Kara Luckey was awarded "Best Poster" at the U.S. Department of Transportation Dwight D. Eisenhower Fellows Showcase held at the 93rd Annual Transportation Research Board meeting in D.C. Kara was invited to present in the showcase as part of her 2013-14 Eisenhower Fellowship, which supports top graduate students in transportation. Kara's poster, "Promoting socially-equitable transit and transit-oriented development: What are the key planning and policy levers?," provides an overview of her dissertation work, which is currently underway. This research focuses on identifying the ways in which cities and regions are maximizing the benefit of regional rail transit for low- and moderate-income families through planning and policies, and assessing the effectiveness of those interventions. Her work complements existing case studies by undertaking a systematic cross-case comparison of 20+ U.S. metropolitan areas. Kara's poster can be downloaded here.
Kara Luckey presents at TRB: "Understanding the level of integration of light rail into communities in the Denver region"
Kara Luckey presented work she co-authored with Dr. Marshall on measuring the 'level of integration' between transit stations and the fabric of the community at the 93rd Annual Transportation Research Board in Washington, D.C in a session focused on "Light Rail: International and National Perspectives" sponsored by the Light Rail Transit Committee (APO75) The concept of 'Level of integration' accounts for three components: built environment factors, transit service characteristics, and accessibility to amenities. The work presented at TRB explores how different components of integration relate to four travel outcomes among station-area residents in Denver, Colorado. Kara and Dr. Marshall's paper can be downloaded here.
ACT member Rachael Bronson presented the preliminary steps of her transportation resiliency research at the Bicycle Urbanism Symposium in Seattle, WA. The goal of this portion of her research is to build the foundation of a transportation resiliency assessment by measuring the quality and quantity of two mode choice options—bicycling and walking—in Denver, CO. Using a Geographic Information System (GIS), all Denver streets where bicycling and walking is permitted are measured by bicyclist/pedestrian tolerance of traffic stress. This tolerance is classified into four levels of traffic stress (LTS) 1-4. The results of the GIS analysis suggest that although the availability of multi-modal transportation facilities of various stress levels are present throughout the city, these facilities lack the connectivity necessary to make the network accessible to individuals of lower stress tolerance. This methodology offers a way to measure the quantity and quality of bike/ped mode options, which will inform the second part of her research, the resiliency assessment.
In the resiliency assessment, various variables (including the LTS levels) will be factored into a multinomial logistic regression mode choice model to determine the percentage of the population that will switch to a different transportation mode under various disruptive event scenarios. The cost savings of the mode shift will be measured to assess the change in transportation costs for neighborhoods/households.
Rachael was able to complete this work with the support of her advisor, Dr. Wesley Marshall ( This study was made possible thanks to data from the City and County of Denver. Funding for this work is provided by the Mountain-Plains Consortium, a program sponsored by the U.S. Department of Transportation.
ACT members Dan Piatkowski and Rachael Bronson presented a poster evaluating the Denver Regional Bike to Work Day event at the Bicycle Urbanism Symposium in Seattle, WA last week. The poster was completed with the support of ACT faculty Director Dr. Kevin Krizek and Co-Director Dr. Wes Marshall.
The goal of the research was to understand the impact of Bike to Work Day (BTWD), and to analyze whether this motivation and impact is different for different types of cyclists. This research used data from a survey of participants in the 2012 Bike to Work Day event in Denver, Colorado. The survey was administered online by the Denver Regional Council of Governments (DRCOG). In total, 1,018 surveys were completed, a 32 percent response rate. BTWD participants were classified into four groups (year-round commuter, frequent commuter, occasional commuter, and only on BTWD commuter) based upon response to question: Please take a moment to think about how often you bicycle to work, and then choose the category that best describes you.
Statistical analyses included ANOVA, desctiptives and t-tests, and findings include the following:
In conclusion, BTWD impacts diverse cycling populations differently, and this may be its greatest strength. It provides a supportive and fun climate for those who do not regularly cycle to try it, and sustains the behavior of those who currently bicycle to work.
Thanks to DRCOG for providing ACT Research Group the opportunity to access the survey and evaluate the impacts of BTWD. Thanks also to Drs. Marshall and Krizek for their support and guidance.
Kara Luckey’s paper entitled “Assessing the Effectiveness of Approaches to the Allocation of Low-Income Housing Tax Credits in Proximity to Rail Transit” has been accepted for lectern presentation at the Transportation Research Board 91st Annual Meeting - http://www.trb.org/AnnualMeeting2012/AM2012Program.aspx to be held in Washington, D.C. in January 2012
