types, the Heavy and Light Vehicle routing option is also a critical setting. A “heavy ve-
hicle” is one weighing at least 80,000 pounds; a “light vehicle” weighs less than 80,000
pounds.
When Override Restrictions is left unchecked, Heavy Vehicle routing will be in effect,
so both truck-prohibited and truck-restricted roads will always be avoided. In addition,
Heavy Vehicle routing takes nationwide 13’ 6” height restrictions into account.
Override Restrictions is part of the standard routing profile setup.
Toll Roads Routing: If Avoid If Possible is checked, PC*MILER Navigator will avoid
long stretches of toll roads but won’t take long, impractical detours, to avoid toll
bridges and tunnels. Example: a trip from Boston, MA to Albany, NY avoids the Massa-
chusetts Turnpike, but a trip from Camden, NJ to Philadelphia, PA includes a toll bridge.
International Borders Open Routing: If this option is checked, the calculated trip
will ignore international boundaries (Canada and Mexico) when necessary to generate
the best route. If this option is not checked the calculated trip will never cross interna-
tional boundaries. For example, if all your stops are in the United States, the route will
stay in the U.S. even though the most practical or shortest route would involve some
Canadian mileage.
Hazmat Routing: PC*MILER Navigator calculates routes for hazardous materials
based on over thirty different road categories. Hazmat route options include: General,
Caustic, Explosives, Flammable, Inhalants, and Radioactive. To calculate normal (non-
hazmat) PC*MILER routes, select None. The table in Appendix B on the next two pages
shows how each PC*MILER hazmat route type handles each hazmat road category.
Hazardous Material Route Types & Road Categories: The 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 al-
lows hazmat only at certain times of day, with prior notification, by permit, or in limited
quantities, and for tunnels not otherwise classified.
