The negative effect of traffic noise on human health is indisputable. The article illustrates the magnitude of this problem in selected European capitals using data made available by the European Environment Agency, collected as a part of strategic noise mapping under Directive 2002/49/EC. The purpose of the described studies is to determine the number of people suffering from noise-induced health problems, and to compare the effect of the road noise on human health with the effect of noise from rail vehicles. Studies concern noise annoyance, induced sleep disturbance, and Disability-Adjusted Life Years, or DALY index. Analyses clearly show that environmental pollution from road noise often exceeds environmental pollution from railway noise by a factor of 10. In addition, studies show that in many cities, more than half of the population is exposed to road noise exceeding the acceptable values. The worst of all selected agglomerations with regard to people exposed to road and rail noise is Paris, the capital of France. It should be noted, however, that it has the highest population density of all the analyzed cities and a very well developed transport network. Further studies are needed to characterize the effect of traffic noise on inhabitant health more accurately, using specific indicators allowing to do so.

The main objectives of the introduced Directive 2002/49/EC are to harmonize the activities intended to control the harmful effects of noise pollution and to standardize the methodology for their assessment. Strategic acoustic maps drawn up in the EU Member States allow for determining the state of environmental noise pollution and planning preventive measures. This study involved analyses of noise levels in selected European capitals and Polish cities. The number of inhabitants who may be affected by a high degree of sleep disturbance caused by railway noise was also analyzed. An attempt was made to present a correlation between the scale of noise exposure and population density, the length of the existing railway infrastructure, and the type of areas with railways running through them. The most unfavorable type of development in terms of the number of people exposed to noise is compact development located directly along railway lines. Thanks to the acoustic maps, it is possible to locate the most noise-polluted places and establish a hierarchy of protective measures.

The Directive (2002) establishing the assessment and management of environmental noise mandates that the Member States of the EU to prepare action plans to manage noise-related issues and consequences of acoustic impact on areas adjacent to the busiest roads, railway lines, main airports and the biggest agglomerations. Every five years there are environmental noise control plans developed in the EU countries for the biggest cities with a population exceeding 100 thousand inhabitants. Each plan contains a set of proposed remedial measures aimed at improving noise conditions of the areas that have the greatest number of inhabitants exposed to noise above the limit values. As a rule, a few selected remedial measures are possible to apply in those areas and their combined effect is meant to result in a sensible improvement of noise conditions. In most programs, the tasks related to protection against environmental noise are based on single methods, which often present little effectiveness and are unrelated to other programs and policies.The present report describes the results of studies and analyses that were performed in most Polish cities where noise control plans were delivered. The studies enabled to determine the basic problems encountered in relation to noise control plans as well as issues confronted while adopting actual measures protecting the environment against noise. The conclusion points out the necessity to introduce changes in the approach to noise protection measures and methods in cities

Current literature on the performance characteristics of road surfaces is primarily focused on evenness, roughness and technical durability. However, other important surface properties require analysis, including noisiness, which is an important feature of the environmental impact of vehicular traffic around roads. This can be studied using various methods by which road noise phenomena are investigated. The method used to measure the noise performance of road surfaces herein is the Statistical Pass-By (SPB) method, as described in ISO 11819-1:1997. The impedance tube method was used for sound absorption testing, as described in ISO 13472-2:2010. These tests were performed under a variety of conditions: in situ and in laboratory. The existence of relationships between them can be helpful in selecting surfaces for noise reduction. Preliminary surface noise tests can be performed in the laboratory with samples consisting of various compounds. This is less expensive and faster than doing so on purpose-built surfaces. The paper presents study results for sound absorption coefficients of various types of low-noise surfaces in in situ conditions (on an experimental section and on operated road sections) and in the laboratory setting. The results of the tests performed on the operational sections were compared to the results of the surface impact on road noise using the SPB method. The correlations between the test results help confirm the feasibility of road surface pre-testing in the laboratory and the relation to tests performed using the SPB method under typical operating conditions.
