Athens, Greece

The Elefensina-Stavros Motorway, located in Athens, Greece, is a Design, Build, Finance and Operate (DBFO) highway project undertaken by the Attiki Odos Construction Joint Venture. The Motorway is 65 km long with 35 tunnels, 38 interchanges, and 173 tolling lanes.

The ITTMS includes a full range of features: traffic monitoring, incident detection, surveillance (CCTV), motorist information through arterial advisory signing, and motorway signing and tunnel control features, including lane control and speed advisory signing. The ITTMS is being expanded to include management of all of the electronic elements of the highway, including the ventilation, lighting, pumping, fire detection in the tunnels and lighting and irrigation in the open road sections – a full Motorway Management System. The communications system provides full redundancy for the all data, voice and video supporting both analogue and digital communications. The entire system was delivered in logical stages, supporting the opening of various sections of the Motorway.
