Like many other electric vehicles the Volvo buses, which already carry passengers in some cities in Europe, completely silent. And the Swedish automaker wants to give them a little "voice". The idea is to give buses the opportunity to break the silence, signaling road hazards, in particular, to warn of its approach to pedestrians and cyclists.
A new system of detection of pedestrians and cyclists from the Volvo uses a camera to constantly monitor what is going on around the bus. If the system detects someone nearby, it emits a short beep to warn about the approaching bus. The system also uses audio and visual signals to alert the driver of nearby people — in any case, if the driver suddenly fell asleep at the wheel. If, in the opinion of the system, the collision is inevitable, it beeps very loudly.

Despite all the "noisy" innovations, Volvo promises that the buses will remain quieter on public transport than buses running on gasoline. According to the Director of Volvo Peter Danielsson, the sounds of the new signal system will not irritate residents — they will be quieter than low frequency noise produced by conventional buses and will not penetrate through Windows with triple glazing.
The detection system will work on the Volvo buses in Europe in 2017.
