to achieve After-event LOS a PSIC of 2 or 1 Low >8.0 Medium 3.1–8.0 High <3.1 STRATEGIES AND LEVEL OF SERVICE Table 7 shows the expected LOS levels that can be achieved within- and after-winter weather events from various snow and ice control strategies and from tactics. For convenience, each strategy/tactic is described again below.
