Electronic vehicles (EVs) are a technical marvel – but vulnerable road users (VRUs) can’t hear them, which creates obvious safety problems.


4065 Brigade Electronics says help is at hand with its Quiet Vehicle Sounder (QVS), a speaker system which the company says reduces collisions between pedestrians and hybrids and EVs.  

The QVS, also known as an acoustic vehicle alerting system, simulates the sound characteristics of an internal combustion engine by emitting a blend of bbs-tek white sound frequencies that are used in vehicle reversing alarms.

According to Brigade, the solution changes pitch according to the speed of the vehicle and produces a sound that a VRU can identify as a vehicle.

The QVS can be retrofitted to most commercial vehicles and works from a 12 or 24 volt power source to avoid draining the power of a hybrid vehicle or EV, the company adds.

At least not according to the OECD 2013 report Cycling, Health and Safety which contains the statement: ‘Cyclists are often forgotten in the design of the road traffic system’. Looking through the statistics that exist (each country appears to compile them differently) it is not difficult to see how such a conclusion cou

The future looked bleak as the city and greater urban area bled jobs and population. It was on 18 July 2013 that Motown, as Detroit is also known, filed for Chapter 9 bankruptcy protection, the
