    1/31/12 - The Visual Accessibility of Indoor Spaces

    1/31/12 - The Visual Accessibility of Indoor Spaces

    Visual accessibility—how effectively vision can be used to travel safely through or complete activities within a space—has an important impact on low-vision mobility. In this seminar, Gordon Legge will describe an empirical approach for studying the visual accessibility of indoor spaces, including experiments on the detection and recognition of steps and ramps. He will also outline the development of a new form of adaptive technology—the Digital Sign System—to assist visually impaired people with indoor navigation.

    12/8/11 - Toward Universal Access to Seamless Travel of Indoor and Outdoor Spaces With and Without Vision

    12/8/11 - Toward Universal Access to Seamless Travel of Indoor and Outdoor Spaces With and Without Vision

    The consideration of vision loss is of growing importance in research, planning, and implementation of travel and transportation needs. There are approximately 12 million people with some form of visual impairment in the United States, and this number is estimated to double in the next 20 years as a consequence of our aging population. To meet the needs of this growing population, far more research is needed to better understand what information is used to support spatial behaviors for people with low (or no) vision.

    In this seminar, Nicholas Giudice will discuss some practical solutions that can improve information access, safety, and efficient travel for people with vision loss. He will also explain why the failure to consider human perceptual and cognitive factors often leads to poor design decisions—especially when incorporating auditory, haptic, and other non-visual information into traditional navigation systems and transportation networks.

    12/1/11 - Transportation Safety Issues and Priorities in Minnesota

    12/1/11 - Transportation Safety Issues and Priorities in Minnesota

    Traffic safety comes in several shapes and sizes. Ask a maintenance worker what safety is and you might hear that it's plowing roads when it snows. A transportation designer might say that safety is designing signposts that break away without intruding into a vehicle. A local official might say that installing an interchange or converting a two-lane road to four lanes is safety.

    Safety has been ingrained in the transportation profession since the time of horse and buggy trails. In this presentation, Brad Estochen will discuss the Minnesota Department of Transportation's diverse approach to roadway safety. He will highlight traditional measures and prioritization processes as well as approaches for addressing safety on a systemic level and using data to help drive Minnesota toward its goal of zero deaths.

    11/10/11 - Cyclopath: Personalized Routing and Open Collaboration for Bicyclists

    11/10/11 - Cyclopath: Personalized Routing and Open Collaboration for Bicyclists

    Cyclopath is a routing and mapping system for bicyclists in the Twin Cities metro area. The system, developed at the University of Minnesota, generates bicycling routes that can be personalized to meet individual cyclists' preferences. Cyclopath is also the world's first full-featured geographic wiki—all users can edit the system's maps of roads and trails. Much information about bike trails and cycling conditions is currently known only to individual cyclists, and Cyclopath allows them to share this key knowledge with each other.

    Cyclopath is a popular resource for the cycling community and a powerful research platform. In this seminar, Loren Terveen will describe the innovative aspects of the Cyclopath system design, summarize several research studies of Cyclopath users and usage, and describe a few new development and research directions.

    10/27/11 - Development of a Traffic Information and Dissemination System for Work-Zone Environments

    10/27/11 - Development of a Traffic Information and Dissemination System for Work-Zone Environments

    To save lives and prevent injuries on U.S. highways, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is essential. In this seminar, M. Imran Hayee reviewed the architecture, functionality, and field demonstration results of a newly developed V2I communication system that incorporates V2V assistance. The system, which relies on dedicated short-range communications technology, was developed to improve traffic efficiency and increase safety in congested work-zone areas.

    The system can automatically acquire important traffic information—such as travel time and the starting point of congestion—and relay it back to drivers approaching the work zone. It uses a single roadside unit to collect traffic data from vehicles traveling on the road that are also exchanging information with each other. Field demonstration results indicate that the system can adapt to dynamically changing work-zone traffic environments and can cover larger work-zone areas than a system using V2I communication without V2V assistance.
