7 years ago we might need to check on whether one of these values is available in the original file:
currently using 'R' at https://github.com/MetropolitanTransportationCommission/caltrans-typical-weekday-counts/blob/get-xy/Consume/get_xy.R#L83
If a postmile prefix letter is needed, it will be one of the following letters:
- C — Commercial Lanes
- D — Duplicate postmile at meandering county line
- G — Reposting of duplicate postmile at route end
- H — Realignment of D Mileage
- L — Overlap postmile
- M — Realignment of R mileage
- N — Realignment of M mileage
- R — First realignment
- S — Spur
- T — Temporary connection
they may have been dropped in this script since it was a summary, but we need them now to get x/y's.
otherwise, it seems like the output of that script has only ~80 unique locations.
