Supervised machine learning can be an effective method of predicting a target variable, depending on current values of independent attributes, if historical data containing values of independent attributes and target variables in the past is available and if some machine learning algorithm gives good results on the available data set. In this resea...

Due to the great market competition, transport companies face the need to reduce their vehicle fleet costs. The vehicle fleet managers’ actions on the driver’s driving style to achieve fuel consumption savings are measures to increase the fleet’s energy efficiency. The authors developed a model for evaluating driving style using a type-2 fuzzy logi...

In this paper, research is done in the influence of different terrain and traffic conditions on road sections on the driver?s driving performances, i.e. on the car energy efficiency and CO2 emission. A methodology aimed at determining to which extent unfavorable traffic and/or terrain conditions on a road section contribute to the driver?s worse dr...

The efficient vehicle procurement is an important business segment of different companies with their own vehicle fleet. It has a significant influence on reducing transport and maintenance costs and on increasing the fleet’s energy efficiency. It is indispensable that managers consider various criteria from several aspects when procuring a vehicle....

Main task of this paper is to present idea of selfmaintaining and make corresponding concept of selfmaintaining vehicles. Through setting parameters of selfmaintaining and providing algorithm of selfmaintenance in vehicles author made attempt to set basic principles in this area of research. Paper presents researched suitability of different drive-...

This paper analyzes the effects of intercity bus suspension system oscillatory parameters on driver's ride comfort and road damage. The analysis has been carried out through simulation by means of validated in-plane bus model with six degrees of freedom excited by real road roughness signal. Low root-mean-square values of the weighted vertical acce...

It is well known that fuzzy logic is a processing tool in circumstances lacking of clear linguistic information, as well as making conclusions based on imprecise assertions and rough data. Eco-driving rules that the drivers should comply with are not always made of concrete values (exact acceleration / deceleration rates, torque or headway / distan...

Integrated fleet maintenance management represents implementation of measures, actions and decision making with the aim of decreasing total maintenance costs and increasing energy efficiency fulfilling requirements of three interdependent components: transport, maintenance and their environment. Therefore, a methodology for integrated fleet mainten...

In this paper is researched how to achieve an effective fleet maintenance planning in transport companies, which contributes in increasing the fleet energy efficiency and in achieving the companies’ goal. Within the fleet maintenance planning, managers have to make the right decisions on the selection of vehicle service centers in the region where...

Companies with own vehicle fleet for freight transport try to carry out the requested transport volume, with lowest possible transportation and maintenance costs. In order to make energy efficient and rational, the vehicle fleet operation the influence of the maintenance management has been considered in this paper. In this sense, a concept of main...

The paper refers to the importance of maintenance management to increase the vehicle fleet energy efficiency. The fleet maintenance management influences as the vehicle maintenance process itself as well as the primary transport process but also their environment. In order to increase fleet energy efficiency by means of a more efficient maintenance...

Pravovremena i tačna informacija o vremenu isporuke robe koja se otprema iz nekog skladišta je od ključnog značaja i za isporučioca i za primaoca. Vreme isporuke robe koja se prevozi drumskim saobraćajnicama zavisi od brojnih objektivnih i subjektivnih faktora. U radu je predstavljen prototip aplikacije nad bazom podataka koja za zadati putni nalog...

Transport represents an industry sector with intense energy consumption, the road transport sector within is the dominant subsector. The objective of the research presented in this paper is in defining the activities which applied within road freight transport companies contribute to enhancing vehicles’ energy efficiency. Vehicle fleet operation ma...

Nowadays in the developed countries regarding transport related CO2 emissions a large attention is given to disfavouring the individual motorized traffic. Most measures are based on decreasing the usage of cars, eventually modal change to a more environmentally favourable modes as walking, cycling or public transport, congestion charging especially...

The main idea behind this paper is to impose restrictions on private cars’ admittance to restricted areas due to their \“weight efficiency”. We must take into account that energy efficiency is a direct consequence of the work realized and that the CO2 emissions are also proportional to this value. In essence, the intention is to minimize the vehicl...
