Average skidding distance for forest stands is an important parameter for the determination of the optimum road density and spacing. In this research the real mean skidding distance and theoretical me...
One of the cost factors in forest management is the development of road infrastructure. The objective of study was to develop a method using GIS and Multi-criteria Evaluation (MCE) to design a forest ...
The basic condition of forest management development is the accessibility of the forest. A design of the forest road network in relation to all-society functions of forests has been made in the catchm...
resources needed to plan these improvements, it is important to target these efforts based upon the available information. Previous research based on existing forest compartment and road network dat...
Forest road network in the Tokyo University Forest in Hokkaido plays an important role in selling low price trees, and has a key role in intensive forest management. Forest road network also contrib...
This paper describes a program for optimizing forest road alignments using the Dijkstra shortest path method and a cubic spline function.We previously developed a method for optimizing forest road ali...
The objective of the study was to estimate the carrying capacity of forest roads with slag and gravel pavements. Deformation module and elastic deflection were used as characteristic parameters of r...
Forest traffic infrastructure is one of the basic preconditions for good quality forest ecosystem management. Since 1991, when the Republic of Croatia gained independence and the company Hrvatske &#...
Optimization of forest road network is an important part of logging planning. Matthews (1942) was the first to introduce a method for optimization of road spacing based on minimization of roading an...
Road construction and harvesting operation have always been the two most expensive activities in forestry. The aim of this paper is to define a method to evaluate the forest road network variants. F...
This paper deals with the required width of forest road formation. Forest roads are necessary for emergency forest management. Besides positive effects, forest roads also bring negative effects. One...
During the forest road planning process, the determination of road routes requires the evaluation of many factors. The data needed for forest road planning are obtained from different sources with di...
