Chapter 10: Your Final Design: Putting It All Together
325
The purpose of this activity is to give you the opportunity to assemble information that you have prepared
in previous design activities into a form that will help you to prepare your final report and presentation.
•
Prepare a timing plan for an isolated actuated signalized intersection based on an analysis of traffic flow
quality and intersection performance for a range of timing parameter values and phasing alternatives
•
Results from previous design activities
•
Prepare an Excel spreadsheet that includes your design values, as well as the tables and charts that
support the selection of your design values
Tab 1:
Title page with activity number and title, authors, and date completed
Tab 2:
Phase timing sheet that includes the timing parameters for each phase: minimum green time,
vehicle extension time, maximum green time, yellow time, and red clearance time
Tab 3:
Ring barrier diagram showing your recommended phasing plan
Tab 4:
Intersection sketch showing geometry, vehicle movements, and phase numbering
Tab 5:
Performance data (delay and queue length data) that compares each step in your design process
Assemble the design elements that you developed as part of the activities listed in Table 35.
Activity Design elements
28 Base network conditions
36 Maximum allowable headway
37 Passage time
43 Maximum green time
50 Left turn treatment
56 Yellow and red clearance times
Table 35.
Activities and design elements
Prepare a side-by-side comparison of the performance of the base case and each of the iterations of your
design. The comparison should include the performance measures (delay and queue length) that you used
previously in these activities.
