Cities in Kerala, like many other Indian cities, account for a high percentage of two-wheelers (about 65% of new vehicle registrations in a year are two-wheelers) but adequate measures to ensure their safety are seldom undertaken. This results in higher involvement of two-wheelers in crashes (approximately 42.5% of crashes involved two-wheelers as per Kerala Police records, 2020). The two-wheelers are at high risks on the road especially so at the intersections. T-intersections account for about 9.76% of crashes as per MoRTH 2019. Through this study, a novel approach, developed abroad, was applied to T-intersections whose implementation can ensure better safety and priority to two-wheeler users. This study presents the impact of implementing two-wheeler boxes at T-intersections and evaluates its effectiveness using micro-simulation tool and Surrogate Safety Assessment Model. The study area chosen is Kowdiar, a signalized T-intersection, situated in Thiruvananthapuram, Kerala, India. Video analysis was used to extract the traffic parameters at the junction which was employed for the calibration and validation of the base model in VISSIM software. Modified model, with inclusion of  two-wheeler box giving priority to two-wheelers, was developed and compared with the base model. The comparative analysis showed that the modified model was beneficial over the base model due to about 25.6% reduction in number of possible conflicts, higher values of surrogate safety measures, 22.1% reduction in average queue length and improved saturation flow. Therefore, this study makes a case for the implementation of two-wheeler boxes at signalized T-intersections with mixed traffic conditions.
