Maintenance accountability process
The Maintenance Accountability Process (MAP) is a tool which measures and communicates the outcomes of the maintenance activities. It provides the tools to link strategic planning, the budget and maintenance service delivery.
WSDOT's work results are measured, recorded and compared to the MAP criteria to determine the level of service (LOS) delivered.

MAP level of service
We report LOS on a scale of “A” through “F.” The general definition of each LOS is as follows:
LOS “A” – This is a very high service level in which the roadway and associated features are in excellent condition. All systems are operational and users experience no delays.
LOS “B” – This is a high maintenance service level in which the roadway and associated features are in good condition. All systems are operational. Users may experience occasional delays.
LOS “C” – This is a medium maintenance service level in which the roadway and associated features are in fair condition. Systems may occasionally be inoperable and not available to users. Users may experience short term delays during repairs but the delays are not be excessive.
LOS “D” – This is a low maintenance service level in which the roadway and associated features are in generally poor condition. Systems failures occur because it is impossible to react in a timely manner to all problems. Occasionally delays may be significant.
LOS “F” – This is a very low service level in which the roadway and associated features are in poor and failing condition. A backlog of systems failures would occur because it is impossible to react promptly to all problems. Significant delays occur regularly.
Slow down on ice and snow.
It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.
Carry chains, practice installing them.
Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.
Pack your winter car kit.
Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
