Abstract
Forest road planning is a time-consuming and complicated process both because it requires environmentfriendly road building, and due to the requirement to observe economic costs. This costs will be increase depending on maneuverability requirements of vehicle dimension. The main aim of this study is to analyze maneuverability of recreational vehicles on forest roads that primarily serve utilization of vehicles intended for production as well as geometrical characteristics of roads on computer environment. Both dynamic horizontal driving analysis and dynamic vertical driving analysis can be made with Autopath driving analysis module of Plateia 2013 software. Computer-aided horizontal driving analysis, which is used in examination of opportunities for utilization of available roads by different vehicle types, appears as an effective method for the decision maker in consideration of geometrical standards of vehicles during decision-making process. Graphical report is another output of driving analysis which visually presents vehicle maneuverability. In this context, Maneuverability of automobile, midibus and bus were analyzed on forest road with 4 m platform width. As a results of this study, it was concluded that computer-aided driving analysis is a beneficial tool in decision making process for re-planning of forest roads. As a consequence, it is considered that driver safety, as well as project costs, would increase by utilization of driving analysis during forest road planning and design.
Highlights
The earliest developments in road technique started with the invention of wheel around 5000 B.C
Certain significant studies attempted to exhibit the utilization opportunities for above mentioned software in planning forest roads and forest road networks (Akay 2003; Altunel 2006). Both dynamic horizontal driving analysis and dynamic vertical driving analysis can be made with Autopath driving analysis module of Plateia 2013 software, which has been analyzed within the scope of this study (Fig. 1)
It was observed that results obtained from driving analysis method, which was exercised for the first time on forest roads, could be used effectively at the stage of planning forest roads or during utilization of different vehicle types on available forest roads
Summary
The earliest developments in road technique started with the invention of wheel around 5000 B.C. Roads that comprise the infrastructure of shipment and transportation play a vital role in performance of forestation activities; transportation of forest products, produced within the forest, from the place of production to industry or consumption centers with the most convenient methods by the most affordable means, as well as ensuring sustainability of the forest during the process, require planning of road networks (Bayoglu 1997). Forest roads can be defined as: “Structures that ensure transportation of wood-based and non-wood forest products from where it is produced to where it will be used”. These roads operationalize forests in addition to ensuring transportation of wood raw materials, personnel and equipment, as well as satisfying road requirements and recreational demands of forest villages. In order for production procedures to be effective, safe, comfortable and
