Dear Rony,
The main hurdle in this concept is to develop a proper radio system that has directional accuracy without being too expensive for the comman man.

I am not an expert but.... Wouldn't it be logistically simpler to work with GPS? Car based receivers seem to be able to locate, direct and speak. The only hurdle then is to have good map data which any such system would require in any case.
This system would be a local setup and need not be linked to a map. GPS may not give information of foot bridges, subways and other local structures.
Regards,
Rony.
