Appendix C 2.2 Traffic Data
Traffic – 1800 AADT, including 35% heavy vehicles consisting of:
- standard heavy vehicles = 35% (HV)
- large heavy vehicles = 0% (LHV).
The road section is two-lane, two-way, with an even split of traffic in each direction, over a width of 7.6 m. Thus the design traffic is 1800/2 = 900 v/l/d.
Therefore, using Equation 2 (Section 5.2.5), EHV (%) can be calculated:
| EHV (%) | = | SHV(%) + (LHV(%) x 3) |
| = | (35) + (0 x 3) | |
| = | 35%. |
