Webinar: Visual Exploration of Trajectory Data
 

PRESENTATION ARCHIVE

OVERVIEW

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures. Second, Dr. Franz (CATT Lab) will demonstrate a suite of visual analytics that enables transportation agencies to easily explore terabytes of GPS trajectory data. He will demonstrate different tools and share the experience of 5 state DOTs that are currently using CATT Lab's trajectory data suite.

KEY LEARNING OUTCOMES

  • Trajectory data represents the most complete vehicle-probe data and provides unprecedented opportunity for transportation system analysis.
  • Transportation agencies can easily leverage visual analytics to obtain insights in statewide traffic patterns and...

PRESENTATION ARCHIVE

Small towns and cities outside of national parks and other major natural amenities throughout the western United States are becoming increasingly popular places to visit and live. As a result, many of these gateway and natural amenity region (GNAR) communities—including places such as Jackson, Wyoming, and Moab, Utah—are facing a variety of “big city” issues, such as severe congestion, lack of affordable workforce housing, and concerns about sprawl and density. This webinar will introduce the planning and transportation concerns being experienced by GNAR communities throughout the west. It will then share the tools and resources developed by the University of Utah to train planners to work in these unique communities and to help these communities enhance livability and sustainable transportation options. The webinar will also introduce the University of Utah’s new Gateway and Natural Amenity Region Initiative and ongoing research aimed at better understanding and addressing the planning and transportation issues in GNAR communities.

OVERVIEW

Multimodal transportation systems (e.g., walking, cycling, automobile, public transit, etc.) are effective in increasing people’s travel flexibility, reducing congestion, and improving safety.  Therefore, it is critical to understand what factors would affect people’s mode choices. With advanced technology, such as connected and automated vehicles, cities are now facing a transition from traditional urban planning to developing smart cities. To support multimodal transportation management, this study serves as a bridge to connect speed management strategies of conventional corridors to connected vehicle corridors.

The study consists of three main components. In the first component, the impact of speed management strategies along traditional corridors was evaluated. In the second component, the impacts of the specific speed management strategies, signal retiming and...

OVERVIEW

Small towns and cities near national parks, public lands, and other natural amenities across the West are experiencing rapid growth and increased tourism. As we have documented via our prior NITC-funded research, this has created a range of big city challenges for these “gateway communities,” particularly in the form of interconnected transportation, land use, and housing issues. Seeking to help gateway communities better prepare for and respond to their transportation and planning challenges, the Gateway and Natural Amenity Region (GNAR) Initiative team translated the findings from our research on planning and development challenges in gateway communities into an online learning program.

This program, the "GNAR Academy Fundamentals: Foundations for Planning and Collaboration in Gateway Communities and Regions" includes seven modules, each of which...
