For this system to be practical at all, the antennas would need to be placed well ahead of the intersection or exit/entrance ramp, in order to allow drivers time to get the message and safely prepare to turn. So not at every intersection, for every intersection. Multiple times for all the directions of traffic that would need to use it.
