What does K factor represent in traffic volume studies?

• A. Percentage of traffic during the peak hour
• B. Number of vehicles during off-peak times
• C. Average annual daily traffic
• D. Speed of traffic flow

Answer: (A)

The K factor in traffic volume studies refers specifically to the percentage of the daily traffic volume that occurs during the peak hour. It is an important metric used by traffic engineers and planners to understand traffic patterns, assess roadway capacity, and make informed decisions about infrastructure improvements and traffic management strategies. By analyzing the K factor, engineers can determine what portion of the daily traffic demands are concentrated in peak periods, which is crucial for developing models that predict congestion and traffic flow conditions. Understanding the K factor helps in estimating future traffic conditions based on past and present data. The other choices, while related to traffic studies, do not define the K factor. The number of vehicles during off-peak times, average annual daily traffic, and speed of traffic flow are all significant metrics in their own right but do not capture the specific meaning of the K factor in the context of peak hour traffic analysis.
