all you need for a phone to receive radio frequency is an antenna, and in many cases, headphones plugged into the phone is all you need for that. if an app were to receive a frequency then turn it into a signal the LDW systems sees then it should be pretty simple.
edit- gps would be more efficient but you get the gist of it, whatever It, is.
edit.2- if Dominos can create a self driving delivery car, then i think this technology would be a simple feat.
airplanes do this now using ADS - they transmit their position so everyone can hear it (using GPS) - everyone that can hear it gets it directly,
others that can't, get it through a repeater (down to ground, up to satellite, back to plane) - that is 3 dimensions, and unrestricted turning,
and the alerts are very accurate - put it in 2D and limit it to roads. This "hive" mentality is what will eventually eliminate the ethical problem of
should a car kill/injure a pedestrian or occupant if the decision needs to be made, cause the car will know about the pedestrian way before it becomes a problem.
