Operating styles, working time and daily driving distance in relation to a taxi driver's speeding offenses in Taiwan.

This study explored the determinant factors of taxi drivers' speeding violations in Taiwan. Data were gathered from a nation wide survey and included 6923 professional taxi drivers in 2006. The results indicated that 96.6% were males and 92.5% had less than a college level education. Daily working hours were from 2.5 h to 15 h with a mean of 10.12 h. The data also indicated that taxi drivers worked approximately 27.35 days and only took 2.65 days rest per month. Of the observed taxi drivers, 25.6% reported at least one speeding violation in a one-year period. The results of a generalized linear model (GLM) revealed that the determinant factors associating with a taxi driver's speeding violation were not related to gender or educational level. However, age, job experience, operating styles, kilometers driven daily, driving late at night, and monthly off duty days were significantly associated with committing the speeding violations.
