To raise the visibility and awareness of PacTrans sponsored research at all participating campuses.
One presenter from each poster will have 60 seconds at the podium to provide an innovative introduction to their poster. The moderator will time each presenter and will end each presentation promptly at 60 seconds. Technical summary descriptions of the research are strongly discouraged, however, poems, dance, skits, humor, and any novel approach is highly encouraged. The intention of these brief presentations is to spark interest in conference participants so that they will wander by your poster during the remainder of the hybrid poster session.
Date and Time
During the PacTrans Regional Transportation Conference on October 16, 2015 from 10:00 a.m. to 10:45 a.m.
Title of poster, list of co-authors, and a maximum 250 word abstract submitted via email to Maria Bayya, email@example.com.
Sep 11, 2015 by 5 p.m. PST.

The Effect of Government Policy on the Promotion of Energy Efficient Vehicles
A wide range of government policies have been implemented around the world to increase demand for energy efficient vehicles (EEVs) including cash rebates, reduced sales taxes, registration fee waivers, and toll road exemptions. Despite these efforts, the available literature analyzing the effects of these incentive policies on EEV demand is quite limited. Further complicating matter is that EEV marketplaces are dynamic, and sales prices of EEVs may fluctuate in response to government incentives, since increase demand can influence market forces to in turn increase EEV prices. A comprehensive analysis that examines the influence of EEV policies on market demand, therefore, must account for possible endogeneity between market demand and sales prices. In this presentation, I examine and estimate the effects of different types of government incentives on both EEV demand (market and fleet penetration), and EEV price premiums across 15 metropolitan regions from 2008 to 2012. Using error components three stage least squares, I dis-entangle the endogeneity between EEV demand and price, and quantify the effects of a variety of additional factors that influence both price and demand including inflation rates, population density, and fuel costs. Up-front one-time subsidies such as cash rebates increase EEV market penetration by 1.4% and fleet penetration by 0.3%, however, unlike other types of incentives, also lead to 11.3% higher price premiums.
Dr. Simon Washington Professor Washington holds the ASTRA Chair at the Queensland University of Technology in Brisbane, Australia. He contributes to the fields of behavioural econometrics in transport safety and risk analysis, urban planning, evaluation, and travel behaviour. He is Associate Editor of two leading international transport journals (Journal of Sustainable Transport; and the J of Anal Meth in Acc Res), Editorial Board Member of four leading international journals (Acc Anal & Prev,Trans Res A and C, and the J Trans& Stat). He has authored or co-authored over 100 peer-reviewed journal articles and conference proceedings, a 2ndedition of a textbook adopted in over 20 countries (1000+ citations), and 6 book chapters. His work has been cited by more than 4000 other transport researchers. He has been lead CI on $28 Million on externally supported research and has secured nationally competitive Australian research grants from the Australian Research Council, the National Health and Medical Research Council, and Cooperative Research Centres programs, and in the US including the US National Academy of Sciences, the National Highway Traffic and Safety Administration (US), and the Federal Highway Administration (US). Prior to joining QUT he served on the faculties of UC Berkeley, Arizona State University, the University of Arizona, and the Georgia Institute of Technology.

James Amundsen, recent Washington State University BS in Civil Engineering graduate, received the 2015 Dwight David Eisenhower Graduate Fellowship. The Dwight David Eisenhower Transportation Fellowship Program competitively awards fellowships to students who are pursuing transportation-related degrees, and attracts the brightest minds to the field of transportation and research while advancing workforce development.
Amundsen will begin his graduate studies at WSU this semester and will perform a research assistantship under Dr. Haifang Wen, focusing on the evaluation of the effects of recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) on the fatigue performance of hot-mix and warm-mix asphalt.

The ITS America Symposium on Building a Smart, Diverse, and Shared Travel Network, held July 16 – 17 at the University of Washington, brought transportation professionals from both public and private sectors together to discuss shared-use mobility and technology-driven solutions. The symposium featured a variety of panels and speakers, and keynote addresses were delivered by Regina Hopper, President and CEO, ITS America, Scott Kubly, Director, Seattle Department of Transportation, and the Hon. Secretary Lynn Peterson, Washington State Department of Transportation. Dr. Yinhai Wang, PacTrans Director, provided closing remarks and described the center’s work and research.
PacTrans, a sponsor of the event, provided a technical tour of the STAR Lab to symposium participants. Attendees learned about the lab’s work supporting advanced ITS research, cultivating ITS professionals, exploring effective solutions to transportation problems, and constructing a bridge between the UW and agencies of transportation practice. Specific research work demonstrated included UAV-based traffic data collection, Media Access Control (MAC) address sensing for multi-modal data collection, Microsoft Kinect-based pedestrian detection, and the Digital Roadway Interactive Visualization and Evaluation Network (DRIVE Net).

The effectiveness of a traffic sign is collectively influenced by the sign’s understandability, legibility distance, glance legibility, and learnability; however, understandability has been repeatedly identified as a one of the most important measures of effectiveness. This study compared a variety of online survey questions and driving simulation tasks to assess the understandability of alternative Tourist Information signs in Oregon. In all of these tests, the “INFO” Sign was shown to be the most understandable of the alternatives evaluated in this study by a significant margin. The two “i” Sign alternatives had the second and third highest comprehension rates for driving simulator subjects. However, it is likely that comprehension rates for the “i” Sign will continue to increase in the future due to its prolific usage in a wide variety of contexts.
The results were accepted for publication in the ASCE Journal of Transportation Engineering. Separately, the results of the study will be presented at the 15th Annual COTA Conference in Beijing, China by Dr. David Hurwitz. The PIs and PacTrans would like to recognize the cash-match provided by Travel Oregon, without which the project would not have been nearly as successful.
