This file is a dump of the different lane identifiers and the various lane descriptions that they
have in the highways data.

This helps to give us an overview of the different lane types.

The number next to the lane descriptions is a count of how many times the description shows up
in the data, with the associated lane type. This helps to understand which lane descriptions
are most often used with the lane identifier.
