Smart Systems

Innovation for more road safety

Olympia Odos motorway is continuously upgraded with the latest technology.

In addition to infrastructure projects, we focus particularly on innovations that help prevent dangerous incidents and accidents. We have summarized the main smart solutions we are implementing for safety on the motorway:

Adaptive Road Lighting

Olympia Odos is the only highway that has installed a fully dynamic Adaptive Lighting system to ensure the ideal level of illumination at all times.

The system leverages Big Data, AI, and machine learning, continuously analyzing real-time traffic data to dynamically adjust lighting levels based on actual conditions on the highway. Continuous traffic monitoring at each junction allows the system to calculate overall traffic on the highway and make predictions for the next hour.

Thus, in cases of reduced traffic, lighting is automatically dimmed to maximize energy savings, while in the event of heavy traffic, incidents, or adverse weather conditions, the system commands the automatically increase of the lighting level.

In particular, real-time data is used regarding:

The traffic
The weather conditions affecting the visibility
Events captured by artificial intelligence cameras in order to immediately identify potential hazards.

The combination of LED bulbs and the full installation of the adaptive lighting system achieves an average annual nighttime energy consumption reduction of over 70% compared to conventional sodium lighting.

In addition, greater safety for drivers is ensured, as the data collected support not only the lighting system but also the detection of incidents such as vehicles moving in the wrong direction, pedestrians, or animals, operating continuously 24/7, both day and night.

Road lighting poles

Within the context of ensuring the safety of the motorway, Olympia Odos was started the structural assessment of 1,150 road lighting poles on Elefsina - Korinthos section and of 50 poles on Korinthos-Patras section, at Rion I/C. This specific area has been selected because of the strong winds that prevail in the area.

The structural assessment has been conducted by using a non-invasive system which thoroughly examines every pole separately and produces a detailed report regarding the condition of each pole. Approximately 1% of the poles of the Project will be replaced.

SMART TUNNEL

The Smart Tunnel project of Olympia Odos pertains to the development of a comprehensive system to monitor and assess the tunnels of the Motorway, based on the most modern methodologies and technological tools.

The Infrastructure Management System provides real-time data on the condition of the equipment which can be used to early detect defects and ensure their faster making up. At the same time, the analysis of this data provides us with the necessary information for planning the next maintenance campaign, ensuring savings from the heavy maintenance of the infrastructure, a more appropriate maintenance and an increased the life cycle of the equipment. This system ensures the safety not only of the users, but also of the motorway employees, as potential defects are detected in time and dealt with in a targeted and effective manner, without the need for additional dangerous diagnostic tests on the field.

The Smart Tunnel system was installed, to be tested, in 2019 in the 700m long "Girokomio" tunnel of Patras Bypass, while in 2021 it was decided to extend it to the four (4) larger tunnels and six (6) buildings of Patras Bypass.

MIRANDA

Olympia Odos disposes of an innovative diagnosis and recording tool called MIRANDA, specializing in monitoring and recording possible defects on the pavement. The tool is implemented in cooperation with the French Institute of Science and Technology for Transport, Development and Networks IFSTTAR. It uses the motion sensors (accelerometers) of mobile phones to record the settlements in association with the mobile phone’s GPS to record the location of the findings.

Thanks to this tool, we timely assess the structural integrity of the pavement and the underlying layers. Moreover, it minimizes the frequency of using other measurement tools that would require a larger mobilization and would affect the traffic and the safety along the motorway.

LED lighting

An essential initiative for safety and energy conservation on Olympia Odos is the modernization of the lighting system, which involves the replacement of conventional light bulbs with high-efficiency LED lights along the motorway's entire length, including within tunnels and lane covers. Upon completion of this project, Olympia Odos has become a fully "LED-illuminated motorway," achieving energy savings of up to 75% while optimizing lighting quality and safety for drivers, users, and motorway personnel.

At the same time, all the luminaires are connected to a new smart control system (DALI), which allows for the independent management of each luminaire and offers full dimming capability.

As part of the same project, the interior of the tunnels was recoated with an innovative, highly reflective, photocatalytic coating (Vitex FOS). This technology enhances light diffusion within the tunnels, facilitates the removal of organic and inorganic pollutants, and neutralizes pathogenic microorganisms, thereby improving air quality.

Como App

In an ongoing effort of transitioning to digital transformation, Olympia Odos has developed a new innovative software called Como App to monitor the construction/maintenance works in terms of Quality, and Health & Safety in the field. This application allows each works Inspection Supervisor to fill in on-site and instantly submit evaluation forms, including photos and comments, in order to identify any risks and failures in a timely manner, thus helping to increase safety levels.

Sensors

A new measure being tested by Olympia Odos to enhance the protection of workers and visitors at the worksite, pertains to the installation of a sensor on a vehicle used at the worksite, along with tags worn by workers/visitors who are in the same area.

If someone is dangerously close to the moving vehicle, the system immediately alerts the driver allowing him to act in time to avoid the risk of an accident.
