3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations Defekt belgrospi se ne detektuje ovom metodom. Takođe, defekt dugačke naboranosti unutarnje šine u krivinama malog radijusa se teže detektuje ovom metodom. Za efikasno upravljenje šinskim defektima na ŽS, autori ovog rada preporučuju kombinovanje više nedestruktivnih metoda: vizuelnu inspekciju, ispitivanje ultrazvukom i vrtložnim strujama. U tom smislu, neophodna je hitna dopuna podzakonskih akata i edukacija stručnog kadra u oblasti održavanja železničke infrastrukture. ZAHVALNICA Ovaj rad je rezultat istraživanja na Tehnološkom projektu br. 36012 "Istraživanje tehničko-tehnološke, kadrovske i organizacione osposobljenosti Železnice Srbije sa aspekta sadašnjih i budućih zahteva Evropske unije", koje je finansirano od strane Ministarstva za prosvetu i nauku Republike Srbije.

3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations NOISE REDUCTION IN RAILWAY INFRASTRUCTURE Zdenka Popović, University of Belgrade, Faculty of Civil Engineering, Belgrade, Serbia Leposava Milosavljević, University of Belgrade, Faculty of Civil Engineering, Belgrade, Serbia Luka Lazarević, University of Belgrade, Faculty of Civil Engineering, Belgrade, Serbia Abstract: The tendency of applying urban rail systems for passenger transport grows in the urban environment, due to their advantage regarding direct and indirect ecological effects in comparison to other modes of transport. In this sense, the increase of railway transport will affect on reduction of air pollution, but at the same time it will increase noise level. This paper analyzes and suggests necessary measures for managing railway noise in planning, design, construction and maintenance of the railway infrastructure. It emphasizes the influence of separation of passenger and freight transport subsystems in the railway junction, rail routing with respect to terrain, track alignment design parameters and superstructure and substructure design. It is pointed out that efficient solution of the noise problem requires joint strategy of managing noise from vehicles and infrastructure. Efficient noise control is based on clearly defined legal regulations and technical standards. Key words: Serbian Railways, noise, infrastructure, environment, legislation ULOGA INFRASTRUKTURE U REDUKCIJI BUKE OD ŽELEZNIČKOG SAOBRAĆAJA Apstract: U urbanom okruženju raste tendencija primene šinskih sistema za prevoz putnika, zbog njihove prednosti u pogledu direktnih i indirektnih efekata u odnosu na druge vidove prevoza. U skladu sa time, očekivano povećanje obima železničkog saobraćaja uticaće na smanjenje zagađenja vazduha, ali u isto vreme i na povećanje nivoa buke. Ovaj rad analizira i predlaže potrebne mere za upravljanje bukom od železničkog saobraćaja na nivou planiranja, projektovanja, građenja i održavanja železničke infrastrukture. On ukazuje na značaj razdvajanja pitničkog i terenog saobraćajnog podzistema u železničkom čvoru, vođenja trasa železničke pruge u odnosu na teren, izbora elemenata situacionog plana, kao i konstrukcije gornjeg i donjeg stroja na smanjenje emisije buke. U radu se ističe da efikasno rešenje problema buke zahteva zajedničku strategiju upravljanja bukom od vozila i infrastrukture. Efikasna kontrola buke se zasniva na jasno definisanim zakonskim propisima i tehničkim standardima. Ključne reči: Železnice Srbije, buka, infrastruktura, životna sredina, regulativa 1. INTRODUCTION The countries that were signatories of the Protocol adopted in Kyoto on December 12th, 1997 committed to reduce the emission of harmful gases. Achieving the target of the reduction of emission of harmful gases requires the reduction of the influence of transport on the environment and reestablishing the balance between different modes of transport. Thus the relative competitiveness of railway transport compared to other modes of transport becomes quite significant (European Commission, 2011). European traffic policy expects a tripling of freight transport on rail by 2020, which will affect on reduction of air pollution and increase of road traffic safety (European Commission, 2011). By the assessments, consequences of this policy will be increase of noise from railway traffic by 5 dB(A). Control of railway noise has very significant part in the traffic policy of the EU. Considering an organization policy of railway traffic in Europe, main cause of night-time noise is traffic of freight trains. Daily noise level of railway traffic is determined by high speed trains traffic, conventional speed trains traffic and urban rail transit. This increase of noise will significantly reduce the quality of life of citizens. Enhanced noise firstly causes uneasiness, then irritability, tendency towards depression, insomnia, digestive problems, even Belgrade, 2012 252
