This three-leg intersection is analyzed assuming 2 lanes on the major street approach and 1 through lane on the minor street approach, resulting in the following:
Warrant #1. Only 1 hour of the 8 collected in the TMC data set exceeded the warrant #1 threshold shown in OMUTCD Table 4C-1 condition B, and combo warrant (evaluated at 80%). Warrant #1 is NOT satisfied.
Warrant #2. Plotting the four highest volume-pairs as described in the methodology section on top of OMUTCD Figure 4C-1 (Figure 9A) resulted in only one volume pair exceeding warrant #2 threshold for both the 100% and 70% volume thresholds. Warrant #2 is NOT satisfied.
Warrant #3. Plotting the highest volume-pair as described in the methodology section on top of OMUTCD Figure 4C-3 (Figure 9B) resulted in the volume pair exceeding warrant #3 threshold utilizing a 70% threshold allowable for an existing traffic signal. Warrant #3 is satisfied.
