Attiki Odos Motorway
Challenges
- Complex infrastructure scale - Needed to centralize monitoring/control of 60km motorway with 32 interchanges, hundreds of overpasses, and multiple tunnel systems.
- Critical deadline pressure - System had to be designed, integrated, and operational on time for the 2004 Summer Olympics in Greece with no room for delays.
- Massive I/O requirements - Required real-time interface with 25,000+ I/O points across lighting, ventilation, fire systems, power, and emergency equipment.
Outcomes
- Centralized emergency response - Fast, reliable control center gives operators complete visibility of entire highway for quick incident detection and emergency handling.
- Sub-2-second response time - Redundant servers interface in real-time with controllers over Ethernet, ensuring immediate air quality monitoring and tunnel ventilation.
- World-class motorway status - On-time deployment created one of Europe's most modern motorways with comprehensive electromechanical system monitoring and control.
“This monitoring and control application was designed and integrated on time by Algosystems SA in Athens, Greece. The SCADA graphics are very impressive, and the system allows our operators a complete picture anywhere on the highway. The system provides a fast and reliable centralized tool for our emergency personnel and support team. GENESIS software helps make the Attiki Odos a world-class motorway.”
About Attiki Odos Motorway
The Attiki Odos Motorway is one of the most modern motorways in Europe. The highest standards have been observed in its design. The motorway extends over 60 km, is four lanes wide, and has 32 multi-level interchanges and hundreds of overpasses. The Attiki Odos uses the most modern equipment for incident detection and emergency response.
Solutions Deployed
GENESIS™ is used in a redundant configuration along with AlarmWorX™ alarm management. The redundant GENESIS servers are responsible for the monitoring and control of all electromechanical equipment for the tunnels and highways.
This includes the lighting and tunnel ventilation systems. The air quality within the tunnels is monitored, and GENESIS can allow exterior airflow, as needed, to keep the tunnels clear of carbon dioxide, smoke and nitrogen oxide.

Key Features
In addition to controlling the lights and ventilation system for all the tunnels, GENESIS software is also responsible for other systems within the Attiki Odos Motorway.
All emergency fire hose panels, irrigation pumps, power distribution (medium and high voltage), UPS systems and diesel generators are monitored and controlled by GENESIS. MSDE is used for all data logging.

Project Summary
Mitsubishi Electric Iconics Digital Solutions’ GENESIS software system was installed at Attiki Odos to centralize motorway operations and provide the status of all electromechanical systems. The SCADA system enhances the ability of motorway operators to easily identify and handle emergency situations and overcome malfunctions of equipment in order to provide better quality of services.
With over 25,000 I/O points, the redundant GENESIS servers are interfacing in real time with Opto22 LCM4 redundant controllers and LCSX-Plus controllers over an Ethernet network. The system response time is less than two seconds. GenBroker is used to enhance communication of operator workstations with servers. Algosystems, using Mitsubishi Electric Iconics Digital Solutions OPC ToolWorX™, developed a multi-threaded OPC server with redundancy features to interface with Opto22 controllers.

Benefits of the System
Mitsubishi Electric Iconics Digital Solutions software was selected for this application due to the open modular architecture of GENESIS along with the proven reliability of the redundant GENESIS servers and the breadth of OPC servers and toolsets.
