Which factor is NOT considered in traffic volume studies?

Step 1: Understand what traffic volume studies are. They measure how many vehicles use a road over a certain period.
Step 2: Identify the factors that are usually considered in these studies. Common factors include time of day (when traffic is heavy or light), weather conditions (like rain or snow), and vehicle classification (types of vehicles like cars, trucks, etc.).
Step 3: Recognize that not all factors are relevant. For example, the type of road surface (like asphalt or concrete) is not usually a direct factor in measuring traffic volume.
Step 4: Conclude that while some factors are important for understanding traffic patterns, road surface type is not one of them.
