Hazardous Materials / Cargo (HM) (HC) on BGS
We have new interstate exit/entrance ramp signage being put up by Ohio DOT that includes the HM inside a circle to designate Hazardous Material routes (or the older HC for Hazardous Cargo). Not sure if I'm asking the right question, but an Update Request pointed out the HM symbol on the new Big Green Sign directing drivers carrying Hazardous Materials to the proper route.
Also, last year ODOT in Columbus lost a bridge to a fire from a truck carrying Hazardous Materials on a non-HM route. By marking it in WME from the BGS, it will read it out to drivers as well as display it if the driver checks the turn-by-turn instructions-list (not that that would force drivers to follow an HM route.)
One proposal would be, for instance, to mark an exit ramp (from US-33 freeway) as "Exit 108: I-270 S / HazMat Rte". I believe this reads back correctly in the app also.
I will admit this is a different approach than tying the HM-designation to a road-type, or road-feature like "Unpaved" or "Toll Road". These approaches may still be appropriate for HM, but if approved, using the Street description from the BGS can be implemented without changes to WME or the app.
Thoughts? Thanks, David
