EGNATIA ODOS MOTORWAY - LONG TERM NOISE MONI- TORING & STRATEGIC NOISE MAPS Chonianaki Fotini Edt consultant engineers & GENV General Partnership, 28 th October, 28, 15451 Psychiko, Athens, Greece email: info@edtce.gr, edt@tee.gr Valkouma Thalia and Fourkas Vassilis Egnatia Odos S.A., 6th km Thessaloniki Thermi, 570 01 Thermi, Thessaloniki, Greece Sarantopoulos George University of Ioannina, Department of Physics, Laboratory of Meteorology, GR-45110 Ioannina, Greece Merkurios Koundouras HEAR Inc. The Egnatia Odos motorway (1000 km long with its vertical axes) crosses northern Greece (East Macedonia and Thrace Epirus). Aiming at sustainable development, EGNATIA ODOS SA introduces an innovative environmental management strategy during operation and maintenance of the motorway, protecting natural and human environment. Among others, the company aims at the effective management of road traffic noise. The company runs annually noise monitoring programs since 2006 and keeps a fully updated GIS database. Furthermore strategic noise mapping is implemented for the estimation of population exposure to noise and the need for action plans and mitigation measures, according to national and E.E. legislation. From 2013 to 2015 an extended monitoring program was performed based also on the approved environmental terms for the project operation, including 155 (24h) noise measurements per year, strategic noise mapping, estimation of population exposure to noise, comparison with the results of previous years. Noise measurements were distributed into seven geographical areas with further distinction in rural and suburban areas next to medium and large agglomerations. Traffic data were collected as well. For noise mapping, a complex geographical model was created using DTM & DSM model data, VLSO digital orthophoto-maps, survey data, etc. Technical features of motorway were inserted in detail. The model was calibrated using simultaneous real time traffic and noise data. The main conclusions were the following: a limited number of measurements exceeded the limits, seasonal variation was observed, noise levels were higher in suburban areas than in rural ones, the movements of heavy vehicles increased during night. Annually, the traffic volumes and noise levels tended to increase. Regarding noise mapping, there was no population exposure to noise levels above the limits. The area of the assessed noise zones was extended annually in a small rate. 1. Introduction The Egnatia Odos motorway crosses northern Greece serving connection with 11 agglomerations and 332 towns, 4 major Greek ports, 3 international and 3 local airports, 10 industrial areas, > 30 touristic sites, archaeological sites, protected nature areas, etc. Within the range of areas served - influenced from 1
Egnatia Odos are covered: 36% of population of Greece, 54% of agricultural activities, 51% of mining sites, 41% of industrial activities (in terms of employment), etc. It is linking Greece with the European countries and the Middle East through vertical collector axis of the European Transport Corridors running through the South-East Europe from North to South (European Corridors: IV Berlin - Sofia - Thessaloniki, IX Helsinki ending Alexandroupolis and X Vienna - Belgrade - Thessaloniki). Road alignment Area of influence & connections with European road network Figure 1: Egnatia Odos Motorway (project s alignment, area of influence and connection with European road network).[1] Aiming at sustainable development, EGNATIA ODOS SA has established a special depart, the Observatory, which is responsible to introduce and operate an innovative environmental management strategy during operation and maintenance of the motorway, protecting natural and human environment. Among others, the company aims at the effective management of road traffic noise 2. Principles and actions of implemented management of traffic noise In the context of management of road traffic noise the company : (a) runs annually noise monitoring programs since 2006 and (b) has performed strategic noise mapping and action plans for the years 2008(University of Thessaly & TT&E Consultants SA), 2013, 2014 and 2015,(Fotini Chonianaki, Edt Consultants Engineers). 2.1 Annual noise monitoring programs aims and structure The aims of Annual noise monitoring programs were: (a) to fulfil the approved environmental terms ( noise measurements along the highway at ekistics land uses in a range of 200m from the road side ), (b) to investigate potential serious annoyances from road traffic noise, (c) to monitor the evolution of road traffic noise level and (d) to calibrate the model used for noise mapping. The most important parameters are hereinafter described: In the context of annual noise monitoring programs (since 2006) were performed about 363 noise measurements of indices Leq and L10 (as per MD 17252/20.5.92 and the approved environmental terms provision) [1]. The period 2008-2009, the noise monitoring program was reformed to fulfil the provisions of directive 2002/49/EE. In 3 different seasonal periods were performed about 90 noise measurements (24hours) of the indices: Lden, Lday, Levening and Lnight (as per 2002/49/EC directive) LΑeq(08.00-20.00) (as per MD 17252/20.5.92), LΑeq(24h) and L10(18h. Measurements were especially selected for the elaboration of the relevant Strategic road traffic Noise Maps (SNM).[1] From 2013 to 2015 an extended monitoring program was performed, including 155(24h) noise measurements per year, based on the approved environmental terms and the needs of relevant Strategic Noise Maps (SNM). They were measured the indicators: Lden, Lday, Levening and Lnight (as per 2002/49/EC directive) and further more the LΑeq(24h), L10(18h), Lmax, Lmin, L1, L50, L90, L95 and L99. Traffic and meteorological data were recorded simultaneously to noise measurements. Measurements were performed in autumn (year 2013) and in spring (2014, 2015). They were used 6-7 autonomous noise monitoring stations (up to 7 noise level meters 2 ICSV23, Athens (Greece), 10-14 July 2016
2250 & 2270 Brüel & Kjær and cel550 & cel 490 CASELA) and meteorological station (DAVIS).The data of measurements were be kept in a fully updated GIS database.

