D-STOP Researchers Called On to Present throughout World and Internet
Humphreys Testified before U.S. Congress on UAV Threats
D-STOP researcher Todd Humphreys, an expert on unmanned aerial vehicle (UAV) security, testified before U.S. Congress on March 18, 2015. He was called to testify before the Subcommittee on Oversight and Management Efficiency on “Unmanned Aerial System Threats: Exploring Security Implications and Mitigation Technologies.” Other speakers appearing at the hearing included Major General Frederick Roggero, USAF (ret), President and Chief Executive Officer of Resilient Solutions, Ltd.; Chief Richard Beary, President of the International Association of Chiefs of Police; and Dr. Gregory S. McNeal, Associate Professor at the Pepperdine University School of Law. In announcing the hearing, Subcommittee Chairman Scott Perry, R-Pa., issued this statement of purpose for the day’s events: “The proliferation of small unmanned aerial systems in the U.S. is coming. But are we ready to deal with the threats that could come with this emerging technology? Recent incidents like the quadcopter that crashed at the White House and drones flying over Paris landmarks raise concerns. Our hearing will examine the security issues associated with opening American airspace to drones and possible solutions for homeland security and law enforcement to deal with any challenges.” Watch the testimony.
Heath Featured on RCR Wireless’ HetNet Happenings
D-STOP researcher Robert Heath discussed his research in MIMO and Millimeter Wave with RCR Wireless News‘ Managing Editor Sean Kenney. On HetNet Happenings (an online show that covers distributed antenna systems, small cell, Wi-Fi, and other related topics), Kenney interviewed Heath about how these technologies could shape the future 5G cellular standard.

Bhat Collaborated with Cambridge Systematics on TMIP Webinar
Along with Thomas Rossi of Cambridge Systematics, D-STOP Director Chandra Bhat conducted a webinar titled “Transferability: How to Make It Work Best for Your Model.” This national-level webinar, which took place in February 2015, was conducted through the FHWA’s Travel Model Improvement Program (TMIP). The focus of the webinar was on specific ways in which modelers can choose the best methods and practices for transferring model parameters given the types of models and data available. Planners in many cases may have superior alternatives to the use of national average parameters, especially when some local data are available. Transferability results may be improved through use of small amounts of local data in an updating process when transferring models. This webinar sought to present that knowledge to provide planners along with practical guidance in determining the best transfer methods for their unique situations. The guidance included variable specification, model updating procedures using some local data, procedures to use when local data are unavailable, and use of data from national sources. Simple examples of the various model transfer methods were presented. Download a PDF of the webinar presentation.
Duthie Presented D-STOP Projects at UTC Safety Summit
In March 2015, D-STOP researcher Jen Duthie attended A Summit of University Transportation Centers for Safety, an event hosted by the Technologies for Safe and Efficient Transportation Center (a collaboration between Carnegie Mellon University and the University of Pennsylvania) and held in Pittsburgh. Duthie presented D-STOP’s current slate of safety-related projects—clearly a topic of near-universal significance, as the event involved 14 UTCs, representing over 50 universities in all. In addition to researcher presentations, panel participants included representatives from the American Automobile Association (AAA), the American Society of Civil Engineers, the American Trucking Association, the Insurance Institute for Highway Safety, the Intelligent Transportation Society of America, the League of American Bicyclists, and the Transportation Research Board. USDOT Assistant Secretary Greg Winfree gave the keynote speech. D-STOP projects related to safety include High-precision GPS Vehicle Tracking to Improve Safety; Infrastructure-Informed Travel Sheds; and The Formulation and Estimation of a Spatial Skew-Normal Generalized Ordered-Response Model (see full list of current D-STOP projects).

Bhat Invited to Present in Australia
Last fall’s 10th International Conference on Transport Survey Methods, held in Leura, Australia, featured D-STOP Director Chandra Bhat’s expertise in the data collection field. Dr. Bhat participated in an informal clinic on high dimensional heterogeneous choice data and co-chaired a workshop titled “Conducting Travel Surveys Using Portable Devices: Technological Challenges.” This workshop examined the range of portable devices, their advantages and limitations in terms of technology, the methodologies to extract useful information for travel behavior analysis from portable device data, and how data from multiple sources may be fused together to obtain the data needed for travel demand modeling. This workshop was designed to explore the modern technologies that are playing an increasing role in our lives, as there is an opportunity to harness such technologies for travel demand modeling and travel behavior analysis.
