Abstract：The national comparison of non-contact speed meters was finished in 2018. The pilot lab was National Institute of Metrology, China. As the first comparison of fixed measurement spot type in on-site speed measuring metrology, 29 participating laboratories were involved, among which 27 were provincial level metrological institutes. All participating laboratories got satisfied results. The technical background and comparison program were introduced, the comparison method and uncertainty components were studied, the metrological particularities of speed measurement were proposed, and the comparison results were analyzed.

Key words： metrology vehicle speed measurement comparison non-contact speed meter normalized error
