Providing mission-critical and professional audio solutions to modern transportation companies is a complex undertaking. Bus stations, subway, regional railways – all demand flexible, secure, and mostly reliable solutions for delivering announcements, music, and emergency calls directed to specific areas. Nationwide, a railway network may count hundreds of stations supported by dozens of audio servers. Of course, such an architecture incorporates an array of different voice announcement systems and the sensitive priority rules system for messaging.
THE NEED
Heavy-weight – often public – transportation operators team up with expert systems integrators to engineer extensive audio systems that meet a series of stringent requirements. Among their basic requirements, interoperability with management applications is critical as is the ability to deliver specific notifications and emergency messages in a timely and targeted manner, according to both schedule and message priority. While the many zones involved may cover a countrywide geographic area, the retained solution must enable centralized control. It should also feature monitoring and reporting capabilities that help to ensure uptime across all zones.
THE CHALLENGE
Utmost reliability and steady performance of these systems are paramount as they involve public security and safety. Therefore, the integrator’s sturdiness in terms of technology, production, testing and quality clearances will be scrutinized. Additionally, the chosen system has to demonstrate that it relies on a spotless track record of use cases implemented at a similar scale.
