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 1-51 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.
