Customize Routes with Road Preferences
You can instruct PC Miler to either favor or avoid certain
roads when generating a route. To try this out, let’s create a new route from
Augusta, ME to Charleston, SC and then designate road preferences around
Augusta. Whole roads can be avoided or favored using the Custom Roads Manager
(Tools menu), but in the steps below we’ll be picking road segments from the
map.
-
Minimize any open windows, and click the New Route
button on the tool bar to open a new route entry window.

-
Enter “Augusta, ME” as the origin, “Oakland, NJ”
as a stop, and “Charleston, SC” as the destination of your route,
using any ZIP codes for those cities. Run the route.
-
In the Map menu, select Frame and uncheck Auto
Frame Route.
-
Highlight Augusta on the stop list and double-click to
zoom into this city in Maine on the map. Notice that PC Miler’s route
travels on I 95 (the Maine Turnpike) going south from US 202 out of
Augusta.

-
Click on the Favor Roads button on the tool bar,
then return to the map window.
-
Zoom into Augusta again if necessary, then click below
Hallowell on the segment of US 201, ME 27 that runs south out of
Augusta to designate it as a road to be favored. Green highlighting
will appear, indicating a favored road segment.
-
Now click on the Avoid Roads button on the tool
bar.

-
On the map, click on I 95 going south from US 202
to designate it as a road segment to be avoided. Red highlighting
will appear, indicating an avoided road.

-
Select Route 3 (the Augusta route) from the Windows menu,
click on the Options button and check Use Custom Roads, then
click OK. This step is crucial to running a new route that
includes the road preferences you’re about to designate. If this option
isn’t turned on, road preferences won’t be included in PC Miler’s route
calculations.
 -
You’ll see that PC Miler automatically reruns the route
using the new road preferences – your route now travels on US 201 and avoids
the Maine Turnpike!

HINT: To clear road preferences, you have two options:
you can click again on the selected road segments – with the appropriate button
selected (Avoid Roads or Favor Roads); or open Tools menu > Manage Custom
Roads and use the Avoids and Favors tabs to delete current
designations.
