Traffic volumes are typically rounded up to the nearest 100 unit (e.g., vehicle, truck) but are rounded up to the nearest 50 if the traffic volumes are between 100-200. Traffic volumes are typically rounded up to the nearest 10 or 25 if traffic volumes are under 100. However, using numbers under 100 may cause balancing issues. It is recommended that identical volumes be rounded to the same value. Additionally, identical volumes typically result in the same values when forecasted.
