Automated Traffic Signal Performance Measures (ATSPM) are an emerging technology promoted by the FHWA in the fourth round of their Every Day Counts (EDC-4) initiative. The technology and its benefits are described by the FHWA as "a high-resolution data-logging capability added to existing traffic signal infrastructure and data analysis techniques. This provides agency professionals with the information needed to proactively identify and correct deficiencies." Additionally, the technology once implemented can reduce agency costs on software modelling and manually collected data currently used for signal retiming.
Two leaders in integrating the technology are Utah UDOT and Georgia GDOT, with Utah developing a software that is used by both agencies, along with others in the US in the process of implementing.
