Abstract One of timber harvesting purposes is moving wood from the forest to sawmills. Road network planning requires consideration for alternatives. This paper purposed determine decision-making in selection alternative road networks with utility analysis by considering economic, ecological, and social criteria. The indicator used were length road, open area, cost construction, felling, skiddi...

Skidding operations induce changes in soil physical properties, which have the potential to impact soil sustainability and forest productivity. Our objective was to investigate the effects of traffic frequency, trail slope, and soil moisture content on soil compaction, total porosity and rut depth. Treatments included a combination of three different traffic intensities (3, 7, and 14 passes), t...

Salvage logging is increasing in Central Europe because of the growth severe meteorological events, and timber harvesting these conditions challenging terms both productivity performances safety operations. In recent years, with increase natural calamities, several researchers studied machinery regarding salvage carried out by ground-based systems. fact, a common post-disturbance management app...

Forest operations can lead to increased runoff and soil loss on roads skid trails. The aim of this study was evaluate the effectiveness two erosion control treatments applied different segments trails following six natural rainfall events. A total 162 plots 10 m long by 4 wide were established in a Hyrcanian deciduous forest assess ground-based harvesting traffic. experimental setup consisted t...

Considering that forests are crucial in the ecosystem of our planet and provide timber products as well several services, it is evident application sustainable forest operations (SFOs) substantial importance to achieve management (SFM). One most important issues be evaluated when dealing with SFOs limiting disturbance impacts related logging. Harvesting activities can indeed alter conditions so...

Mobile robots are increasingly being used in challenging outdoor environments for applications that include construction, mining, agriculture, military and planetary exploration. In order to accomplish the planned task, it is critical that the motion control system ensure accuracy and robustness. The achievement of high performance on rough terrain is tightly connected with the minimization of ...

This paper gives a global dynamic analysis of a two wheeled riding simulator that we have built and instrumented for the study of drivers behavior. These studies concern drive situations in normal urban scenario as well as dangerous driving situations such as skidding. The justification of the choice of the platform movements for a good feeling is discussed. Different models for inverse kinemat...

This paper presents innovations for detection of obstacles and road using a Multilayer Laserscanner. The classification of pedestrians and other road users require robust object tracking algorithms. Their reliability strongly depends on a precise ego-motion compensation. A new method of ego-motion estimation based on relative velocities of tracked objects will be introduced. This method operate...
