Example .list file entries

Below are several example entries for a user's .list file.

Break up your travels by highway and region. By region, we usually mean a country, such as Spain or Germany. However, for large countries like the United States and Canada, further break your travels down by state or province as well. Then use the Highway Browser to look up the highway and waypoint labels.

Highway segment within a single region.
For the segment of I-80 between Exits 161 and 224 in Pennsylvania, USA, look up the highway and waypoint labels for those interchanges in the Highway Browser. The Highway Browser shows the highway as PA I-80 and lists the waypoints as 161 and 224. Enter the following line into your .list file:

PA I-80 161 224
Highway segment crossing into multiple regions.
To enter the segment of I-81 between Exit 300 in Virginia and Exit 10 in New York, break up the segment into smaller pieces by region. The Virginia segment begins at Exit 300 and ends at the West Virginia border, so use waypoints 300 and VA/WV for the Virginia segment. I-81 runs from border to border in West Virginia, Maryland, and Pennsylvania, so use waypoints WV/MD, MD/PA, and PA/NY for these states. The New York segment begins at the Pennsylvania border and ends at Exit 10, so use waypoints PA/NY and 10. All of these waypoints are listed in the Highway Browser.

Enter the following lines in your .list file for this whole segment:

VA I-81 300 VA/WV
WV I-81 VA/WV WV/MD
MD I-81 WV/MD MD/PA
PA I-81 MD/PA PA/NY
NY I-81 PA/NY 10
Beltways (full loop highways) within a single region.
In single-region beltways, a waypoint has been selected as both the highway's beginning and end. This location is used for both the first and last waypoints of the highway, with a different waypoint label for each end. If the segment you wish to enter into your .list file crosses that point, split your segment into two at that point.

Consider first the segment of the Baltimore Beltway (MD I-695) between Exits 17 and 31 along the northern side of Baltimore. I-695 begins and ends at a southern waypoint called both 0 and 48. Since the waypoints run continuously from 17 to 31 without crossing that southern point (compare to next example), treat this segment simply as beginning at waypoint 17 and ending at waypoint 31:

MD I-695 17 31

Now consider the southern segment of the Baltimore Beltway between the same Exits 17 and 31. The waypoints numbers reset in this range: 17, 16, ..., 1, 0, 48, 44, ..., 31. Waypoints 0 and 48 refer to the same point. With this in mind, treat your whole segment as two, one with ends at 0 and 17, and the other with ends at 31 and 48:

MD I-695 0 17
MD I-695 31 48

To enter the entire Baltimore Beltway, use the two labels for the common end points, which are the first and last labels shown in the Highway Browser:

MD I-695 0 48
Beltways crossing into multiple regions.
Treat segments along these beltways just as you would any other segment that crosses into multiple regions: one .list file line per region.
Concurrent (overlapping) highways.
Highways can overlap another highway so that the same highway has two or more concurrent numbers or names. Include separate lines in your .list file for each highway in overlaps.

For example, if you travelled all of I-84 in Pennsylvania, you also traveled on an overlapping piece of I-380. Include a line for each highway:

PA I-84 0 PA/NY
PA I-380 I-81 24

A mechanism is in place to automatically include concurrent highways. If you included the above section of I-84 in your .list file but did not include the concurrent section of I-380, I-380 will still be included for you. Presently this mechanism works well but occasionally misses a concurrent highway. It is recommended that you try to include concurrent highways manually.
