Does anyone have or has anyone tried a system of emergency vehicle detection and priority at signalled junctions=3F Our local hospital is currently being redeveloped and as part of this, a nu= mber of new signalised junction are to be installed at the accesses to the site= and I feel such a system would be very beneficial. I have seen some examples in= the states where they use sound or light devices to detect the sirens of emerge= ncy vehicles and give them priority through the signals and would like to know= if such a system has been tried in this country.
