Recently, China has made a series of key breakthroughs in the field of optical parameter measurement technology for traffic safety. Relying on the key laboratory of the State Administration of Market Supervision and Administration established by the Shaanxi Provincial Institute of Metrology, based on the strategic layout of the “Strong Traffic Country” and “Safe China”, we have carried out systematic research on measurement bottlenecks such as “undetectable, incomplete, and poor measurement” where parameters such as visibility, reverse reflection, and glare have existed for a long time, breaking through the core technical barriers in the quantitative traceability system, and successfully developed a series of key optical parameter calibration devices. An optical measurement and measurement technology system for traffic safety was initially constructed to better protect traffic safety.
