Sub-problem 1a: Maxwell Drive PM Peak Hour - Existing Conditions

Skipped Phases
Most actuated controllers are capable of skipping phases. If no traffic is present to call the phase, the controller moves on to the next movement or returns to a rest condition. This presents a challenge for most analytical analysis methodologies that examine an average cycle for the signal. We are going to look at skipped phases from the following perspectives:

What happens if you ignore skipped phases?

Discussion:
Think of some other traffic analysis models with which you are familiar. How do they deal with skipped phases? Is simulation a good way to study this issue? What might be the problems in using simulation? If you did use simulation, how many cycles would you need to study to obtain credible information about the signal's performance? Would you need to do multiple runs? Using multiple seeds?
