This report assesses the potential for probe data to support work zone performance measurement programs. It includes an overview of probe data and the advantages and disadvantages of probe data sources relative to traditional fixed sensors. It identifies when and how probe data sources can be used to support work zone performance measures. It also characterizes the applicability of different types of probe data to help manage different types of work zones.
The report then exemplifies this information by presenting summaries of projects that made use of probe data for work zone performance measures or examined the capabilities and limitations of probe vehicle data. A particular focus was on a recent Maryland State Highway Administration project that provided a comprehensive example of the use of probe data sources to compute the performance measures by developing a web-based work zone performance measure application.
