Summary: The Federal Transit Administration invests in building the capacity and improving the quality of public transportation throughout the United States of America. Under FTA's leadership, public rail, bus, trolley, ferry, and other transit services have reached greater levels of safety, reliability, availability, and accessibility. Come hear the highlights of FTA's impacts and participate in an interactive question/answer session and discussion on career options in public transportation!

Summary: Dr. Lovell will talk about three projects funded by NASA and the FAA, addressing congestion in the National Airspace System. Dr. Lovell's team developed diffusion-based queuing models of individual airports that could support better building blocks for network-wide congestion models. The advantage of the new models is their flexibility with respect to input distributions. In a study for the FAA, Dr. Lovell's team developed day-of-operations collaboration "languages" suitable for the FAA and individual carriers in order to collectively manage expected airspace disruptions. Finally, he will discuss a study on predictability in the airspace, with a focus on scheduled block times.
Dr. Lovell is an Associate Professor with joint appointments in the Department of Civil and Environmental Engineering and the Institute for Systems Research. He is a member of the faculty of the Applied Mathematics, Statistics, and Scientific Computation Program. He is director of the University of Maryland chapter of Engineers Without Borders - USA, and serves that organization on its board and as a leader of one of its Technical Advisory Councils. Dr. Lovell received his B.A. in Mathematics from Portland State University in 1990, and M.S. and Ph.D....

Abstract: Despite the never-ending cascade of depressing economic developments recently, there are some encouraging new trends to be discovered. Some of these trends relate to the vehicles we buy and how we drive them, and the consequences of these actions. In this presentation, I will discuss several new findings about the positive influences of the recent economic changes on (1) the fuel efficiency of purchased new vehicles, (2) the amount and type of driving that we do, (3) how much carbon dioxide emissions we produce from driving, and (4) the number of road fatalities.
Bio: Dr. Michael Sivak is a Research Professor and the Head of the Human Factors Division of the University of Michigan Transportation Research Institute (UMTRI). He received his Ph.D. in Experimental Psychology from the University of Michigan. Dr. Sivak's primary expertise is in perceptual and cognitive aspects of driving. Examples of his recent research topics include human-factors aspects of vehicle design, bounded rationality and driver behavior, and the relative risks of flying and driving. In 2001, he was named a Distinguished Research Scientist by the University of Michigan. In 2006, he received the A.R. Lauer Award from the Human Factors and Ergonomics Society for outstanding contributions to human aspects of the broad area of safety.

Summary: Signalized intersections often rely on vehicle detection to determine when to give a green light. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) includes an on-pavement marking and curbside sign that public agencies can use to indicate where cyclists should position themselves while waiting at an intersection. This presentation reviews the effectiveness of current markings, signs, and other methods used to help cyclists properly position themselves over detection.
Stefan Bussey is an undergraduate civil engineering student at Portland State University. He is interested in exploring how road users’ interactions with each other and the built environment affect the efficiency and safety of road networks. He currently works as a civil design intern at Harper Houf Peterson Righellis Inc.

Abstract: This seminar will describe the results of a recent study for the Australian National Road Authority (Austroads) which reviewed emerging types of private vehicles, including everything from Segways and mobility scooters to three wheel cars and micro/mini cars, and their implications for road system management.The emergence of some of those vehicle types presents real challenges from the perspective of safely managing their integration into the road system even though they present some real opportunities from the perspective of improving the sustainability of the transport system. Although the analysis is largely from an Australian perspective, some of the general insights which came from the study are transferable and one of the key recommendations (regarding moving towards more performance based than prescriptive based standards for vehicles) has potential international application.
