Analyzing the Effects
of Signal Phasing
Step 1. Setup
our initial analysis of the Reitz Union Drive improvement strategy (see
Exhibit 5-23) that the most urgent deficiency is the
eastbound left-turn movement, with an estimated delay in excess of 200
seconds per vehicle. The first mitigating option that would be the easiest
to implement and the least costly would be to simply modify the signal
phasing. We can test if providing a signal phase to alleviate the
saturated movements might reduce the delay on those movements,
being cognizant of the effects on the overall intersection.
a few minutes to determine a phasing plan that would reduce the delay of the
critical movements. Click continue when you are ready to proceed.
