On Polish roads the problem of mortality of forest animals is more and more often noticeable. As a result of continuous development and modernization of roads in our country accompanying investments should be held, which aim is to minimize the amount of road incidents with participation of forest animals. The main cause of animals' mortality on roads is i.a. intersecting their migration cor-ridors by the road infrastructure.The aim of this article is to analyze the structure of road incidents with par-ticipation of forest animals.According to data collected concerning 2010 the Police reported 16 963 road incidents with participation of forest animals, including 157 accidents, 16 806 collisions, 6 persons killed and 208 injured. These are the losses seen from the environmental and the economic point of view. As results from the analysis carried out, national and voivodship roads, on which the great part of national and local vehicular traffic takes place, pose the greatest danger to forest animals. The least road incidents with participation of forest animals occur on motorways, which are in most cases fenced. The largest amount of road incidents with participation of forest animals occurred on Fridays, Saturdays and Sundays. It results from the increased vehicu-lar traffic ...
The increasing importance of the transport forces modernization of many road stretches. The changes in the transport are not meaningless for the natural environment - the fauna. In order to determine the exact number of animals dying on roads the study was undertaken, which aims at creating a mobile method of in-ventorying animals which died as a result of road incidents. The proper method will be used among others to conduct the study of the effectiveness of the applied security systems, which aim at decreasing the number of collisions with animals and will enable the outlining the migration corridors. In the study presented there was analyzed the usage of the mobile method with a digital camera installed on a specialist car.The preliminary study showed the influence of many factors on the study ef-fectiveness. These factors were among others weather conditions, the speed of the study vehicle, the time, which passed since the road incident took place etc.It results from the study conducted that the average effectiveness of the mo-bile method amounted to 31.65%. As far as the analysis is concerned, which took into account only the reptiles and the amphibians - the average effectiveness of the study amounted to 27.69%. ...
The development of the road infrastructure, migration ways of animals crossing with roads increase the possibility of a road incident with animals. The road incidents with animals are the source of multimillion financial losses and can cause permanent disabilities and even death of the road users. In order to increase safety and decrease the negative impact of road on the natural environment, the research should be conducted and the appropriate safety features decreasing the probability of animals rushing on to roads should be used.The aim of the study was to analyze the road incidents with animals on Polish roads between 2001 - 2011. In the study the road incidents with big animals i.e. with the deer (deer, fallow deer, elk, roe deer) and wild boars were analyzed. In the researched period the tendency of changes for: the number of road incidents with animals, the number of animals, the number of registered vehicles was analyzed. It was calculated, how often it came to a road incident with animals.In the researched period 2001 - 2011 it came to 153,269 road incidents with animals, including 151,882 collisions, 1,387 accidents in which 61 persons died, 1,804 were injured. The increase of road incidents with ...
Development of road infrastructure and growing number of vehicles on the roads increase the probability of road collisions with wild animals (fallow deer, stag, moose, roe deer or wild boar). In order to improve the safety and decrease the number of wildlife vehicle collisions, it is justifiable to determine the time intervals in which the probability of road accidents involving animals occurs, including seasonal, monthly and daily changes over the whole year. The research comprised an analysis of the structure of road collisions involving wild animals in the years 2001-2011, including the division into seasons, monthly and daily intervals. The data of the number of road traffic collisions involving animals were obtained through an analysis of the data base of Police Headquarters in Warsaw. The identified structure of seasonal and daily road collisions involving animals revealed that the highest number of accidents happened in autumn (29.36%) and spring (26.60%). Almost 10.88% of the analysed accidents happened in October and c.a. 10.62% in May. In the daily structure, the highest probability of collision was after the sunset. These changes are related to daily and seasonal migration due to animal behaviour and the traffic density. ...
