Traffic volumes/operations

The analysis of existing and future operating characteristics of a roadway can be measured using Level of Service (LOS) to provide an indication of the ability of the roadway to satisfy both existing and future travel demand.

LOS is a quantitative measure of the quality of service of a transportation facility. The LOS measure is broken down into six letter grades, “A” through “F” with “A” being the best and “F” being the worst. LOS measure of D/E is considered the lowest acceptable rating for an intersection.

• LOS descriptions
• 2035 LOS peak hour operation summary
