Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

Question

Based on the count data shown below, is a traffic signal justified under warrant 1 or warrant 2?
The major road is in the E-W direction and minor road is in the N-S direction. Assume there are
two lanes on all approaches and the major road speed limit is 35 mph.
