Question

Use Time-Space Diagram to solve the following problem. Develop a two-way bus service scheme on the route {A B C: C B A} that will have regular departure from A, but buses continuing on from B to C will depart less frequently. Some buses will be turned back at B and will return to A without continuing on to C. Passengers from A to C should not transfer at B but they may be delayed at B.

If the target service frequencies on A B are 12 buses/hr in each direction, and on
B C, 8 buses/hr, and if the trip time from A B, B A, C B, B C are each 30 minutes, then depict a set of bus trajectories that will meet these requirements with regular headways on all legs. You need to determine how much to delay each bus at B, and if a bus just came from A, whether to turn it around at B.

what size of bus fleet is required to accommodate your schedule. [Assume: dwell time (time for boarding and alighting) at A, B, C is negligible in the Time-space diagram] Draw Time-Space Diagram directly on an engineering sheet
