Part I – Bus Service Planning
Fishermans Bend is served by three bus lines, 235, 237, and 606. More information about these services, such as timetables, can be found in the links below.
235 City – Fishermans Bend via Williamstown Road
237 City – Fishermans Bend via Lorimer Street
606 Elsternwick Station – Fishermans Bend
Question 1 (20 pts): Based on the timetables, for each line, what is the service (a) frequency, (b) headway, (c) expected waiting time, and (d) capacity (each car can take 56 people)?
Question 2 (5 pts): Considering a load factor of 0.9, what was the design volume at peak load point for each one of the lines?
Question 3 (5 pts): For each line and each direction (total of 6 services), when is the peak period? How did you infer that?
Question 4 (25 pts): Based on the information available at “Fishermans Bend Framework – Assignment_v2”, by how much do you expect the demand for these services to grow by 2025 and by 2050? Explain your rational and clearly state your assumptions. What service frequencies would be required to serve the new demands?
Part II – Intersection and Signal Design
Question 5 (45 pts): For this part of the assignment, you will work with the same sub-precinct as in Assignment 1.
• Student ID # ending with 0 or 1 = Montague
• Student ID # ending with 2 or 3 = Lorimer
• Student ID # ending with 4 or 5 = Sandridge
• Student ID # ending with 6 or 7 = Wirraway
• Student ID # ending with 8 or 9 = Employment
The Fishermans Bend renewal project includes two new tram routes, as shown in the figure below.
Select one intersection in your sub-precinct where the tram line will pass and design the signal timing plan (provide the street names). Your answer should include the intersection representation, phase diagram, and list of modes of transport being considered (justify). You should define the movements and mode specific volumes based on an informed guess and provide a justification.
1. Identify peak hour volumes and peak 15-minute volumes for the various movements.
2. Decide on a phasing plan.
3. Calculate the length of the intergreen period for each phase of your cycle.
4. Calculate the minimum green time for each phase based on the pedestrian crossing time.
5. Calculate or measure the saturation flow rate for each approach or lane.
6. Calculate the design flow rate for each approach or lane using the peak hour volume and peak hour factor.
7. Find the critical movements or lanes, and calculate the critical flow ratios.
8. Calculate the optimum cycle length.
9. Allocate the available green time using the critical flow ratios.
10. Calculate the capacity of the intersection approaches or lanes.
11. Check the capacities/design flow rates and green intervals/minimum green intervals. Adjust your cycle timing scheme if necessary.
