On certain Egnatia Motorway sections modern weather stations operate and collect weather data (wind, air temperature, frost, etc). Operating weather stations fall under two categories:
stations measuring Ambient Temperature
Road Weather Information Systems stations (RWIS)
Road Weather Information Systems, RWIS
AMBIENT TEMPERATURE MEASUREMENT STATIONS
At the East Region of the Egnatia Motorway, from Palio IC through Kipi, ambient temperature measurement sensors were installed. Data are collected automatically through wireless communication technologies (GSM, VHF), and they are accessible by maintenance crews through Web, WAP and SMS services. The information provided helps in optimising winter maintenance works (salt spreading, timely notification of snow ploughs, etc.).
The locations of ambient temperature sensors are the following:
Vaniano (West Xanthi)
Vafeika (East Xanthi)
Alexandroupoli Industrial Zone (BI.PE.)
Link Road BI.PE. - Alexandroupoli Port
ROAD WEATHER INFORMATION STATIONS
Weather data collection/ recording systems and systems that forecast local road weather phenomena, such as frost, wind etc contribute greatly to the prompt provision of information to users, as well as to the effectiveness of winter maintenance works.
On the Egnatia Motorway, Road Weather Information Systems, RWIS) operate on various road sections. Weather data transfer and processing is performed using telematics at the respective tunnel Traffic Control Centres.
