Standard Specification for Archiving ITS-Generated Traffic Monitoring Data
1.1 This specification describes data elements and schema for an archived data management system for intelligent transportation system (ITS)-generated traffic monitoring data, including conventional traffic monitoring data, data collected directly from ITS systems, and travel-time data from probe vehicles. It establishes the names of the data elements, their interrelationships, and their procedural definitions. These procedural definitions include data collection instrumentation and methodology as well as recommended procedures for calculating traffic statistics.
1.2 This specification is intended for primary use by archived data management system (ADMS) developers and administrators. It also can be used by traffic operations and planning stakeholders who need to understand the contents of the ADMS. ITS systems exist across a variety of governmental levels, and the data archived in such a system would be available to all levels of government and the private sector, making this specification applicable to all levels of government and the private sector.
1.3 Many users might wish to develop integrated archived traffic data management systems that include both ITS-generated data and data collected from conventional traffic-monitoring programs. The latter use requires a superset of data elements to meet the articulated nature of a conventional traffic-monitoring program. This specification will describe a basic set of data elements applicable to ITS-generated traffic data and the additional data elements required for conventional traffic-monitoring programs. In the following discussion, the specification for the system for ITS-generated data will be referred to as the “basic system,” and the one for ITS plus conventional traffic-monitoring data will be denoted the “extended system.” Travel-time data from probe vehicles are stored in separate tables that can be linked through the roadway link identifiers.
1.4 This specification is applicable to traffic data collected by ITS and stored in an ADMS. Similarly, this specification also can be used with other types of historical and monitored traffic data collected and stored in an ADMS, including travel-time data from probe vehicles.
