Level of service (LOS) is a qualitative measure used to relate the quality of motor vehicle traffic service. LOS is used to analyze roadways and intersections by categorizing traffic flow and assigning quality levels of traffic based on performance measure like vehicle speed, density, congestion, etc.
It contains concepts, guidelines, and computational procedures for computing the capacity and quality of service of various highway facilities, including freeways, highways, arterial roads, roundabouts, signalized and unsignalized intersections, interchanges, rural highways, and the effects of mass transit, pedestrians, and bicycles on the ...
This process is a vast improvement upon pedestrian level of service (LOS) indicators, recommended within the Highway Capacity Manual. [54] However it may not translate well to non-Western locations where the idea of "optional" activities may be different. [55]
Walk Score was founded in July 2007 by Mike Mathieu [3] [4] and aided by Matt Lerner, Jesse Kocher, and Josh Herst, formerly of Madrona Venture Group.. In August 2010, the company launched Transit Score to help users understand the proximity of public transport to an address.
The ICU method uses the Level of Service concept, in which reports on the amount of reserved capacity or capacity deficit. In order to calculate the Level of Service for the ICU method, the ICU for an intersection must be computed first. [3] ICU can be computed by: ICU = sum(max (tMin, v/si) * CL + tLi) / CL = Intersection Capacity Utilization
Levels of service (LOS) is a term in asset management referring to the quality of a given service. Defining and measuring levels of service is a key activity in developing infrastructure asset management plans. [2] [3] [4] Levels of service may be tied to physical performance of assets or be defined via customer expectation and satisfaction.

The public transport accessibility level (PTAL) is a method sometimes used in United Kingdom transport planning to assess the access level of geographical areas to public transport. PTAL is a simple, easily calculated approach that hinges on the distance from any point to the nearest public transport stop, and service frequency at those stops.
