Traffic volume – traffic flow rate in vehicles per hour. Freeway capacity – the maximum sustained 15-minute flow rate, expressed in passenger cars per hour per lane, that can be accommodated by a uniform freeway segment under prevailing traffic and roadway conditions in one direction of flow. Level of service (LOS) – qualitative measure and ranking of the traffic operational conditions experienced by users of a facility under specific roadway, traffic, and traffic control (if present) conditions. Current practice designates six levels of service ranging from A to F, with level of service A representing the best operating conditions and level of service F the worst. Free-Flow Speed (FFS)
