Tunnels Signalling & Equipements

Ensuring safety in these tunnels is a major issue for their operators and, naturally, for the road users who travel through them. The accidents that have occurred in the past provide evidence of this. The strict constraints that are imposed in tunnel environments have enabled TTS to emerge as a major and highly-regarded player in this specialist field.

Many years of experience, Acknowledged expertise

Tunnel equipment requirements vary widely. The know-how that TTS can call upon allows it to offer a variety of product ranges, including dynamic police signs, variable message and matrix signs, lane assignment signs, R24 stop signs, back-lit police signs, lane-change barriers, Information, guidance and warning panels etc. plus more specific innovative equipment such as guidance chevrons towards emergency exits.

Since 1999 our ability to offer products and services which meet your needs, our reactivity and our flexibility has meant that many partners in the ‘‘Solutions installation‘‘ sector turn to us to equip an ever-increasing number of tunnels, some of the most notable of which are :

Emergy exit lighting equipments

The covering of emergency exits in tunnels meets the imperative need to make emergency exits visible and immediately recognizable without hesitation, even when evacuation from the tunnel is not necessary, in order to participate in user education using the tunnels. This helps car drivers to reach the exit by themselves in case of an accident.
 

Efficient emergency exit signaling:

In case of an accident, particularly a fire, it is essential that users can easily locate emergency exits and understand their usefulness. To achieve this objective, it is necessary to install a lighting device permanently signaling the presence of an emergency exit. In a normal situation, this device complements the CE30 sign installed above the exit, as well as the pre-signaling of the location and distance of the exits. In the event of an evacuation, the dynamic equipment switches to flash mode, with highly visible flashing lights on either side of the door capable of piercing thick smoke to guide users to the nearest emergency exit.

We have flashing lights incorporating the automatic synchronization function. The vertical cowlings can be equipped either with green rectangular polycarbonate faces backlit with LEDs, or with green LED lights.

Tailor-made security:

Emergency light covers are fully integrated into our range of equipment dedicated to securing tunnels. This product equips many tunnels.
Defined as a regulatory tunnel standard, our emergency light covers can be adapted according to specific requests, or installation constraints.

GUIDANCE CHEVRONS

In order to help improve road users ability to identify safety exits in normal use and especially in order to help in finding these exits in evacuation situations, the use of guide chevrons installed alongside each exit has been validated. These emit an illuminated dynamic signal which guides users towards the nearest exit.
 

 

Behavioural aspects :

hevrons are symbols which are recognised by road users, and are used as safety and directional sign.They help 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 the evacuation of 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.).



The benchmark product :

TTS has manufactured the very first batches of equipment after being awarded the contract for making the prototypes. These were used to define and to undertake qualification of these new guidance systems in order that they might be universally installed in tunnels. As a result we have equipped all the road tunnels in the Paris region (DIRIF),
our recognised reference in this field.

R24 stop signs

Controlled Restrictions:

The R24 stop sign is designed to temporarily stop all road traffic in front of an obstacle or specific hazard.
Made of a 300 mm diameter flashing red light, TTS offers two housings as standard: stove-enamelled aluminium housing or a round plastic dome.


 

Non-illuminated signs

Effective sign systems:

Road users must be able to identify emergency exits and not confuse them with safety recesses, thanks to the use of specially designed signs. These signs must provide road users with means of communication, enabling them to be reassured in the event of an emergency or providing them with information, depending on where they are.
From the approved design right up to manufacture, TTS can offer you services based on its full range of signs and adhesive strips which use light reflecting films Class 1, Class 2 (HIP), Class 3 (DG) or photo-luminescent coatings.
