• Required input data– Basic inputs such as
AADTT, % truck, and Operation speed
– Traffic volume adjustment factors such asMonthly adjustment, class distribution, and hourly distribution
– Other general traffic inputs such asAxle numbers for single, tandem, tridem, and quad axle groups Axle load distribution, andAxle configuration
