This paper focuses on elements of transport policies affecting energy efficiency of road haulage. The purpose is to present a tool developed to support decision making during the policy making process, at the stage of formulating the elements of transport policies. The paper describes a model developed to assess the impact of policy instruments on fleet energy efficiency by multi-criteria ranking applying the Analytical Network Process. The paper describes the possibilities to employ the defined model giving the example of international road haulage in the Republic of Serbia. The application led to a proposal for policy instruments which could have the highest impact on the increase of energy efficiency in this sector and which will be considered further in detail during the policy formulation process.

This paper presents the research on vehicle fleet energy efficiency impact upon overall vehicle effectiveness. Transport companies and companies with own vehicle fleets tend to enhance their resource effectiveness, and to increase their transport service quality with the objective of attaining a competitive position on the market. Since energy consumed for transport operations is an important transport process resource, a method for assessing transport process effectiveness has been developed with the objective of increasing vehicle fleet effectiveness and its energy efficiency, and the overall vehicle effectiveness human indicator has been defined accordingly. The developed method was then implemented in an actual vehicle fleet and variations of the overall vehicle effectiveness human indicator were researched, as well as specific energy consumptions for respective net transport volumes depending on the following indicators: vehicle payload capacity utilization rate and mileage utilization rate. It is shown that specific energy consumption influences overall vehicle effectiveness depending on both the payload capacity utilization rate and mileage utilization rate.
