Abstract

This study used JASP Software for descriptive analysis and Chi-square tests. I surveyed 100 people of different backgrounds and age for their opinions. It determined that 56% of respondents were dissatisfied with the public transportation service, and 69% used public transportation daily. According to this study, 82% of people regularly experience traffic jams because it is hard to get to places, especially in places like Mirpur. Even though 64% of those who responded used buses as public transport, but only 18% wanted more buses to help ease traffic. They would rather see digital transportation systems, awareness and safety improvements. Notably, 80% of those who answered think improving public transportation services could help reduce the traffic jams in Dhaka city.

Abstract

This research investigates helmet usage rate and motorcyclists’ awareness of road safety laws regarding helmet usage in the Darial Union of Bakerganj Upazila, Bangladesh. A structured questionnaire collected data from 100 participants representing various age groups and professions. Then, data analysis using JASP software revealed significant gaps in helmet usage and awareness of road safety laws regarding helmet usage, particularly among younger individuals aged 15-20 and motorcycle drivers. At the same time, older participants (aged 41 and above) demonstrated higher helmet usage and better understanding; younger riders and those in high-risk professions, such as motorcycle drivers, students, and the unemployed, needed to be more informed and compliant with safety practices. The findings highlight the importance of focused educational efforts and training programs to promote helmet use and raise road safety awareness, particularly in Darial Union's rural districts.
