Modeling the impact of the use of chemical anti-/deicing on the roadside environment requires knowledge of the roadside exposure to salt, the vulnerability or dose-response relationship of the modeled environmental subjects and, preferably, the “cost” of the following impacts. The results presented in this paper are the first tentative test runs of the environmental sub-model of the Swedish Winter model. The environmental cost will in this case study be the cost for vegetation damage larger than a chosen accepted level of damage, and a cost for groundwater protection installations. The total environmental cost in this small case study will roughly be between 1.5 and 2.5 MSEK.
