Risky driving behaviour (RDB) is one of the human factors that contributes to more road crash fatalities and injuries. Right-turning vehicular drivers with risky driving attitudes considerably increase the crash risk at unsignalized T-intersections. Therefore, this study aimed to investigate the major contributing factors to risky driving behaviour. A questionnaire was developed to obtain the driver's opinion on RDB at unsignalized T-intersections. Multiple correspondence analysis (MCA) was used to understand how factors related to demographics and riding information affect the RDB. The study results showed that male drivers are more dangerous than female drivers. Moreover, the drivers aged between 25 and 44 years with more travel distance and travel frequency showed higher risk-taking behaviour. The study findings also concluded that the travel modes (viz., autorickshaw and truck or bus) are perceived to be more dangerous than the other travel modes. The authors believe that the findings of the present study might be useful for traffic engineers and safety experts to understand the contributing factors to RDB and to take suitable traffic management measures to reduce crash risk at unsignalized T-intersections.
