Description

When travelling at low speeds, electric and hybrid buses are almost silent. This factor increases the risk of incidents with pedestrians and other road users. The visually impaired in particular usually rely on audible environmental cues to assist with their mobility and orientation.

As part of the V-Series range of electronic products to enhance the safety of buses and coaches, Forman’s V-AVAS is designed to warn road users of approaching electric and hybrid buses.

This acoustic vehicle alerting system emulates the sound of a traditional bus powered by an internal combustion engine, providing distinct indications of the vehicle’s location, direction and speed. The distinct Transport for London (TfL) sound is the result of extensive research and testing and can only be heard in the vehicle’s quiet range of 0 to 30km/h, minimising the impact on people in the surrounding areas.

 

UNECE Regulation No. 138

The Forman V-AVAS hardware and sound are compliant with Regulation No. 138 of the Economic Commission for Europe of the United Nations (UNECE) – Uniform provisions concerning the approval of Quiet Road Transport Vehicles with regard to their reduced audibility. In line with this regulation, all manufacturers must install an AVAS system in new types of quiet electric and hybrid electric vehicles from 1 July 2019, and to all new quiet electric and hybrid vehicles registered from July 2021.
