Greece, under the frame of the C-Roads Platform initiative, participates as a member state with its national pilot since June 2019. The Greek pilot takes place at two test sites, one in Northern Greece (Egnatia Odos Tollway Pilot) and one in Attica Region (Attica Tollway Pilot), and its main objective is to conduct a specific set of Day 1 and Day 1.5 C-ITS services by using a balanced mixture of ETSI ITS G5 and cellular communication technologies.

A breakdown of the selected Day 1 C-ITS services of the Greek pilot contains:

  • Road works warning with special focus on lane closure and other restrictions
  • Hazardous locations notification which includes the cases of a stationary vehicle, weather condition warning and obstacle on the road
  • The in vehicle signage (which applies to the equipped ones embedded with such technology) where variables message signs of “free text” as well as speed advice messages to avoid the shockwave damping effect are sent to vehicles by the road operators
  • Probe vehicle data in regards to cam aggregation. Lastly, the Greek Pilot has also selected from the Day 1.5 C-ITS services Smart Routing

Particularly, the above services will be inclusively achieved per case through the two aforementioned test sites. In Northern Greece test site, 30 km of the motorway named “Egnatia Odos” with specific attributes such as geometry, traffic volumes, rural environment, mountainous area, successive tunnels and bridges will be examined and 25 roadside access points (Road Side Units – RSUs) plus one mobile will be installed. RSUs will enable the communication and the ITS messages transfer between vehicles and road infrastructure. In Attica region, 20 km of the road section of Attica Tollway (central sector) within the same prefecture will be examined and 10 roadside access points plus one mobile will be installed.

Currently, the design of the Greek test sites has been completed. C-ITS services to be deployed have also been specified while the necessary procurement process has been initiated. The Attica Tollway test site has already identified the supplier while the other one, Egnatia Odos, is in the process. Finally, the first set of services for the Greek pilot have been launched and validated.

Greece is fully committed to contributing to the C-Roads Platform and be aligned with its results. The ultimate goal is to pave the way and contribute for large-scale deployment of interoperable C-ITS services in Greece.
