Soil trafficability analysis

The mobility is one from the most important factor during military operations. Soils cover most of the Earth´s surface, therefore the military planners rely heavily on soil analysis. With regard to cross-country movement (CCM), we differentiate individual types and sorts of soils. Soils affect the speed of movement of a vehicle by various ways, depending on factual weather conditions given, first of all by the total amount of precipitation of area given and also by the temperature regime. Soils and climatic conditions are closely linked with regard to cross-country movement. The aim of this paper is the identification of main soil factors that affect the cross-country movement modelling and the ways how we determined that factors. There are included some classifications of soil types, vegetation cover and surface roughness factors affecting the cross-country movement in paper. There is also expressed the common impact of Rating Cone Index (RCI) and Vehicle Cone Index (VCI) on vehicle route deceleration.
