Influence of technical parameters of overpasses on wildlife migrations and economic aspects

This article deals with how technical parameters of overpasses affect animal migration. Sustaining of migration animals - ecological aspect of construction - is being more and more discussed. There is also an effort to minimize the cost at the same time. It is obvious that the bigger the overpass is the higher probability of migration will be however the cost will also increase. There is an effort to provide sufficient migration and keep the cost low. Article examines how technical parameters of overpasses affect medium size mammals migration. Large amount of data was obtained from spy game video, pictures, scout camera records, etc. Logit model has been found to be a suitable tool for this purpose. Obtained results were further used for economic analysis.
