MODELING OF THE OPTIMAL DISTRIBUTION OF MOTORWAY OVERPASSES ON THE EXAMPLE OF THE A4 MOTORWAY SECTION

Abstract

The developed, innovative method of estimating the impact of motorway on agricultural land allows determination of all the losses associated with the directions of this impact. The basis for the determination of losses is the analysis of variability in land use and the quality classes and location of access roads to the land along the axis of the planned motorway. The approved measure of the multidirectional impact of the motorway on agricultural land is a change in the value of land, which is designated taking into account the differentiation of their suitability for agricultural production.
The developed method of determining the impact of motorway on agricultural land was presented on the example of A4 motorway section between Bratkowice and Mrowla. The existing section of motorway was assessed and then for the same section the calculations were made again, but with an alternative location of the motorway overpasses.
In the case of the existing section, the construction of one kilometer of the section of motorway under consideration will result in a reduction in the value of agricultural land of 1725 cereal units. Acquisition of land for the construction of the motorway and its negative impact cover about 69% of the total reduction in value of agricultural land. The remaining 31% of the land value reduction is related to the increase in transport and the deterioration of the parcels layout. On the other hand, in the case of the section with alternative arrangement of viaducts, the value of agricultural land is reduced of 1538 cereal units. Acquisition of land under construction and its toxic impact will be equal 75%, while the combined effect of transport growth and deterioration of the layout makes 25%.
