Traffic Control

Husovicky Tunnel in Brno, Czech Republic Husovicky tunnel was built in 1999 with the objective to ease traffic congestion between the east and north districts of the city Brno in Czech Republic. It is approximately 600 meters (0.4 miles) long. Thousands of cars pass through every day. In order to enhance the safety in the tunnel and make the tunnel maintenance more efficient the previous obsolete automation system monitoring traffic signs, lights and ventilation was replaced by a new automation technology in 2012.

The new control system is based on progressive modular system of ControLogix PLCs and mySCADA Box following the latest trends in automation in performance and security. All visualizations are made in mySCADA Editor and deployed to PCs in the control rooms as well as to iPads that are used as local operators‘ touch panels. The operators can retrieve online system data in the control room as well as in the field. The authorized operators can change the alarm activation values, alarm description, severity, action mode and notice delivery (SMS, e-mail). All history data are logged with 1-second precision in mySCADA Box and available on request anytime, so that the operators have a full control over all events and alarms.

With the remote access the system can be accessed 24/7 from anywhere while ensuring system safety.



The deployment of mySCADA application offered the ideal solution for the customer. The advanced visualization of the tunnel technology gives a perfect and user-friendly overview of the entire system. The operators can easily monitor the lights, ventilators and traffic signs, rapidly detect any system failure and – if requested – change the system parameters. The maintenance personnel can take advantage of unlimited mobility and operate the technology in field with the mobile iPads. Running the application on the iPads fully replaced obsolete HMI panels in the control room. The system is shared with police and fire brigades who on-line monitor the tunnel directly in their own control rooms. The customer gained significant acquisition price savings as the mySCADA system price is a fraction of the price of the competition systems.

The synergy of ControLogix and mySCADA presents a very innovative and powerful SCADA solution to provide for maximum security, smooth traffic flow and constant system overview.
