Shorter design periods may be used when highways are to be constructed in stages or designed for shorter pavement improvement life-spans. Traffic Cooperate with the region's planning staff to develop design traffic data. Traffic data includes current and design year average daily traffic, design hourly volumes, directional distributions, and the percentages of heavy vehicles expected in the design year. Normally trucks and buses are the heavy vehicles considered as influencing highway capacities. Also, consider heavy recreational vehicles on certain routes. Include bicycle and pedestrian counts when requesting intersection traffic counts. Highway Capacity Capacity is an important factor in highway design and operation.
