_XISTING LEVEL * Delay measured in seconds per vehicle A level of service (LOS) analysis was conducted for the intersection. LOS indicates the quality of traffic flow through an intersection. The LOS results are based on the average delay per vehicle that goes through the intersection. Intersections are given a ranking of LOS A through LOS F. The level of service system is set up similar to a report card with W representing the highest quality operations and "F" representing the poorest operations. At LOS A, motorists experience very little delay or interference. On a roadway or intersection with LOS F conditions, motorists would experience severe congestion and extreme delay, i.e., gridlock. Although LOS A conditions represent the best possible level of traffic flow, the cost to construct intersections to such a high standard exceeds the benefit to the user. Within an urbanized or urbanizing area, it is generally regarded that LOS D provides an acceptable level of service. For intersections, level of service is primarily a function of delay which is dependent on volumes, intersection lane configuration, and traffic control. The intersection analysis was completed using average control delay as defined by the HCM. The threshold delay values for each level of service for unsignalized intersections are slightly less than for signalized intersections because motorists' expectations of the intersection differ with the type of traffic control. The level of service analysis criteria for signalized and unsignalized intersections are explained in the table below. County Road B2 &Lexington Avenue Intersection Reconstruction 1 RAlic MwE Y COUNTY
