Memorandum: Footlab Focused Traffic Analysis 3 January 24, 2025 the transportation solutions company...the average delay experienced by vehicles traveling through an intersection, whereas for unsignalized intersections, the LOS is based on the worst approach where the minor leg has a shared lane and on the worst movement where the minor leg has dedicated turn lanes. Table B presents a brief description of each level of service letter grade, as well as the range of delays associated with each grade. Table C: LOS Criteria LOS Description of Drivers’ Perception and Traffic Operation Delay in Seconds Unsignalized Signalized A This level is typically assigned when the volume-to-capacity ratio is low and either progression is exceptionally favorable, or the cycle length is very short. If it is due to favorable progression, most vehicles arrive during the green indication and travel through the intersection without stopping. < 10 < 10 B This level is assigned when the volume-to-capacity ratio is low and either progression is highly favorable, or the cycle length is short. More vehicles stop than with LOS A. > 10 and < 15 > 10 and < 20 C This level is typically assigned when progression is favorable, or the cycle length is moderate. Individual cycle failures (i.e., one or more queued vehicles are not able to depart as a result of insufficient capacity during the cycle) may begin to appear at this level. The number of vehicles stopping is significant, although many vehicles still pass through the intersection without stopping. > 15 and < 25 > 20 and < 35 D This level is typically assigned when the volume-to-capacity ratio is high and either progression is ineffective, or the cycle length is long. Many vehicles stop and individual cycle failures are noticeable. > 25 and < 35 > 35 and < 55 E This level is typically assigned when the volume-to-capacity ratio is high, progression is unfavorable, and the cycle length is long. Individual cycle failures are frequent. > 35 and < 50 > 55 and < 80 F This level is typically assigned when the volume-to-capacity ratio is very high, progression is very poor, and the cycle length is long. Most cycles fail to clear the queue. > 50 > 80 The City endeavors to maintain LOS D as the minimum level of service standard at intersections of collector or higher classification. Existing Levels of Service The levels of service for existing conditions were calculated using the existing lane geometrics and existing traffic volumes. The existing levels of service at the study intersections are shown in Table D. As shown in Table D, all intersections are currently operating at satisfactory levels of service. LOS worksheets are included in Appendix E.

LOS = Level of Service Existing With Project Levels of Service The levels of service for existing with project conditions were calculated using the existing lane geometrics and existing with project traffic volumes. The existing with project levels of service at the study intersections are shown in Table D. As shown in Table D, all 3
