VAS are activated when an approaching vehicle is travelling over the system’s pre-set threshold. They display the speed with either an instruction to slow down or a sad face in red. A happy face or thank you is shown in green for drivers travelling within the speed limits.
Most of the VAS are fixed to existing light columns while some are solar powered. The signs are Conformité Européene (CE)-marked for quality and safety and are built with the latest Swarco LEDs, which are said to provide optical output for increased reliability as well as reduced power consumption.
Chhaganlal J Dabhi, project engineer for Brent Council’s Highways and Infrastructure Service, said: “One of the most common causes of accidents involving P2Ws is high speeds. And high speeds can cause severe injuries and fatalities, particularly for a motorbike rider who is the most exposed and vulnerable. However, we also know that one of the most effective measures to reduce accidents can be to inform all road users of the hazards and prevailing dangers, and advise them accordingly.”
