58 Saia®PCD2 and Saia®PCD3 substations with touch-screens, 1440 digital inputs and outputs and 270 analogue inputs are linked together by a redundant ethernet network.
This Saia®PCD network controls the following processes:
– Data collection about dangerous traffic situations
– Control of event-oriented traffic scenarios
– Control of traffic barriers independently of traffic scenario
– Data collection for traffic information (number of vehicles, lane occupation…)
– Data collection for air quality parameters (NOx, CO2, air purity, …)
This project was realized by Carboautomatyka, a Polish system integrator specializing in tunnel projects. The tunnel has been open to traffic for nearly one year.
