    Developing Driving Support Systems to Mitigate Behavioral Risk Patterns Among Teen Drivers
    (University of Minnesota Center for Transportation Studies, 2007-08) Brovold, Shawn; Ward, Nic; Donath, Max; Simon, Stephen
    Based on statistics from the Centers for Disease Control and Prevention (2003), motor vehicle deaths are the leading cause of teenage fatalities. A possible approach to mitigate the incidence of teenage driver crashes and fatalities is through the use of in-vehicle technology. The design and development of a first-generation prototype Teen Driver Support System (TDSS) to explore the feasibility and opportunities of such technology has been completed. The TDSS system includes technology designed to address several primary contributing factors associated with the majority of teen fatal crashes: speeding, seatbelt use, driver inexperience, and alcohol use. This has been implemented using a combination of what researchers call forcing, feedback, and/or reporting functions. Forcing functions take the form of ignition interlocks to enforce seat belt compliance and sober driving. A feedback function provides real-time tutoring and warnings about illegal or unsafe speeds through auditory warnings. A reporting function records vehicle information for parents to review and supervise (and enforce) teen driver performance. A speed feedback and reporting component is used for driver compliance with safe travel speeds. The system correlates the location (using GPS) of the vehicle to a digital road map and the road's corresponding speed limit. A weather-based speed element incorporates current weather information that is used to warn a driver if the vehicle's speed is too high for current weather conditions. Similarly, speed warnings specific to curves are included to warn if speed is excessive for the prevailing geometry. With the prototype TDSS, the researchers developed a method of integrating a seat belt interlock that requires the driver's seat belt to be engaged before the vehicle will start. Seat belt use is continuously monitored during each trip, and lack of seat belt use is recorded for later review. An additional interlock for alcohol is reserved for teen drivers with preexisting alcohol-related convictions. Since alcohol interlock systems are commercially available, they can be demonstrated as an optional component of the TDSS. In anticipation of potential future applications, such as the enforcement of certain graduated driver licensing (GDL) requirements, the system includes a biometric fingerprint component, which uses a fingerprint sensor to identify the driver and parent so that the system can log the number of training hours spent behind the wheel.

    ITS Personal Data Needs: How Much Do We Really Need to Know?
    (Intelligent Transportation Systems Institute, Center for Transportation Studies, University of Minnesota, 2012-07) Douma, Frank; Garry, Thomas; Simon, Stephen
    The recent spread of geolocation technology in intelligent transportation systems (ITS) raises difficult and important policy questions about locational privacy. However, much of the current public discussion on locational privacy and ITS appears at risk of becoming increasingly disconnected. In one camp are privacy advocates and others who oppose the spread of ITS locational technology on privacy grounds. In the other camp are technologists and the ITS industry who generally view privacy issues as a secondary matter. The net result is that the ITS privacy debate often involves two sides talking past each other, with too little energy spent on finding potential common ground. This disconnect in part results from a lack of basic clarity, on both sides, about just what the needs and interests of those involved in the ITS privacy issue are and how they relate to the betterment of the transportation system. This report sheds new light on the ITS privacy debate by identifying just who is involved in the ITS privacy problem and what their goals are with respect to privacy and ITS data. The analysis identifies the types of locational data and the methods for obtaining it that create privacy conflicts and, in turn, recommends general approaches for both policymakers and industry practitioners to better manage these conflicts. The report represents a first effort in mapping the interests of participants in the ITS privacy debate.
