Abstract

Modelling the sound pressure levels of traffic noise at any location in an urban area requires a series of steps in order to collect, collat and report data, in accordance with the European Community legislation (Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002). The  present paper presents a model performed through SUNET (System for Urban Noise and Eco-Traffic) system, including data collection equipment (Sound Metter Level UC2010-2, Weather Station (Tehno Line WS 550), software to process them (SoundPLAN) and harmonised indicators (Lden and Lnight - A-weighted long-term average sound level as defined in ISO 1996-2: 1987)  in order to validate the results. The  study  refers to a major road section in agglomeration Cluj-Napoca and considers all aspects regarding the urban area (type of road, architecture, buildings etc.) and traffic (speed, traffic composition, traffic density flow etc.). Measurements made in major roads in Cluj-Napoca reveal overcoming of limit values for almost all intervals of day. Even if for the road network from Cluj-Napoca, many actions were taken, like lower speed limits, heavy traffic prohibited, improved surface course, the maximum values allowed for 2012 are exceeded and more actions are needed in order to achieve these targets. Monitoring noise levels on the urban road network through the equipment and methods according to the law leads to actual results and an appropriate implementation of action plans.
