Table 1: Level of Service for Signalized and Unsignalized Intersections LOS Designation Signalized Intersection Unsignalized Intersections Average Delay/Vehicle(seconds) Average Delay/Vehicle(seconds) A <_ 10 <_ 10 B > 10-20 > 10- 15 C > 20-35 > 15-25 D >35-55 > 25-35 E > 55-80 >35-50 F > 80 > 50 For side-street stop-controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach.Traffic operations at an unsignalized intersection with side- street stop control can be described in two ways. First,consideration is given to the overall intersection LOS. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support these volumes. Second,it is important to consider the delay of the minor approach. Since the mainline does not have to stop, the majority of delay is attributed to the side- street approaches. It is typical of intersections with higher mainline traffic volumes to experience high levels of delay (poor levels of service) on the side-street approaches, but have an acceptable overall intersection level of service during peak hour conditions. Results of the existing intersection capacity analysis, shown in Table 2, indicate that all study intersections currently operate at an acceptable overall LOS C or better during the weekday peak hours. 6
