Physical Object: ITS Roadway Equipment
Roadway ATSPM Data Collection
Overview
'Roadway ATSPM Data Collection' collects signal controller and cabinet events with a high degree of granularity of up to 10 times every second. It stores the collected data and, per the configuration settings, uploads it to the server (on-premises or cloud hosted) hosting the Automated Traffic Signal Performance Measures (ATSPM) software for data analytics and processing to generate signal performance measures. Data collected includes data concerning the high-resolution traffic signal controller data, detector data, conflict monitors, signal cabinet status, and communications equipment status.
This functional object is included in the "ITS Roadway Equipment" physical object.
