I have finished collecting coordinates for all of the VASCAR lines I can find in VA on interstate highways. I just sent this information to Cheetah for inclusion in the Trinity database.
Anyone using a C50 in VA can expect it to start alerting to VASCAR locations during the next month or so (1 or 2 database updates).
Please do not depend solely on C50 warnings, as I gathered this info on Google maps. Road construction and poor picture quality may cause some lines to be missed in google. If you find any that I missed, please send GPS coordinates to firstname.lastname@example.org
I would encourage anyone living in a state that uses airborne VASCAR to collect this data and report it to Cheetah. That way C50 users will be warned when entering these traps.
