MAJOR STREET
Step 1
Calculate the total traffic volume on all the lanes, including major and minor streets.
Step 2
Check volume as per the given warrant that it is coinciding the value plotted in the graph. The given values of the traffic volume should be checked corresponding to the warrant 2, Four hour vehicular volume.
Step 3
For an intersection to meet the given warrant criteria, 4 hourly values should coincide with graph.
Which in our case only two are meeting 7-8AM and 2-3 PM.
Therefore, the intersection does not meet signal warrant 2.
