Sub-problem 3a: Oversaturated Intersection Analysis
We now consider the performance of the intersection for each
of the four 15-minute time periods with the proposed signal control. The
results for the first 15-minute time period (4:00 pm to 4:15 pm) are shown in
Exhibit 1-29:

For this first time period, while there is some delay on
the side streets, the intersection operates at acceptable levels of service. Continue to the next page to see the results of the analysis for the second time period.
