11. If a time-scan model is based on scanning time on a regular basis, what is an event scan model based
on? For a signalized intersection, list some events of interest that would be the basis for an event scan
model.
12. For what kinds of problems or system conditions would you consider using the following models:
Critical Movement Analysis, Highway Capacity Manual, and VISSIM?
13. Which model would you use to test signal timing strategies for a congested arterial with three closely
spaced signals? Why?
