Databases for Assessment of Operational Tests and Traffic Models

This study involved defining data required for the validation and verification of traffic models. This study included the collection and storage of traffic data from different sites strategically selected around the country and the subsequent maintenance of the databases. Additionally, issues were addressed including type of storage needed (central vs. distributed), hardware and software platforms, and user interfaces (pre - and post-processing activities). Some of these data were obtained from existing data sources or on-going ITS field operational tests. Special emphasis was placed on data collection from the field testing of Adaptive Control Systems. The verification and validation techniques and database management system was applied to FHWA's TRAF family of models. The development of the Traffic Software Integrated System version 5.0 was completed and technical support for the ATMS R&D programs was provided.
