When people tell you not to play music at full blast in your car, they're not necessarily raining on your parade -- there's a real concern that you might not hear an emergency vehicle until the last moment. You might not have to worry quite so much if a Swedish experiment proves successful, though. Ambulances in Stockholm are testing a KTH-made system (EVAM) that interrupts in-car audio with a voice warning when they're close by and responding to a crisis. The only requirement is that your car's FM tuner support the Radio Data System format, which is common in the cars you see on the road. The interruptions are speed-sensitive, too, so you'll get notices at greater distances when you're on the highway.
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 .
