School zones have been identified as vulnerable area due to lack of safety measures observed in Bangladesh. To ensure the safety of school going children, reduction of vehicle speed near school area is essential. For this purpose, average speed variation of vehicles in different time, different days of a week both on highway and arterial are investigated in this research. t-test was performed considering 90% confidence interval for both equal and unequal variances. Results indicate that average speed varies significantly between highway and arterial at different times and different days. Based on the results, countermeasures are proposed to improve road safety scenario in school zones.
