“…The very dangerous factors of the working environment and the working process of private forest entrepreneurs are unfavorable microclimates, increased working load, noise and bad lighting [9,10,11]. Inappropriately high work length during the day, insufficient work breaks, inappropriate conditions for a balanced diet coupled with harmful manufacturing factors create fatigue and a considerable vulnerability to worker health damage.…”

Abstract. From the aspect of safety at work, we consider the timber transport under the risky works. Data about accidents at work in forestry for the period 1996 -2014 were summarized. The database contained more than 1500 work accidents in forestry. Laboratory Accident Coding Methodology was used, according to European Statistics on Accidents at Work (ESAW). In total, 105 registered work accidents in timber transport, during the investigated period, were recorded. This correspond to 7% share of registered work accidents. From the anthropological aspect, the legs and whole body were most frequently injured. The highest number of accidents on Tuesday were recorded, with the most risk month of February. The highest accident rate in 2002 were recorded. In general, forestry is classified as a risky activity. The timber harvesting and transport process belongs to the most risky works, from the aspect of the risk formation on the work accident, which are in forestry conducted. From all phases, which are in this process involved, the phase of timber transport is the least risky, in terms of the risk rate on accident formation as well as the absolute abundance of accidents.

“…Measurements in Zvolen (ZV) took place on 3 October 2011 and 24 April 2015. The results of measurements from this measuring point (ZV) were published in the works of Němec et al [ 10 , 30 , 31 ]. The data from these measurements are used in the statistical analysis, therefore the results are repeatedly partially published in this paper.…”

“…The measurement methodology, as well as the calculation of predictions, were performed in the same way as in the published research in the papers Němec et al [ 10 , 31 ]. The literature [ 34 , 35 ] characterize the exact methodological procedure, which was followed in the measurements performed in this research.…”

Rail transport is the second most important way of transporting people and freights by land in the European Union. Rail noise affects around 12 million people in the European Union during the day and around 9 million at night. There are two possible ways to assess environmental noise: noise measurement in situ and prediction using mathematical models. The aim of the work is based on the performed measurements and selected noise predictions to evaluate the accuracy of the prediction models and assess their sensitivity to various aspects. Two measuring points in the Banská Bystrica Self-Governing Region, within Slovakia, were selected for measurement, which is characterized by increased mobility of the population. For prediction, the two methodologies were selected (Schall 03 and Methodical instructions for the calculation of sound pressure level from transport). The results show that the Schall 03 method is sensitive to the measurement location (the value reaches half of the significance level) and to the location–period interaction. The second prediction method is sensitive to systematic error (absolute term) and, such as Schall 03, to the location–period interaction. This method systematically overestimates the results. Results showed greater accuracy of both prediction models compared to the measured noise values than the results of the authors in other countries and conditions.

“…The basic factors determining noise from road traffic include the influence of operation and vehicle construction and factors connected to the environment and its surroundings. The derived factors cover the factors connected to the method of traffic operations [10][11][12][13][14][15][16].…”
