4. BARE LANE INDICATOR GUIDELINES ClassificationAADTTarget Regain Time Bare Lane Description Super Commuter Urban Commuter Rural Commuter Primary Secondary Over 30,000 12,000 – 30,000 2,000 – 12,000 800 – 2,000 Under 800 hrs. 1-3 hrs. 2-5 hrs. 4-9 hrs. 6-12 hrs. 9-36 hrs Bare Lanes are defined the same for all classifications as follows: All driving lanes are free of snow and ice between the outer edges of the wheel paths and have less than 1 inch of accumulation on the center of the roadway (See Figure 1, 5-791.310, Bare Lanes – Indicator Value). This is the condition at which most drivers feel safe and comfortable when driving at posted speeds. The Bare Lane Regained date and time should be logged when this condition is obtained.

5. Event Definition A winter weather occurrence that consumes resources necessary to prevent, minimize or regain the loss of bare lanes. Night and dawn patrol S&I operations will not trigger an event until additional crews are called in. Event can be a result of one or more of the following conditions: rain, sleet, snow, drifting snow, frost or ice.

6. Bare Lane Definition All driving lanes are free of snow and ice between the outer edges of the wheel paths and have less than 1 inch of accumulation on center of the roadway. This is the condition at which most drivers feel safe and comfortable when driving at posted speeds. Note: Cannot have snow or ice between wheel tracks.

7. Bare Lane Between Wheel Paths * All driving lanes must be in this condition * The entire route must be in this condition No greater than 1 inch Accumulation on center-line
