A new traffic safety system installed on The Dartford Crossing, the busiest estuarial crossing in the UK, is benefitting from a high quality public address (PA) system to communicate with drivers in the event of an incident.
To combat the noisy road and traffic conditions,8431 PEL Services installed a 311 Bosch Praesideo digital PA system, with master and slave network-controllers and incorporating ambient noise sensing to automatically adjust sound levels to compensate for substantial variations in the levels of background traffic noise. The system has been set to maintain the sound level at 5dB above ambient levels, in real time, to ensure announcements are audible but not anti-socially loud.
Twelve Bosch LBC 3432-03 unidirectional projection speakers have been used with Praesideo at four locations; three speakers on each pole, at different heights to cater for the varying vehicle heights. The speakers have been configured in a contingent redundant arrangement, as an additional fail-safe. There are three amplifiers for each location including one on standby and the entire system is connected to an uninterrupted power supply.
