Sub-problem 3a: Shenendehowa Campus AM & PM
peak - Existing Conditions
Exhibit 2-32 shows the results of our sensitivity analysis for the PM
Existing condition. The overall delay doesn’t change very much. It
ranges from 19.4 sec/veh up to 24.1. The delays for the individual movements
are similar except for the eastbound left-through. It varies from 20.2 to
31.1 sec/veh. That’s a 50% change.

Discussion:
 Consider
the table shown above. These analyses show variations in results that were
obtained by making slightly different assumptions and using different inputs
for the peak hour factor.
