About this document
Understanding Levels of Service in Traffic by Max Drake is a document available to read on EtoBox.
This document defines levels of service (LOS) which describe operating conditions for traffic facilities using letters A through F. LOS A represents free-flowing traffic with little delay while LOS F describes breakdown conditions with long queues and stop-and-go traffic. Key measures used to define LOS include speed, density, delay, and flow rate. Six levels are defined with LOS A having the best conditions and LOS F being the worst case scenario.
