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 VPH on the major street and corresponding VPH on the minor street for each combination of approach lanes.
| 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.
