Ambulances in the Swedish capital are testing a KTH - made system ( 2013 ) that interrupts car radios with a warning message when they are responding to a nearby crisis . The experiment addresses the fact that some drivers may not hear emergency calls and therefore fail to respond to their presence quickly enough . But the experiment has also raised concerns that drivers on unaffected streets may also receive a warning . This , which will be tested on handful of ambulances in Sweden , will be trialled in Q1 of this year .
Ambulances in the Swedish capital are testing a KTH-made system (EVAM) that interrupts car radios with a warning message when they are responding to a nearby crisis. The experiment addresses the fact that some drivers may not hear emergency vehicles and therefore fail to respond to their presence quickly enough. But the trial has also raised concerns that drivers on unaffected streets will also receive a warning. EVAM, which will be tested on handful of ambulances in Stockholm, will be trialled in Q1 of this year.
