Office Rent Premiums With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing 2015 University of Utah

Office Rent Premiums With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

It seems an article-of-faith that real estate markets respond more favorably to location within one-half mile of transit stations. Planning and public decision-makers have thus drawn half-mile (or smaller) circles around rail transit stations assuming larger planning areas would not be supported by the evidence. Recent research, however, has shown market-responsiveness well beyond one-half mile. We contribute to this literature by evaluating the distance-decay function of office rents in metropolitan Dallas and Denver with respect to light rail transit (LRT) station distance. Using a quadratic transformation of distance we find office rent premiums extending in the range of two miles …


Standardization Of Highway Construction Delay Claim Analysis: A Highway Bridge Case Study, Mohammed S. Hashem M. Mehany, Neil S. Grigg 2015 Missouri State University

Standardization Of Highway Construction Delay Claim Analysis: A Highway Bridge Case Study, Mohammed S. Hashem M. Mehany, Neil S. Grigg

Journal of Transportation Management

Highway construction efficiency is critical to highway users such as the trucking industry given today’s era of shortages in funding, and given the need for major re-investments in the highway system. One topic that can add to project costs relates to delays and how contractors are reimbursed for such delays. Delays are common in construction, especially in complex heavy highway and other infrastructure projects, and the claims they generate have negative effects on project schedules and costs. In spite of this, the analysis of claims is hindered due to the variety of methods and analysis techniques in use and lack …


A New Approach To Speaker Relevence Using A Logistics Executive In Residence Course, Stephen M. Rutner, Scott R. Cox, Maria E. Aviles 2015 Georgia Southern University

A New Approach To Speaker Relevence Using A Logistics Executive In Residence Course, Stephen M. Rutner, Scott R. Cox, Maria E. Aviles

Journal of Transportation Management

This article addresses a new method to bring real world relevance into the Logistics, Transportation and Supply Chain Management classroom. A different type of Executive in Residence course focuses on using multiple industry speakers to provide a unique learning environment for today’s Millennial majors. While the majority of the paper is a thought based overview, a statistical analysis of student responses was used to compare various types of relevant courses. A simple comparison of various appropriate items was examined to identify if the Executive in Residence course increased learning. Both the anecdotal and statistical evidence suggests that the Executive in …


Feasibility Analysis And Strategic Measures For Promoting Viable New Urban Development, Elizabeth J. Farr 2015 Claremont McKenna College

Feasibility Analysis And Strategic Measures For Promoting Viable New Urban Development, Elizabeth J. Farr

CMC Senior Theses

This thesis demonstrates that New Urbanism is both an advisable and feasible method for reducing carbon emissions to mitigate global climate change. New Urban areas commonly generate lower carbon emissions compared to conventional suburban development due to lower car use and higher levels of walking and use of other forms of transportation. Economic and political feasibility of New Urban development is determined by analyzing case studies, housing price premia, financing, and fiscal impact. The many contexts and perspectives involved in the planning process are analyzed to determine if New Urbanism is advisable in the larger setting in which developers, advocates, …


Integrating Truck Emissions Cost In Traffic Assignment, Peter Foytik, R. Michael Robinson 2015 Old Dominion University

Integrating Truck Emissions Cost In Traffic Assignment, Peter Foytik, R. Michael Robinson

VMASC Publications

The adverse impacts of greenhouse gasses (GHG) and the imperative for reducing the existing rate of GHG production are well established. In the United States, the largest source of GHG emissions from human activities is from burning fossil fuels, primarily for the generation of electricity and transportation. The transportation sector accounts for 28% of all U.S. GHG production. Heavy-duty vehicles, such as large freight trucks, account for nearly one-fifth of the U.S. total, and this fraction is expected to grow rapidly. Consequently, many efforts are being used to reduce the total emissions of freight trucks. Most efforts emphasize one of …

Crash Frequency Analysis Of Left-Side Merging And Diverging Areas On Urban Freeway Segments: A Case Study Of I-75 Through Downtown Dayton, Ohio, Deogratias Eustace, Aline Aylo, Worku Y. Mergia

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This paper analyzes the effect of left- and right-side merging and diverging areas and other variables such as light condition, roadway pavement condition, drivers’ age and presence of construction work zones on the occurrence frequency of crashes. A 6.5-mile (10.5-km) section of I-75 that passes through downtown Dayton, Ohio was considered. The area of interest has a high traffic volume and consists of different geometric design challenges including closely spaced merging and diverging ramps. A four-year record of crash data (2005–2008) and a statistical modeling technique that assumes a negative binomial distribution on generalized linear models (GLMs) were used to …


