Sub-problem 6b: Planning Analysis at Styner-Lauder Avenue

The twenty-year projected volumes for the Styner-Lauder Avenue intersection, adjusted for the peak hour factor are shown in Exhibit 1-49.

Approach LT (veh/hr) TH (veh/hr) RT (veh/hr)

Click here to see the cross-product calculations. None of the left-turn cross products suggests any need for left-turn protection, so a two-phase operation will be used.

 

Exhibit 1-50 shows the results from this exercise. Even with the 20-year traffic volume projections, the critical v/c ratio is only 0.52. These results let us say with great confidence that the existing intersection configuration will be able to accommodate the anticipated traffic 20 years from now with no operational problems or congestion.
