Developing Methods for Truck Route Selection and Cost Modeling in Steeper Topographies

Abstract

Abstract Payment tariffs for logging truck transport in Nordic countries are typically based on the loaded transport distance. Local tariffs often provide a good representation of the mean cost, however, as variation in topography and the transport environment increases; loaded distance alone represents the actual cost poorly. In addition, routes with increasing curvature also constitute more frequent braking and acceleration cycles. Moreover, driving in such topographical environments during the winter raises additional safety and operator stress issues. This study examines the situation in Norway where logging truck routes often start in mountainous regions. It tests the applicability of a route-generation system developed in Sweden and determines if it can be adopted in Norway. The case study is based on 30 detailed routes from each country, reported and analyzed by their respective transport managers. Based on typical local tariffs, the results show the route-specific variation in costs and profit margins associated with the varying transport environments. A framework for classifying transport environments is proposed as a basis for tariff agreements that better represent the actual transport cost. This increases fairness and supports economic sustainability for transporters.
