A statistical estimation of automobile hydrocarbon emissions by factor analysis was obtained from the results which were reported in our automobile road tunnel survey. As a result, seven common factors were obtained from 27 variable data. These were; vehicle traveling conditions, speed, LPG-powered automobiles, gasolinepowered automobiles, 2-cycle engine automobiles and two background factors. Further, in order to estimate the relative contributions of various types of hydrocarbon pollution sources, regression lines and emission factors were obtained from the statistical estimation.
