PC*MILER Routing Types
Hazardous Material Route Types &
Road Categories
PC*MILER Navigator calculates routes for hazardous materials
based on over thirty different road categories. The table below
and on the next page shows how each PC*MILER hazmat route
type handles each hazmat road category.
Favor = routing will prefer these segments
Avoid = routing will go around these segments whenever
possible
No Change = routing will not be altered in any way
Discourage = a lesser degree of avoidance, used when a state
or road authority allows hazmat only at certain times of day, with
prior notification, by permit, or in limited quantities, and for tunnels
not otherwise classified.
