Capacity and level of service are critical concepts in transportation facilities providing insights into traffic management. Capacity focuses on the maximum volume the road can accommodate, while level of service offers a qualitative measure of driving conditions. Various factors influence these metrics, including traffic composition, roadway geometric characteristics, and control conditions. The Highway Capacity Manual classifies levels of service from A to F, delineating driving comfort and system efficiency.
