Yes and no. There’s been radio spectrum assigned for “smart roads” (or vehicle to infrastructure, V2I) for 20 years now.
Cadillac and Audi are the only ones with vehicles capable of doing DSRC now, if I recall correctly. The problem is—who wants to build all that smart infrastructure? Who wants to maintain it? Who will upgrade it after it’s obsolete?
My guess is that the way forward with automated cars lies in on-board processing intelligence with relatively minimal network required, and what is needed will largely be provided via commercial cellular or unlicensed (Wi-Fi) infrastructure.
