Figure 4C-1. Warrant 2, Four-Hour Vehicular Volume

This figure shows a graph depicting numerical values for Warrant 2, Four-Hour Vehicular Volume (see Section 4C.03 for further details). The figure displays three curves—one for each existing combination of approach lanes: one lane and one lane, two or more lanes and one lane, and two or more lanes and two or more lanes.

The table below shows the approximate vehicles per hour (VPH) on the major street and corresponding VPH on the minor street for each combination of approach lanes.

 

Table for Figure 4C-1
One lane and one lane Two or more lanes and one lane Two or more lanes and two or more lanes
VPH on the major street (Total of both approaches) VPH on the minor street (Higher volume approach) VPH on the major street (Total of both approaches) VPH on the minor street (Higher volume approach) VPH on the major street (Total of both approaches) VPH on the minor street (Higher volume approach)
1400 80 1400 80 or 115* 1400 115
1300 80 1300 90 or 115* 1300 115
1200 80 1200 100 or 115* 1200 145
1100 80 1100 120 1100 165
1000 100 1000 150 1000 200
900 120 900 175 900 240
800 150 800 200 800 275
700 180 700 250 700 340
600 220 600 290 600 390
500 260 500 340 500 460
400 310 400 390 400 Not available

* Note: 115 vph applies as the lower threshold volume for a minor-street approach with two or more lanes and 80 vph applies as the lower threshold volume for a minor-street approach with one lane.
