Problem 5 - A transit agency is evaluating the average costs and fleet sizes for bus types A, B, and C for various demand (ridership) conditions. Assume that the round-trip travel time is 1 hour for all types of buses. a. (10%) Develop a figure to sketch (numerically) average cost versus volume Q. Average cost is equal to hourly operating cost divided Q, and Q varies from 5 to 100 with an increment of 5 passengers/hour. b. (5%) Determine for what Q values if bus type B is preferable in terms of the least average cost. Operating Cost ($/bus-hour) Bus Type Seat Capacity (seats/bus) 50 45 B 40 40 C 30 35
