What does the Highway Capacity Manual provide guidelines for?

The Highway Capacity Manual offers comprehensive guidelines on how to compute highway capacity, focusing on methods for estimating the maximum volume of traffic that can be accommodated on a roadway under various conditions and configurations. This includes detailed methodologies for assessing the performance of different types of roads, analyzing traffic flow, and understanding factors that affect capacity such as traffic demand, roadway design, and environmental conditions.

While safety measures, environmental impact assessments, and funding allocations are crucial components of transportation planning and management, they are not the primary focus of the Highway Capacity Manual. Instead, this manual specifically aids transportation engineers, planners, and researchers in determining how efficiently highways can handle traffic, which is essential for effective transportation system planning and operations.
