We developed an analytical method for the detection of nitric oxide (NO), nitrogen dioxides (NO2) and ozone (O3) simultaneously with high time resolution (1 s). The fast analytical method was applied for the observation at the Fuji mountain roadside at an altitude of 2300 m. We successfully observed the concentrations of NO and NO2 in emissions from each vehicle at a roadside, and the O3 concentration decreased due to the reaction with NO. Relative amounts of NOx emissions and primary NO2 emission ratios of each vehicle driven on the road were estimated by the concentrations observed with high time resolution.
