Summary: Since about 2008, the planning world has been experiencing a paradigm shift that began in places like California and Oregon that have adopted legislation requiring the linking of land use and transportation plans to outcomes, specifically to the reduction of greenhouse gases (GHGs). In response to this need, Calthorpe Associates has developed a new planning tool, called UrbanFootprint, on a fully Open Source platform (i.e. Ubuntu Linux, PostGIS, PostGreSQL, etc.). As a powerful and dynamic web and mobile-enabled geo-spatial scenario creation and modeling tool with full co-benefits analysis capacity, UrbanFootprint has great utility for urban planning and research at multiple scales, from general plans, to project assessments, to regional and state-wide scenario development and analysis. Scenario outcomes measurement modules include: a powerful ‘sketch’ transportation model that produces travel and emissions impacts; a public health analysis engine that measures land use impacts on respiratory disease, obesity, and related impacts and costs; climate-sensitive building energy and water modeling; fiscal impacts analysis; and greenhouse gas and other emissions modeling.

Driver distraction accounts for up to 30 % of accidents on the roadway. One of the leading causes of driver distraction is the concurrent use of a cell phone to talk or text message. In fact, accident rates are quadrupled for drivers talking on a cell phone and increase by a factor of 8 for those drivers texting. I will show that these impairments are primarily due to limitations in attention, and as such are not eliminated with hands-free devices. Cell phones cause a form of inattention blindness, wherein drivers look but fail to see important information in the driving environment, such as a child in a crosswalk. These impairments differ qualitatively from other seemingly similar sources of distraction (e.g., listening to the radio or books on tape, talking to a passenger, etc.) and are similar to the impairments associated with driving drunk. Efforts to practice away the dual-task interference have proven unsuccessful indicating that you cannot train yourself to become an expert cell phone driver. However, there are intriguing individual differences for a very small group of "supertaskers" who can, in fact, drive and talk on a cell phone with little or no impairment. Together these data have important implications for theories of attention...

OVERVIEW
There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.
Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies, published in April 2018, is the first study to explore bicycle signal control strategies for addressing bicycle-vehicle conflicts. This study analyzed the operational impacts of traditional...

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.
