PC*MILER Routing Types
PC*MILER Routing Types
National Network routing stays on the National Network to the
maximum extent possible. Given that many areas are not
directly served by the National Network, the origin and stop-offs
of your route may not be on the National Network. In these cases
PC*Miler will take the shortest reasonable path from the origin
and stop-offs to the Network. Detailed Route Reports
(driving directions) for PC*MILER National Network routes provide
a warning wherever the route is forced to use a non-conforming
link. These road segments should be checked before traveling,
National Network mileage tends to be higher than Shortest or
Practical mileage.
These designated highways permit, at a minimum, 102” wide,
single 48 ft. trailers and 28 ft. double trailers. The interstate system
and most, but not all, remaining designated routes are open to
80,000 pound vehicles. Certain states, notably Arkansas and
Mississippi, have designated certain National Network segments
with less than an 80,000 pound capacity.
In addition to the national Network highways, access routes and
access policies are components of routing STAA dimensioned
trucks. The Federal government has mandated that no state may
prohibit travel from the National Network for a minimum of one
road mile unless safety restrictions apply. Additionally, no state may
deny reasonable access to terminals and facilities for food, fuel,
repairs, and rest.
