Investigating Effects of Temporal and Locational Factors on Traffic Violations of Taxi Drivers: Data from Off-Site Enforcement Camera System

From temporal and locational perspectives, the influence factors of traffic violations for taxi drivers remain unclear. Hence, this study attempts to investigate the effects of temporal and locational factors on traffic violations of taxi drivers using descriptive statistics and Chi-square test based on data extracted from the off-site enforcement camera system during the year 2016 in Luzhou, P.R. China. The results show that the most common traffic violation of taxi drivers is "use of an improper oriented lane"; season, day of week, time of day, road type, and road segment have varying influences on traffic violations of taxi drivers. Apart from speeding that mainly takes place on the secondary highway in the urban settings, the other traffic violations largely happen on the urban road. The findings of this study imply that traffic supervisions and interventions specifically proposed for traffic violations of taxi drivers should consider the appropriate time and location.
