Level of Service Descriptions Level of Description of Operation Range of Service /C Ratios Free flow. Individual users are virtually unaffected by the presence of others in the traffic A stream. Freedom to select desired speeds and to maneuver within the traffic stream is 0.00 — 0.60 extremely high. The general level of comfort and convenience provided to the motorist, passenger, or pedestrian is excellent. Stable flow. The presence of other users in the traffic stream begins to be noticeable. Freedom to select desired speeds is relatively unaffected, but there is a slight decline in the B freedom to maneuver within the traffic stream from LOS A. The general level of comfort 0.61 — 0.70 and convenience provided is somewhat less than that of LOS A, because the presence of others in the traffic stream begins to affect individual behavior. Stable flow. This LOS marks the beginning of the range of flow in which the operation of individual users becomes significantly affected by interactions with others in the traffic C stream. The selection of speed is affected by the presence of others, and maneuvering within 0.71 — 0.80 the traffic stream requires substantial vigilance on the part of the user. The general level of comfort and convenience declines noticeably at this level. High density, but stable flow. Speed and freedom to maneuver are severely restricted, and D the driver or pedestrian experiences a generally poor level of comfort and convenience. 0.81 — 0.90 Small increases in traffic flow will generally cause operational problems at this level. Operating conditions at or near the capacity level. All speeds are reduced to a low but relatively uniform value. Freedom to maneuver within the traffic stream is extremely difficult, and generally accomplished by forcing a vehicle of pedestrian to "give way" to E accommodate such maneuvers. Comfort and convenience levels are extremely poor, and 0.91 — 1.00 drivers or pedestrian frustration is generally high. Operations at this level are usually unstable because small increases in flow or minor variations within the stream will cause a breakdown. Forced or breakdown flow. This condition exists wherever the amount of traffic approaching F a point exceeds the amount which can traverse that point. Queues form up behind such > 1.00 locations as arrival flow exceeds discharge flow. ADDITIONAL TRAFFIC ANALYSIS REQUIREMENTS (PROJECT SPECIFIC) • Evaluate the potential driveway entrance congestion going into the lot from "X ROAD". The southeast parking lot, on the corner of "Y ROAD" and "X ROAD", can possibly cause an obstruction in the entrance to the lot. Vehicles parked in the southeast parking lot, especially those in accessible (ADA) parking near the entrance that are backing out of their parking space can prevent vehicles from entering the parking lot. As a result, other vehicles behind will be held back thus creating a traffic jam. This may cause an overflow of vehicles in the parking lot entrance, leading to vehicles being backed up all the way to the "X ROAD" entrance as well. • Vehicles that are exiting the lot making a left onto "X ROAD" can potentially be hazardous. Having a raised medium on "X ROAD" will restrict vehicles from making that left turn out of the lot. In result, there will need to be a path identified for those vehicles exiting the lot to head eastbound. 3
