Sub-problem 2b: Analyzing the Effects of Signal Phasing

Step 1. Setup

Remember from 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.

Discussion:
Take 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.
