General Model of Accident Rate Growth in the Construction Industry

The accident level in sectors of the national economy is estimated from such data as: the number of persons employed in the analysed sector, the number of victims of accidents at work and the frequency and seriousness of the accidents. The data have a static character: they inform about the accident level in the analysed period but not about its variation over time. Also the pace of work contributes to accidents at work. The accident level and the production volume change over years. It is essential to be able to determine the rate of variation of two quantities. For this purpose a model enabling the assessment of dynamic changes in the investigated phenomena has been developed. Besides accident indices the model takes into account indices which measure the economic effects of construction production.
