Assigning Winter Level of Service State Long Range Transportation Plan (SLRP) is the basis for assigning LOS Designates routes into International, national, statewide, regional, and local significance MDOT used these designations for assigning winter LOS The SLRP is available at michigan.gov/mdot

SLRP Designation Factors ADT Commercial ADT Total Population Total Employment Tourism Airports Carpool Lots Intermodal Freight

Level of Service at Risk Limited funding means MDOT cannot adequately maintain the reliable transportation system Michigan’s economy needs or provide the level of service the public expects. Click to Continue

Priority 1-Orange Route Provide maintenance service as appropriate under prevailing weather conditions, with a goal of providing a pavement surface over its entire width generally bare of ice and snow.  Use OT during and after storm event until goal is met

Orange Route Statistics 34% of state highway miles 81% of commercial vehicle miles 70% of passenger vehicle miles 93% of state’s population live within 10 miles 95% of state’s employment base is within 10 miles

Priority 2-Blue Route Provide maintenance service as appropriate under prevailing weather conditions, with a goal of providing a pavement surface generally bare of ice and snow wide enough for one-wheel track in each direction.  Use OT during and after storm event until goal is met  Clearing the full width should be done after the storm event without using OT

Generally Bare of Ice and Snow The travel lane surface is free from drifts, snow ridges, and as much ice and snow pack as practical This does not mean bare pavement or dry pavement Motorists should expect some inconvenience and must drive responsibly

Communication and Coordination Communicate early (preseason) with neighboring agencies  Discuss winter operations practices  Coordinate shift times if feasible  Exchange contact information Communication during storm  Coordinate winter operations along a corridor  Minimize LOS inconsistencies at jurisdictional boundaries

Effort During Storm Plow and provide surface treatments as required during storm events Remove as much snow mechanically as possible Use only enough deicing agents as necessary Refer to the Salt Application Charts

Exceptions to Guidelines Some exceptions may be appropriate including:  Adjusting service levels due to storm severity and duration  Adjusting maintenance activities due to an abnormal influx of traffic (sporting event or festival)
