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

Discussion:

In problem 1, we've learned the effects of changing the arrival type, we’ve seen what differences in performance might exist if different sets of data are used for the same site, and we’ve seen what you should do to address skipped phases. More generally, we’ve seen that you need to be explicit in describing to the client how you’ve addressed these issues in establishing the base case results. Somebody else might get results that are quite different from yours, depending upon how they address these issues. You’ve got to be careful about the assumptions you make in correctly representing the conditions that exist in the field.
