2go, there has been the promise of changes to the traditional way of owning and using a vehicle (Wong, Hensher, & Mulley, 2017). One potential consequence of shared mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing …

Transferability & Forecasting Of The Pedestrian Index Of The Environment (Pie) For Modeling Applications, Kelly Clifton, Jamie Orrego-Onate, Patrick Allen Singleton, Robert J. Schneider

TREC Final Reports

This project focuses on making our measures, models, and methods more transferable to other locations. Specifically, we re-evaluate, compare and test our pedestrian index of the environment (PIE) measure using data resources more commonly available to planning agencies across the country. Next, we test the results of PIE and its input data in models of pedestrian mode choice for stability of estimation results within a region (intraregional) and between regions (interregional). This research is the next logical step in the MoPeD’s enhancement and is critical to enabling its utility beyond the Portland region. The results of this project show that …

Webinar: Segmenting The Market For Transportation Demand Management Campaigns, Philip L. Winters, Amy Lester

TREC Webinar Series

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. It 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 successfully used in Europe for its applicability to marketing efforts in the United States. Attitudinal and demographic data were collected from 1900 individuals in Florida, Oregon, and Virginia modeled after the European approach. Clustering analysis was applied to divide the sample into segments so that members of …

Portland’S Transportation Wallet: How Pricing Parking Can Create New Mobility Options, Sarah Goforth

PSU Transportation Seminars

The Transportation Wallet is one of Portland’s newest parking and transportation demand management (TDM) strategies, designed to reduce parking demand while simultaneously offering new mobility options by bundling transit and bike share passes into one consumer product. Two of Portland’s managed parking districts have elected to add a surcharge to the cost of on-street parking permits, a portion of which is used to subsidize the cost of the Transportation Wallet. Residents and employees in the parking districts are eligible to purchase the Transportation Wallet at a fraction of the retail cost. As an added incentive to increase parking supply, people …

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 …

Webinar: Transportation Benefits Of Parking Cash-Out, Pre-Tax Commuter Benefits, And Parking Surtaxes, Allen Greenberg, James Choe, Sonika Sethi, Colleen Stoll

TREC Webinar Series

The vast majority of employers provide their employees free parking at work, which encourages employees to drive alone. Multiple strategies exist to level the playing field between travel modes and allow employees to select the travel option most beneficial to them without suffering a financial penalty. The U.S. Department of Transportation, Federal Highway Administration sponsored a study to understand the effect parking cash out, pre-tax commuter benefits, and parking surtaxes can have on congestion, emissions, and other driving-related externalities. The study is part of the Administration’s ongoing efforts to increase awareness of solutions to address the transportation issues affecting communities …

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 …

Network Congestion Effect Of E-Hailing Transportation Services, Xuegang Ban

PSU Transportation Seminars

E-hailing plays a key role in emerging transportation services such as ridesourcing, ridesharing and taxis, among others. This seminar will present a general economic model to analyze the congestion effect of e-hailing services in a transportation network.

The model can help analyze customers’ choices of different modes, based on their value of time and the charging schemes of different services, as well as the overall impact of the services to network level congestion.

Assessing Travel Plans For Residential Developments, Geoff Rose

PSU Transportation Seminars

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 …

The Sfpark Pilot: Using Data To Make Cities Better, Kathryn Doherty-Chapman

PSU Transportation Seminars

SFpark was a federally-funded pilot program of a new approach to managing parking in San Francisco. It utilized real time data to identify parking availability, and demand-responsive parking pricing to help make parking easier to find. Parking management is an invaluable transportation demand management tool and the SFpark pilot demonstrated how data can help cities make smarter decisions. Come hear about the pilot evaluation results from a former SFpark staffer and PSU alum.

Development And Sensitivity Testing Of Alternative Mobility Metrics, John Gliebe, James G. Strathman

Urban Studies and Planning Faculty Publications and Presentations

The Oregon Highway Plan’s (OHP) mobility policies guide various planning and programming activities of the Oregon Department of Transportation (ODOT). Among these activities are ODOT’s land use change review responsibilities under the Transportation Planning Rule, as adopted by the state’s Land Conservation and Development Commission. This report examines supplemental transportation performance metrics beyond the volume-to-capacity metric that currently supports OHP mobility policies. Selected supplemental metrics are empirically analyzed using a travel demand model calibrated for a Medford, Oregon study area.

Effective Transportation Demand Management: The Results Of Combining Parking Pricing, Transit Incentives, And Transportation Management In A Commercial District Of Portland, Oregon, Martha J. Bianco

Center for Urban Studies Publications and Reports

The Lloyd District is a high-density commercial and residential district located a short distance from downtown Portland, Oregon. Parking and transportation problems in the District have been a source of increasing contention for nearly a decade. As a result. in September of 1997. the City of Portland implemented a Lloyd District Partnership Plan, which consists of a number of elements aimed at curbing SOY use for the commute to and from the District. This plan included parking pricing in the form of meters, w'here on-street parking had previously been free: discounted transit passes: and other transportation demand management (TOM) strategies. …
