Case 1: In recent years, the demand for using app-based ride-sharing transportation services is increasing day by day. As a convenient mode of transportation, both male and female passengers are now easily moving from one place to another place by calling the app-based ride-sharing transportation services (e.g., Pathao, Uber, Obhai, Obon, etc) in Bangladesh. However, it is noticed from the general observation that the ratio of using the app-based ride-sharing transportation services by female passengers is very poor compared with the male passengers.
