Improve Congestion Performance Measures Via Conflating Private and Public Information Sources

Many state transportation agencies and research institutions are investing heavily to establish a Congestion Performance Management System (CPMS), which is mandated by the federal legislation, Moving Ahead for Progress in the 21st Century Act (MAP 21, PL 112-141), and reaffirmed by the newly enacted Fix America Surface Transportation Act (FAST ACT 2015). The main elements of Congestion Performance Measures, such as travel time and speed, traffic volume, and length of roadway segments are usually not collected by a single entity, public or private. There is no systematic data collection on all the roadway systems, and the collection of certain data by each agency may be sporadic and/or targeted to certain projects.

This research will explore the potential conflation of Roadway Characteristics Inventory (RCI) collected by public agencies and other just-in-time travel information such as speed and real time congestion status, often collected by private vendors, on various transportation networks.
