What are the future conditions of the cor idor forec Est to be? F/F C/F Existing and Future Level of Service (LOS) Definition Capacity analysis results identify o Level of Service (LOS), which indicates the quality of traffic flow through an intersection. Intersections are given a ranking from LOS A through LOS E The LOS results are based on average delay per vehicle. LOS A indicates the best traffic operation, with vehicles experiencing minimal de s. LOS F indicates an intersection where demand exceeds capacity, or a breakdown of traffic flow. In the Twin Cities Metropolitan area, L05 A through O is generally acceptable by drivers. The standard delay threshold values are identified in the following table: ;Service ;;� ignation Average Control Delay per Vehicle (seconds) '` Average Control Delay;- per Vehicle (seconds) Description of Tra Conditions A B C D E F Less than or equal to 10 > 10 -20 > 20 -35 > 35 -55 > 55 -80 Over 80 Less than or equal to 10 > 10 -15 > 15 -25 > 25 -35 > 35 -50 Over 50 Stable Flow - Low delays; at traffic signals most vehicles do not stop; acceptable LOS Stable Flow - Low delays; at traffic signals some vehicles most stop; acceptable LOS Stable Flow - Moderate delays; at traffic signals some cycle failures; many vehicles must stop; acceptable LOS Approaching Unstable Flow — Moderate delays; at traffic signals cycle failures become noticeable; many more vehicles must stop; limit of acceptable LOS Unstable Flow - Significant delays; at traffic signals cycle failures are frequent; most vehicles required to stop; unacceptable LOS Forced Flow /Failure - Significant delays; at traffic signals many cycle failures occur; most or all vehicles must stop; unacceptable LOS 0 to 12,000 CC Y ca J Future o E Lowed Density N -C Residential Future High Density Residential it14,20 F, 10,000 Acr :17-v Legend = Signal • = All -way Stop = Side Street Stop x,xxx = 2030 No-Build Daily Traffic Volumes Level of Service - LOS X AM X PM A/B Overall LOS/ Worst Approach LOS Vehicle /Capacity (V /C) Analysis V/C ratios are a common measure of roadway traffic capacity levels. In a V/C analysis, average daily traffic volumes (ADT) are compared to roadway capacity thresholds to identify existing and future traffic problems. The commonly used capacity threshold for a 2 -lane undivided facility such as CSAH 34 is a maximum ADT of 10,000 to 12,000 vehicles per day. Based on forecasted traffic volumes for CSAH 34, the entire corridor will be at or over capacity by 2030. Attachment 2 CSAH 34 Corridor Stud in Lino Lakes
