Patrolling air quality on one of Europe’s greatest motorways
The Egnatia Motorway traces its origins back to Roman times and remains a vital link between Greece and the rest of Europe. Funded by the European Union the Environmental Highway Observatory uses one fixed and one mobile AQM 60 compact air quality station to monitor and manage the impact of the highway on the surrounding environment.

The origins of the Egnatia motorway trace back to the Via Egnatia built by the Romans between 146 and 120 BC to connect Europe. Today it continues to be vital infrastructure driving economic development in Greece as well as between Western and Eastern Europe. Egnatia Odos S.A. is the company ensuring the construction, maintenance and operation of the Egnatia motorway, one of the major road construction projects carried out in Greece and Europe.
Mobility is a key to quality of life and competitiveness in the European Union. However, transport emissions and pollutants in European highways threaten human health and the natural environment, negatively affecting local environmental quality and making a significant and growing contribution to climate change. The Egnatia Motorway is one of the first large-scale public works to apply a system of environmental management in the design, construction, operation, and maintenance stages of the project.
Through the “Environmental Highway Observatory E-HIGHWAY” project, within the framework of “Greece – The former Yugoslav Republic of Macedonia IPA cross border programme 2007-2013,” Egnatia Odos S.A. aimed to support better operational management of the highway and the protection of natural environment by establishing environmental monitoring and early warning systems (air/water/noise pollution).
The challenge faced by the project was how to establish effective air, water and noise monitoring along the Egnatia motorway and its vertical axes, without incurring a level of cost that would compromise the viability of the project.
In addition, Egnatia Odos S.A. is primarily responsible for construction, maintenance and operation of the motorway, without calibration and maintenance facilities or expertise necessary to support reference monitoring equipment. The mobility and small size of the system was also a factor – this would allow a greater range of sites to be selected as well as the ability to easily move the units from one place to another without the need for expensive site works and construction approvals.
Following an open tendering procedure, Egnatia Odos S.A. purchased two AQM60 compact air quality monitoring stations and worked with Aeroqual’s local partner, ScientAct S.A. www.scientact.com.gr to design and deliver an effective solution.
One of the AQM60 stations is housed within a vehicle along with calibrator, gas cylinders and a telemetry system which delivers data back to the control centre. The mobile unit conducts studies in multiple locations along the highway. The other AQM60 is deployed semi-permanently and is used to study air quality in each location over a period of 15 days. In locations where the mobile system identifies high variations or patterns which require deeper investigation, the second AQM60 is deployed for periods up to several months.
Both stations are configured to measure gaseous and aerosol air pollutants including nitrogen dioxide (NO2), oxides of nitrogen (NOx), carbon monoxide (CO), and particulate matter fractions of PM1, PM2.5, PM10 and total suspended particulates (TSP).
The data is gathered and processed by Egnatia Odos S.A. in collaboration with the Aristotle University of Thessaloniki, which also participates as a partner in the E-HIGHWAY project.
After several months of operation Egnatia Odos S.A. is building up a rich and detailed understanding of air quality along the transport corridor.
The AQM60 offers a real-time air quality monitoring platform that is truly mobile, stable and accurate. The customer finds the equipment easy to use and calibrate. Overall they are extremely satisfied with the ratio of performance and cost.
