ogr2osm converts the FDOT file just fine. It also loads up without
trouble into qgis.
But the road IDs are not very useful. Alligator Alley is 03175000,
which is not a FIHS number, or a Tiger:tlid You have to get the
localname.shp file to get more interesting names like:
NAME ALLIGATOR ALLEY,I-75
If your goal is to match to the osm data automatically it would take
Merge localname.shp and maxspeed.shp so you have both the speed and
the roadway number.
Using xapi, load all data for highway=motorway in the bounding box
Conflate the two by name search.
The maxspeed data is also missing various roads (there are islands or
roadway that connect to nothing), and it has 0mph speed limits.
