Traffic Environments

Tunnels, garages, toll stations and open roads are application environments that impose highly specialised and stringent requirements on Intercom solutions.


Intercom 2.0 Solution

Traffic noise

16 kHz signal technology – see “Speech”
High-definition audio signal makes voice clearly distinguishable from background noise.

Connection interference, interruptions
(e.g. in tunnels, garages)

Dedicated high-quality components
Off-the-shelf equipment is insufficient Multi-level fail-safety concepts e.g. Distributed Card Intelligence – see “Redundancy”.

High-volume call handling (e.g., public transport facilities at peak times)

Intelligent call handling
Dynamic call management, e.g. with call buffering, which supports staff co-ordination and ensures that callers are never confronted with a busy signal.

Operators’ and help providers’ need for immediate assessment of distress situations

Full real-time video/CCTV support
Enhances audio-only communication to make it more personal and immediate; also provides valuable visual feedback to helpers and security staff.

Weather, corrosion, vandalism

Sturdy, water-/weatherproof and vandal-resistant design
All outdoor components (call stations, loudspeakers, etc.) are protected against ambient influences.

Public address functionality and facility management
(e.g., signage, lifts, gates, etc.)

Open system structure
that integrates smoothly with third-party PA systems, building/facility management systems (Building Management System), etc. This is complemented by special features, e.g. the transmission of public announcements to motorists’ car radios in high-noise environments such as tunnels or parking garages (see ‘traffic noise’ challenge above).

Central control of multiple facilities

Centralisation support
enables full monitoring and control of all linked facilities and equipment from a central control desk.

Support of advertising and user information

Advanced technologies
E.g., automated/scheduled playback of pre-recorded promotional or informational messages at call stations; transmission of customer/passenger information via induction loop amplifiers, etc.

Economic efficiency

Evergreen Engineering philosophy
Stands for an extended product lifecycle, resource-saving product design, and long-term system backward compatibility.
