Repurposed/reused Android smartphones with ~$50 in solar panel and mounting
would do it.  Pulling the phones from their cases and putting them in NEMA
enclosures might take care of the theft problem, and a flexible mounting
and replaceable Lexan window would help with vandalism.

I suspect that, even though Android phones would have more features than
needed, custom-built devices would not cost any less.

My only worry is that Tri-Met would wind up paying through the nose for
data service (like the City of Portland did with the smart-meters).

(Yes, there are companies that provide cheap cellular data service for
industrial purposes.  No, I don't know how to make a deal with them.
Apparently, neither does the City.)

Heck, could probably pull it off for about as much as a "talking bus"...
