Question
1. 4 pts] Determine whether this intersection for which data are provided below meets MUTCD Warrants 1, 2, and/or 3 for signalization. These data were collected using pneumatic tubes and the data were binned in 60-minute increments (15-minute data are not available). All approaches have one lane entering the intersection. For any warrants that are met, explain how the warrant was met (rules applied, hours in which the volume criteria were met, etc.). The major street speed limit is 45 mph, and the minor street speed limit is 25 mph. The minor street has only one approach (i.c. it is a T intersection.)

If the intersection satisfies all the three warrants, then only the intersection can be signalized.
Refer the Table no 8.1, 8.2 for warrant 1 and Figure 8.5 for warrant 2 from the text book.
Warrant 1 condition A is satisfied when the volume of vehicles entering major and minor roads satisfy the 100% columns of table 8.1. and also condition B is satisfied when the volume of vehicles entering the major and minor roads satisfy the 100% columns of table 8.2.
Warrant 2 is satisfied when the condition in the figure 8.5 is satisfied for a one lane major and the minor roads.
Warrant 3 is satisfied when total volume of vehicles entering the intersection is equal to or greater than 650 vehicles per hour for three-leg intersections.
From the data given in the table for a three leg intersection,
1. Hour five satisfies warrant 1 condition A and B, warrant 3.
2. Hour six satisfies warrant 1 condition A and B, warrant 3.
3. Hour seven satisfies warrant 1 condition A.
4 Hour ten satisfies warrant 1 condition A.
5. Hour 12 and 13 satisfies warrant 1 condition A.
6. Hour 14, 15 and 16 satisfies both warrant 1 condition A and warrant 3.
7. Hour 17 satisfies warrant 1 condition A.
Hence, the intersection can be signalized.
