“…During log transportation, forces affect both the load and the vehicle. These are usually seen as separate elements, and their priority and the complexity of their interactions are disregarded [40]. Twelve experts participated in the expert evaluation, assessing the impact of the forces (Table 3).…”

When transporting different types of cargo, the factors affecting the cargo must be assessed to ensure a safe and fast transportation process. However, the specificity of the cargo means that the standard assessment methods do not reflect the existing conditions or are standard at the theoretical and/or recommendation level. Therefore, in the event of a traffic accident, when a vehicle or cargo is damaged or other traffic participants are put at rink, assessment of the situation is difficult and requires an expert assessment. Then, the most optimal means of accomplishing this is to simulate transportation parameters with a specific vehicle and cargo. The transportation of wooden logs is a very specific method of transportation where, in addition to the weight of the load itself, it is necessary to assess how the load affects the dynamics of the vehicle. Therefore, determining the priority of the forces that act on the vehicle carrying wooden logs becomes very important in order to model the transport parameters of this cargo. This article uses an analytical survey, an expert survey and its analysis, and methods to determine correlations. Given the fact that the main forces acting on the load most often manifest during a turn, this study assessed road turns and the respective speed on them as the main parameters. Other parameters, such as road roughness and roundabouts, were not assessed, because they would be an object of long-distance research. The study results revealed that the main forces affecting a vehicle transporting logs manifest in the following priority order: inertial forces, gravity forces, frictional forces and, finally, centrifugal forces.

“…Initially, the rank correlation method presented by Kendall [43] was used. From the ranks of the studied criteria, applying new average rank transformation into weights linear and non-linear (average rank transformation into weight-linear-ARTIW-L and average rank transformation into weight-non-linear-ARTIW-N) methods [44], the normalized criteria weights were calculated. The experts also provided percentage importance estimates for the criteria, which were used to calculate all the normalized weights of their subjects using the direct percentage weight (DPW) method.…”

Asphalt pavement, a component of transport infrastructure, deteriorates under the influence of destructive factors. The damages which have occurred during its period of use are repaired and the asphalt pavement is recycled when its further rehabilitation is economically and technically irrational. The material from the asphalt pavement layer that has reached its limit state is milled out or broken and crushed and then is repeatedly used in the production of hot-mix asphalt (HMA) or warm-mix asphalt (WMA) mixtures. In this paper, the dynamics of the percentage recycling ratio (RR) of old asphalt pavement material was investigated. RR represents the quantity of reclaimed asphalt pavement (RAP) used in the production of HMA and WMA mixtures in Europe and the USA, divided by the total amount of RAP prepared in the country. Factors and goals affecting it are analyzed. An original system of 10 criteria that increase the RR country has been created. Decision makers do not know which factors have the maximum influence in increasing the use of RAP and this should go in connection with environmental pollution reduction and achieving economic utility. By applying different multiple-criteria decision-making (MCDM) methods and using the importance given to these criteria by 14 experts, the normalized subjective weights of the criteria were determined. Analytic hierarchy process (AHP), rank correlation, average rank transformation into weight—linear (ARTIW-L) and non-linear (ARTIW-N), and direct percentage weight (DPW) methods were used in the study. The results show that the RAP recycle rate is close to 100% in countries with a sustainable economic background. In the Baltic countries, it is mostly increased by the adequacy of regulatory documents, the strategy promoting asphalt recycling in the country, and the homogeneity and classifying of RAP. The number and capacity of RAP stocks, the number and productivity of asphalt milling equipment and the wear and tear of the asphalt pavement have the least influence on the increase in RR. The opinions of experts in assessing the significance of all criteria are consistent. The averages of the weights of criteria determined by four MCDM methods (AHP, ARTIW-L, ARTIW-N, DPW) made it possible to obtain more reliable results. These results can be used to make strategic decisions and to create a plan of practical actions to increase the RAP recycling rate in the developing countries.

Freight transport by road is constantly increasing, therefore it is very important to ensure efficient distribution of flows by optimizing/reducing transport costs. With the recent increase in the demand for small loads, less-than-truckload transportation services are becoming increasingly popular among representatives of small and large businesses. This method of cargo transportation is more economically accessible and useful. The increasing competition between companies encourages the search for ways to improve the offered services, thereby reducing costs for customers. Digitization tools are among the most important in order to implement the principles of green logistics, ensure long-term competitive advantages by systematically improving logistics results and reducing costs. Automated service management, services based on customer data and intelligent solutions must help companies create a digital business model. The purpose of this article is the identification of problem areas in the service quality of companies carrying out less-than-truckload transportation on international routes and ways of solving them by applying digitization technologies. Research methods/methodology used: the work was carried out based on the analysis of scientific literature, statistical data analysis and survey methods, an expert survey was conducted by means of a questionnaire. The analysis of scientific literature made it possible to identify that the transportation of less-than-truckload shipments is not considered as a separate element, but included in the process of transportation of general loads. Considering the fact that less-than-truckload cargo transportation is becoming increasingly popular globally, this renders it possible to justify the novelty of the article and for a more detailed study. The result of the work is a conceptual model of service quality improvement based on digitization technologies.
