The purpose of the article is to study the information aspects of the activities of a motor transport enterprise, to build a communication network within the enterprise, which seeks to fully satisfy the needs of society for the transportation of goods and passengers. Methodology. The study was carried out using graph theory - one of the major branches of discrete mathematics, which is widely used in solving economic and management problems. Using these methods, the minimum path in the information network is found. Results. The quality and timeliness of information coming in the forward and backward directions determines the quality of management of individual objects of the road transport system, as well as the possibility of its coordinated functioning in order to fully satisfy the needs of society for the transportation of goods and passengers. The article examines the introduction of information technologies in transport, which are used at all stages of receiving, storing, processing and transmitting information, should fully ensure the timeliness and high quality of information support when making managerial decisions at all levels of the transport system. The general principles of the construction and functioning of motor transport systems are analyzed through the prism of the information procedures implemented in them and the emerging information flows. It has been established that most of the total volume of information processed in a company can be information necessary for the management and control of logistics operations. Since the road transport system is geographically distributed, a modern specialist must master the methods of spatial analysis based on geoinformation technologies. The development of the information and communication infrastructure of a new transport company, which plans to carry out the transportation of goods by road, has been investigated. The company will provide services such as cargo transportation, freight forwarding services, cargo tracking, cargo insurance, settlement of cargo deliveries, cargo unloading and loading. For the optimal placement of the company's network, graph theory is used. An optimal communication network has been built, connecting various departments of the company, namely, the transportation department, the office, the accounting department, the economic planning department, the legal department, the mechanical department, the communications department, and the personnel department. The scientific novelty of the article is the use of the method for constructing an optimal communication network at a trucking company. The practical significance of the work is that this method can be used at any transport company that begins its activity to build communication links between any departments of the company. In this case, these connections will be optimal.

On The Road

The dimensions and weight of machines, structures, and components that need to be transported safely by road are growing constantly. One of the safest and most widely used transport systems on the road today due to their versatility and configuration are modular trailers. These trailers have hydraulic pendulum axles that are that are attached in pairs to the rigid platform above. In turn, these modular trailers are subject to limitations on the load that each axle carries, the tipping angle, and the oil pressure of the suspension system in order to guarantee safe transport by road. Optimizing the configuration of these modular trailers accurately and safely is a complex task. Factors to be considered include the load’s characteristics, the trailer’s mechanical properties, and road route conditions including the road’s slope and camber, precipitation and direction, and force of the wind. This paper presents a theoretical model that can be used for the optimal configuration of hydraulic cylinder suspension of special transport by road using modular trailers. It considers the previously mentioned factors and guarantees the safe stability of road transport. The proposed model was validated experimentally by placing a nacelle wind turbine at different points within a modular trailer. The weight of the wind turbine was 42,500 kg and its dimensions were 5133 × 2650 × 2975 mm. Once the proposed model was validated, an optimization algorithm was employed to find the optimal center of gravity for load, number of trailers, number of axles, oil pressures, and hydraulic configuration. The optimization algorithm was based on the iterative and automatic testing of the proposed model for different positions on the trailer and different hydraulic configurations. The optimization algorithm was tested with a cylindrical tank that weighed 108,500 kg and had dimensions of 19,500 × 3200 × 2500 mm. The results showed that the proposed model and optimization algorithm could safely optimize the configuration of the hydraulic suspension of modular trailers in special road transport, increase the accuracy and reliability of the calculation of the load configuration, save time, simplify the calculation process, and be easily implemented.

The goal of civil engineering has always been the research and implementation of methods, technologies, and infrastructures to improve the community’s quality of life. One of the branches of civil engineering that has the strongest effect on progress is transport. The quality of transport has a profound economic and social impact on our communities regarding trade (freight transport) and city livability (public transport systems). However, innovation is not the only way to improve the features above-mentioned, especially public transport, considering that it is usually beneficial to enhance and repurpose vehicles with appropriate adjustments to offer more efficient services. Other perspectives that influence public transport systems are the costs and times of design and construction, maintenance, operating costs, and environmental impact, especially concerning CO2 emissions. Considering these issues, among the various types of existing public transport systems, those of the so-called Bus Rapid Transit (BRT) offer worthwhile results. The BRT system is a type of public road transport operated by bus on reserved lanes, and it is significantly profitable, especially from an economic point of view, in areas where there are existing bus routes. Nonetheless, for the construction of works minimization, it is closely linked to other features that improve its usefulness, depending on the vehicles’ quality such as capacity, but above all, the propulsion or driving autonomy that would guarantee high efficiency. This paper introduces an analysis of some BRT systems operating worldwide, presenting the background, general technical features, and the correlation with autonomous vehicles.

The Impact

The social cost, as one of the factors determining sustainability of socio-economic development, is strongly dependent upon a number of casualties and mortality in road accidents. The condition of car tires appears to be one of the important factors determining the occurrence of accidents. The vast majority of vehicles are tested every year at vehicle inspection stations. One of the elements affecting the result of the technical condition test and basically the quality of vehicle braking is the technical condition of the tires. Their technical condition is a very important factor responsible for the quality of acceleration, braking, maintaining, or changing the direction of driving. As a consequence, it has a significant impact on road safety. The aim of the study is to examine the impact of tires on the results of tests performed at a vehicle inspection station. The study presents the results of bench measurements of the impact of selected features of tire condition of two vehicles during routine periodic inspections at a vehicle inspection station (VIS). The focus was on an attempt to assess the impact of inflation pressure, age, and tire tread wear on the braking process. The technical studies performed might be a source for legal steps assuring better management of road safety. It can also be expected that the tire choice and condition may affect fuel consumption, and therefore the amount of energy consumed by the road transport.