The Effects Of Discussion And Information On Public Support For Tax And Fee Increases For Transportation, Juita-Elena Yusuf, Lenahan O'Connell 2015 Old Dominion University

The Effects Of Discussion And Information On Public Support For Tax And Fee Increases For Transportation, Juita-Elena Yusuf, Lenahan O'Connell

School of Public Service Faculty Publications

This research note compares the effect on willingness to raise taxes and government fees of three common approaches to public consultation: (a) a telephone survey with no information or discussion, (b) a focus group with discussion but no information relating need to the proposed tax or fee, and (c) a focus group with discussion and such information. Our purpose is twofold: (a) illustrate the contribution of pertinent information to public acceptance of tax or fee increases, and (b) suggest a more comprehensive and informative approach to consultation with the public. We do so using the examples of raising the gas …


Exploring A Toll Auction Mechanism Enabled By Vehicle-To-Infrastructure Technology, Andrew J. Collins, Erika Frydenlund, R. Michael Robinson, Mecit Cetin 2015 Old Dominion University

Exploring A Toll Auction Mechanism Enabled By Vehicle-To-Infrastructure Technology, Andrew J. Collins, Erika Frydenlund, R. Michael Robinson, Mecit Cetin

VMASC Publications

High-occupancy toll (HOT) lanes—an increasingly popular solution for congested roadway networks—give drivers the option to access express lanes. The cost of entry often varies with demand, although no standard method of optimizing these price points exists. Using the principles of a Vickrey auction that incentivizes true-value bids, this paper proposes a tolling system that uses vehicle-to-infrastructure technology to optimize toll operator revenue with HOT lane usage. In the scenario, a roadway network consists of a HOT lane and a general-purpose lane, each with identical physical properties. Drivers can access the HOT lane at the start of the facility or at …

Comparing Mode Shares For Non-Residential Destinations In Urban And Suburban Environments, Tasnia Subrin 2015 Portland State University

Comparing Mode Shares For Non-Residential Destinations In Urban And Suburban Environments, Tasnia Subrin

Civil and Environmental Engineering Master's Project Reports

To ensure facility for multimodal transportation is one of the most important concerns in today's transportation sector, with initiatives being taken to make multimodal transportation popular. The built environment variables have a strong relationship with transportation mode choice, but whether that relationship holds true in urban and suburban neighborhoods in the same manner has not been considered. Using data for three non-residential land uses, this research explores whether the built environment variables in suburban areas influences mode share like it does in urban areas. We used survey data conducted at the establishments regarding respondents' travel characteristics from a previous study, …

Adjusting Ite’S Trip Generation Handbook For Urban Context, Kelly J. Clifton, Kristina Marie Currans, Christopher D. Muhs

Civil and Environmental Engineering Faculty Publications and Presentations

This study examines the ways in which urban context affects vehicle trip generation rates across three land uses. An intercept travel survey was administered at 78 establishments (high-turnover restaurants, convenience markets, and drinking places) in the Portland, Oregon, region during 2011. This approach was developed to adjust the Institute of Transportation Engineers (ITE) Trip Generation Handbook vehicle trip rates based on built environment characteristics where the establishments were located. A number of policy-relevant built environment measures were used to estimate a set of nine models predicting an adjustment to ITE trip rates. Each model was estimated as a single measure: …

Commuter rail transit (CRT) is a form of rail passenger service connecting downtowns and other major activity centers with suburban commuter towns and beyond. Between 1834 and 1973, only three public CRT systems were built in the U.S. serving New York, Chicago and then Boston. There are now 25 such systems. Modern CRT systems aim to expand economic development in metropolitan areas. But do they? This paper evaluates the economic development performance of five modern CRT systems. The authors find that several economic sectors perform well within 0.50 miles of CRT stations. The authors offer planning and policy implications.

Literature suggests that rail transit improvements should be associated with more jobs and perhaps increasing share of jobs in a metropolitan area. Literature and some research also suggest that such improvements should increase the number of lower-wage jobs accessible to transit. In this paper, we assess both in the context of all 11 light rail transit systems built in metropolitan areas of fewer than eight million residents in the nation since 1981. Using census block-level job data over the period 2002 to 2011, we evaluate change in jobs and change in metropolitan area job share for all jobs, and lower- …

This workshop discussed various aspect of the mathematical part of survey methodology, as well as archiving and confidentiality issues aimed at improving data quality and its use through time. Participants identified ways to correct or minimize bias by dealing with incomplete sampling frames, using weighing and imputing procedures. We discussed methods to archive and share GPS-based survey data to preserve anonymity. Finally, we debated research needs on these topics for the next following years.


