Dr. Kelly Clifton was appointed to the Oregon Department of Transportation’s policy committee charged with developing the Statewide Transportation Strategy, including reductions in transportation-related greenhouse gas emissions. The committee will make recommendations for the strategy to the Oregon Transportation Commission for adoption.

“Discretionary Activity Location Choice: In Home or Out of Home?” in press

Abstract

This paper examines the location choice associated with discretionary activities (in-home versus out-of-home). These substitution patterns are important in terms of travel demand as in-home activities do not necessitate travel while out-of-home activities incur travel. Mixed logit models are

estimated using an activity dataset (2003 CHASE data) to analyze the factors associated with this choice at the individual activity-level. Results suggest that the attributes of an activity significantly contribute to understanding the likelihood of engaging in out-of-home activities. Activity type interaction terms reveal the varying influence that socio-demographics, activity attributes and travel have over four different activity types modeled. The results reveal that the location choice (in-home versus out-of-home) is sensitive to travel characteristics. As the travel time and cost increases, an individual is less likely to engage in an activity out-of-home. Compared to passive and social activities, the location of active activities is more sensitive to changes in travel attributes.

Dr. Clifton to direct the Oregon Modeling Collaborative

The Oregon Modeling Collaborative (OMC) was formed in spring 2010 to provide modeling tools and methods in support of Oregon’s transportation and land use planning and policy efforts. The OMC is comprised of members of the academic, policy and consulting sectors in Oregon and led by Dr. Kelly Clifton at PSU. This modeling initiative will enhance Oregon’s cutting-edge analytical methods and tools and a major statewide data collection program underway to meet the challenges of planning for a sustainable future. The OMC is initially funded by a grant from OTREC (http://otrec.us/) and research support from ODOT. More information about the OMC can be found at: http://www.pdx.edu/omc/.

Dr. Kelly Clifton awarded two OTREC research projects in 2010

Dr. Clifton was awarded two new research grants as part of the 2010-2011 OTREC grant cycle. The project “Contextual Influences on Trip Generation” partners with Metro and surrounding communities to examine trip rates for land development across a variety of urban conditions. In partnership with the Portland Development Commission, City of Portland, Travel Oregon and Bikes Belong, the “Economic Impacts of Cycling” will look at the travel and consumer behavior of cyclists and other patrons in commercial centers with varying bicycle infrastructure.

Stimulous Spending in Maryland on WYPR’s Maryland Morning

admin — Fri, 14 Aug 2009 16:55:00 +0000

Kelly Clifton on WYPR’s Maryland Morning. The American Recovery and Reinvestment Act–better known as the stimulus bill–turns 6 months old on Monday. Nationally so far, $73billion out of nearly $581 billion has been spent, according to the public interest news site Pro Publica (there’s an additional $212 billion in estimated tax cuts). Some analysts contend the stimulus spending is part of why the recession seems to be ending; others say that’s far from clear. Maryland is slated to receive about $4 billion all told, and we want to see how the state has been spending it. We’re joined by Kelly Clifton, an associate professor of Urban Studies and Planning at the University of Maryland at College Park; and Neil Bergsman, director of the Maryland Budget and Tax Policy Institute.

Upcoming Talk at the Carolina Transportation Program – March 16, 2009

admin — Sat, 14 Mar 2009 22:24:03 +0000

Professor Kelly Clifton from the National Center for Smart Growth at the University of Maryland will give a talk entitled “Activity and Travel Choice Models – Extensions for Evaluating Energy Consumption.” Details included below.

Time: March 16, 2009 at 12:30 pm

Location: New East Building, Room 102 on the campus of UNC-Chapel Hill

Directions: Visit
http://www.planning.unc.edu/index.php?option=com_content&view=article&id=75&Itemid=23
for directions to New East.

This talk focuses on some recent research into activity and transportation choice models and the potential extension of these models to understand of household energy consumption to meet residential and transportation needs. The first part of the talk examines the decision to engage in an activity in the home or outside of the home using an individual-level, binary choice model that estimates the choice of activity location as a function of personal characteristics, activity attributes and the land use and transportation system characteristics. Many models of human activity only focus on out-of-home activities because the travel incurred to reach the activity is the primary interest. However, it is important to consider the full complement of daily activities and their location in order to understand the phenomena influencing these choices and the potential for substitution. The second
part of the talk will discuss how these models and results might fit into a larger framework to understand the direct energy consumption patterns of households and implications for policy.
