AN Alicante firm has developed a system that allows pedestrians to hear the approach of electronic vehicles, something that has been highlighted as a danger as they increase in popularity.
Although manufacturers have incorporated some sound into the nearly silent engines, in urban areas where there is background noise this is often drowned out.
Alicante developers CHM, along with the University of Alicante, have developed a new asphalt called Fonoseguro that produces a rolling sound as electric vehicles drive on it. The project has been backed by the European Development Fund to address the issue which has been flagged by road safety experts.
It is particularly important for the safety of blind and visually impaired pedestrians and is intended for use in areas with a speed limit of 50 km/h or less.
