About the research


The objective of this project is to evaluate the reliability and accuracy of the Nebraska Department of Roads' (NDORs') probe data stream against fixed infrastructure-mounted sensor data. Based on a critical evaluation of the INRIX stream, the study will highlight key considerations for incorporating the probe data into traffic operations, planning, and management activities.

The scope of the study will be limited to selected freeways and arterial corridors. The accuracy of the data stream will be evaluated under different factors such as roadway type, average vehicle speed or volume, percentage of truck traffic, road segment length, and probe penetration.