S.N. Maps covers areas where Average Annual Daily Traffic-AADT exceed 10.000 vehicles (3.650.000 vehicles per year) and there are residential land uses next to Egnatia Odos Motorway (see Fig. 4 below). A total of 12 S.N. Maps were produced for 12 settlements and one around the city of Thessaloniki, all at region of Central Makedonia.

Main sources of data were the Observatory of Egnatia Odos, the National Cadastre & Mapping Agency SA (NCMA S.A) and survey. The main terrain data used were: D.E.M (digital eleva- ICSV23, Athens (Greece), 10-14 July 2016 3
tion model), D.S.M (digital surface model - Altitude Accuracy 1,18 meters for a confidence level of 95%), V.L.S.O very large scale orthophoto maps, recent stereo pair of aerial photographs all from NCMA S.A. The main data for the road alignment and bridges, tunnels, etc., were given from Egnatia Odos (recent topographic survey). Buildings shapefiles were created using the above data (outline polylines, height) and from survey (number of floors, uses per floor). Population per building were estimated using data from ELSTAT Hellenic Statistical Authority (number of households and population per block) and survey data. The geographical model described above was insert and further processed using the noise mapping software (Predictor Lima version 10). The model was checked, corrected and adjusted to noise mapping needs. Bridges, tunnel, interchanges, etc., were adjusted with special care. Figure 4: Indicative cases of adjustment of bridges, tunnel & interchange. 2.2.2 Traffic data Traffic data derived from relevant data from tolls and from measurements (simultaneously to noise measurements). The estimation of Average Annual Daily Traffic-AADT was bases to the above data. 2.2.3 Geographical model calibration Model results were find quite compatible with noise measurements results with a correlation coefficient which vary between noise mapping areas : Area 1 (Kouloura Klidi) : 0,81, Area 2 (Thessaloniki): 0,89, Area 3 (Evagelismos N Kerdilia): 0,95. 4 ICSV23, Athens (Greece), 10-14 July 2016

In the year 2013 noise levels were higher than those of 2014 due to the different seasons of the measurements. There were no excesses of the allowed noise limits, except for few cases in which there were noticed at EIII & EIV areas of non-residential use. The only spots where further investigation for measures is necessary are at the sanctuary of Agios Panteleimonas area (EIV) and at residential building of Liti. 3. Population exposure (ENV01) Population exposure estimation is presented at Table 3. There are no residents in zones of Lden>70 & Lnight>60dB(A) so for the present no action is necessary except for monitoring & noise mapping. Table 3: Population exposure.
