Optimal passenger demand on bus rapid transit in Tanzania A case of kibaha– gerezani route

This paper examines the effect of optimal Passenger demand (P*) in Transport services using Mathematical model. Numerical analysis of the model shows that the increase in BRT frequency fr trigger decrease in passengers’ cost CP, as well as total cost CT that is combination of operation and passenger costs. The passenger cost increases at the beginning and gradually starts to decrease as well as total CT. In fact, operation cost increases as frequency increases due to fuel consumption, turn out of tires and bus services. Meanwhile, when using optimal passenger demand, passengers’ cost and operation cost are decreasing they exist because, as optimal passenger demand P* increases, BRT frequency also increases and therefore, waiting time is reduced for all passengers. However, operation cost is fixed like paying salary of staff, bus services and other office expenses, but this should be devastating by members of staff to work hard, use of the bus effectively and ensure getting optimal passengers so as to get operation cost and the profit, otherwise the bus will run with loss. From these findings indicate that BRT management should make effort to attract all passengers by reducing value of average waiting time and BRT service ( ), value of waiting time (Vw) and the average time getting on and out of the bus per passenger (Aou).
