As intelligent transportation system (ITS) applications continue to be deployed in Texas, large quantities of data are becoming available from ITS sensor and detector systems. Traffic management centers collect the data, which typically include traffic conditions, incident/accident data, ITS control responses, and other roadway or environmental characteristics, for use in real-time by TxDOT and partner agencies to manage the transportation system. When these data are archived, they can be used for numerous transportation analyses, such as estimation of ITS benefits, computer model calibration, congestion monitoring, transportation planning, or even pavement design. However, little guidance currently exists for data archiving. The objective of this research project was to assemble guidance that could help TxDOT in further developing data archiving systems across the state. This guidance includes information on: basic principles of data archiving; determining what data and how much to archive; performing quality control to ensure data meets certain quality requirements; and developing a data archiving system using the National ITS Architecture and relevant standards.
