What is the primary function of the K factor in traffic analysis?

• A. To estimate average speed
• B. To determine peak hour traffic
• C. To analyze vehicle types
• D. To assess road conditions

Answer: (B)

The primary function of the K factor in traffic analysis is to determine peak hour traffic. The K factor represents the ratio of the average hourly volume over a specific period, typically a 24-hour period, to the peak hour volume during that same time frame. This ratio helps traffic engineers and planners understand the distribution of traffic flow throughout the day and identify when congestion is most likely to occur, thereby allowing for better design and management of roadways to accommodate peak traffic demands. In practice, the K factor is essential for effective traffic forecasting, modeling, and capacity analysis, which ensures that road infrastructure can handle fluctuations in traffic volume. By accurately determining peak hour traffic, planners can make informed decisions regarding road capacity, signal timing, and other traffic management strategies that enhance roadway efficiency and safety.
