Othrys Tunnel

The Challenge

The Othrys Tunnel, part of the E65 motorway in Greece, faced significant challenges due to the need for a comprehensive traffic management system in a newly constructed infrastructure. It is the longest road tunnel of the whole motorway and it is one of the longest in Greece. Ensuring traffic safety, efficient mobility, and seamless integration with existing systems was crucial for the tunnel that cuts through the Othrys mountain range, bypassing the challenging terrain to improve connectivity.

Greek road authority was looking for:

  • A state-of-the-art traffic analysis and incident detection system to monitor and manage the newly constructed tunnel effectively.
  • The AID system equipped with a graphical interface for real-time event notifications and performance management

The solution

The Othrys Tunnel is an integral component of the E65 motorway, also known as the Central Greece Motorway (A3), which spans 230 km to enhance connectivity between Northern and Southern Greece. This strategic infrastructure project, planned for decades, includes the Othrys Tunnel to bypass the mountainous terrain efficiently.

Sprinx, in collaboration with Systemica, implemented an advanced Automated Incident Detection (AID) and traffic analysis system using the traffix.ai platform. This system includes 88 high-definition cameras and server-side processing facilitated by three servers equipped with Nvidia cards. The traffix.ai system integrates seamlessly with the dragon platform, ensuring comprehensive monitoring and real-time event notification.

The solution’s deployment involved extensive camera coverage for real-time monitoring and rapid incident detection. The AID system enables the detection of critical traffic situations, such as stopped vehicles, congestion, pedestrians, and wrong-way drivers. It promptly alerts the operations centre, allowing for effective and efficient intervention, ensuring safety and facilitating smooth traffic flow in a strategically important area of the Hellenic territory.

The Result
  • Enhanced safety: the automated incident detection system provided real-time alerts for any traffic incidents, allowing for immediate response and reducing the risk of secondary accidents. This proactive approach has significantly increased the overall safety of the tunnel.
  • Improved traffic flow: by analyzing traffic patterns and congestion in real-time, the system facilitated smoother traffic flow and minimized bottlenecks. This optimization of traffic management has led to a more efficient transit experience for drivers.
  • Seamless integration: the integration with the dragon platform and other third-party systems ensured that the traffic management solutions were cohesive and fully operational, allowing for better data sharing and coordination across different platforms.
  • Real-time Alerts: thanks to the dragon platform and the Event Manager feature, control room operators can rely on immediate notifications supported by audible alarms.