Retail Rent With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing 2015 University of Utah

Retail Rent With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

A growing body of recent research is challenging the assumptions underlying the half-mile-circle in planning for development around transit stations. In this article we review this literature and extend it to include retail land uses. We estimate the rent premium conferred on retail properties in metropolitan Dallas and metropolitan Denver, both of which have extensive light rail transit systems. We find that consistent with half-mile-circle assumptions, retail rent premiums extend only to about 0.30 mile from transit stations with half the premium dissipating after a few hundred feet and three quarters within the first 0.10 mile. We offer implications for …


Comparing Two Common Approaches To Public Transit Service Equity Evaluation, Alex Karner, Aaron Golub 2015 University of Texas at Austin

Comparing Two Common Approaches To Public Transit Service Equity Evaluation, Alex Karner, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

Understanding the equity effects of transit service changes requires good information about the demographics of transit ridership. Both on-board survey data and census data can be used to estimate equity effects, though there is no clear reason these two sources will result in the same finding of impact. Guidance from the Federal Transit Administration (FTA) recommends using either of these data sources to estimate equity impacts. This article makes a direct comparison of the two methods for the public transit system in the Phoenix, Arizona metropolitan area. The results indicate that, although both sources are acceptable for FTA compliance, the …


Stability Of Transportation Networks Under Adaptive Routing Policies, Sebastien BOYER, Sebastien BLANDIN, Laura WYNTER 2015 Singapore Management University

Stability Of Transportation Networks Under Adaptive Routing Policies, Sebastien Boyer, Sebastien Blandin, Laura Wynter

Research Collection School Of Computing and Information Systems

Growing concerns regarding urban congestion, and the recent explosion of mobile devices able to provide real-time information to traffic users have motivated increasing reliance on real-time route guidance for the online management of traffic networks. However, while the theory of traffic equilibria is very well-known, much fewer results exist on the stability of such equilibria, especially in the context of adaptive routing policy. In this work, we consider the problem of characterizing the stability properties of traffic equilibria in the context of online adaptive route choice induced by GPS-based decision making. We first extend the recent framework of “Markovian Traffic …


The Slow Mo' Main Street Concept Plan, Brandi Campbell, Amanda Davidowitz, Neil Heller, Liz Kaster, Matt Lee, Kathy Wilson 2015 Portland State University

The Slow Mo' Main Street Concept Plan, Brandi Campbell, Amanda Davidowitz, Neil Heller, Liz Kaster, Matt Lee, Kathy Wilson

Master of Urban and Regional Planning Workshop Projects

Mosier is a community located in the scenic Columbia River Gorge that is "small enough to make a difference." Mosier prides itself on its historic roots, progressive community, its role as a gateway to the agricultural valleys of Eastern Oregon. Unfortunately, Mosier's Main Street, Historic Highway 30, does not reflect the community's commitment to sustainability, economic development, and multimodal transportation. The Slow Mo' Main Street Concept Plan is a high-level guide for future transportation planning along highway 30 in downtown Mosier. The plan outlines conceptual design strategies and programmatic recommendations for Highway 30, to help ensure that Mosier's Main Street …


A Level-Of-Service Model For Protected Bike Lanes, Nick Foster, Christopher Monsere, Jennifer Dill, Kelly Clifton 2015 Portland State University

A Level-Of-Service Model For Protected Bike Lanes, Nick Foster, Christopher Monsere, Jennifer Dill, Kelly Clifton

Civil and Environmental Engineering Faculty Publications and Presentations

Several methods exist for quantifying the quality of service provided by a roadway from a bicyclist’s perspective; however, many of these models do not consider physically protected bike lanes and, of those that do, none is based on empirical data from the US. This is problematic as engineers, planners, and elected officials are increasingly looking to objective performance measures to help guide transportation project design and funding prioritization decisions. This paper addresses this gap by presenting a cumulative logistic model to predict user comfort on protected bike lanes developed from data collected during in-person video surveys. The surveys were conducted …

Economic And Traffic Impacts Following The Installation Of New Bicycle Facilities: A Denver Case Study, Stephen Antonio Rijo

Electronic Theses and Dissertations

America is currently experiencing a unique departure from the historical vehicle miles traveled (VMT) trend, often referred to as "peak travel." Decreasing VMT numbers suggest that the US is currently experiencing an unprecedented change in the way individuals utilize transportation systems. The following research calls on a need to understand the importance of improving alternative transportation infrastructure, namely cycling facilities, and how this impacts local businesses and their communities. This research informs the overarching question, "What are the economic and traffic impacts of cycling facilities?" A mixed methods analysis of retail sales tax, traffic count, and RTD transit access data …
