Safety signage CHEVRONS

Chevrons are symbols which are recognised by road users and whose use as safety and directional signs is understood. They are therefore used to identify exits to road users under normal driving conditions, and act as reinforcement signage for the same exits when illuminated in scrolling/streaming animated mode. When in static mode the chevrons help point out emergency exits, help in identifying them, help to locate them and provide an estimate of distances to the exits. In the dynamic state the chevrons act as indicators showing the direction to follow for evacuation of the road users in the event of an incident in a tunnel. TTS chevrons are designed to comply in every detail with the technical requirements demanded by the strict constraints encountered in tunnel environments (protection indices, impact resistance, self-extinguishing properties, material toxicity, visibility, light levels, design ergonomics etc.).
