Wide-area, web-based mobility analysis using probe data

This paper describes a web-based visual analytics monitoring system for identifying major bottlenecks, reporting on travel time reliability, and displaying other congestion measures using private sector vehicle probe data fused with agency incident/event data where available. This system represents an exponential leap forward in capabilities to report on system performance in terms of speed and ease of access, usability, and overall data availability. This paper demonstrates how states are using the system to justify construction projects, demonstrate the benefits of transportation projects, identify areas for improvement, and analyze travel times using a variety of data sources, with an emphasis on vehicle probe data. The underlying system includes probe data from as early as 2008 through today that is being used to analyze trends from year-to-year, month-to-month, and day-to-day. The resulting suite of tools provide significant new capabilities to researchers and analysts that will likely fuel additional research.
