Abstract

Road traffic crashes remain a significant global issue, disproportionately affecting developing countries. Among these, intersection-related crashes, particularly unsignalized intersections, experience higher crash risks than their signalized counterparts. This study investigates the influence of collision type, road geometry, light condition, gender, and day of the week on traffic crashes at unsignalized intersections in the Dhaka Metropolitan Area (DMA) between 2018 and 2020. Using crash data from the Accident Research Institute (ARI) at BUET. They were collected through MAAP5 software. The analysis highlights that pedestrian-vehicle collisions dominate with 59% of total collisions. Despite their relatively lower traffic volumes, T-junctions emerged as a critical geometric factor contributing to 12% of crashes. Environmental conditions, such as daylight and nighttime, significantly influenced crash occurrences, with daylight witnessing the highest frequency at 54.5%. Weekdays showed a higher crash frequency, particularly on Monday, Tuesday, and Thursday, with gender analysis revealing a predominance of 79% male victims. Casualty hotspots were identified in critical areas such as Jatrabari, Tejgaon, and Uttara West Thanas. The study also highlights areas of pedestrian-vehicle collisions, where pedestrians face high fatality risk. The findings emphasize the elevated risks associated with unsignalized intersections. It is recommended that improving intersection design and enforcing traffic rules could significantly reduce crash risks. Future research should consider additional factors with advanced techniques to mitigate unsignalized intersectional crashes.
