NFORMATION MODEL OF VEHICLE TELEMATICS DATA CLUSTER COLLECTION USING UAV

Telematics is a set of basic systems that provide services in accordance with user needs. Telematics systems can be classified according to the areas of tasks performed: monitoring the condition of the road, managing the flow of traffic, providing information services to road users, etc. Telematics also allows you to monitor the condition of vehicles or their cargo using remote monitoring methods and technologies. The use of telematic systems and technologies allows for real-time management of transport systems. The article is devoted to the development of an information model for collecting motor transport telematics data using unmanned aerial vehicles. A model of the V2R network type is considered in which one car in the cluster is defined as a central node that receives telematic information from other cars in the cluster and then transmits the collected information to the base station. It is proposed to replace the central vehicle with a specialized UAV that collects telematic information from all vehicles in the cluster and transmits the collected information to the base station. A formula has been obtained to calculate the maximum amount of information that can be collected and transmitted to the base station.

These tools enable authorities, operators and travellers to make more informed and 'intelligent' decisions. In addition, these tools improve transport management and increase efficiency and safety for public bodies while reducing energy consumption and environmental impacts, thus contributing to more sustainable transport.

Evaluation of interoperability to Ukrainian tank cars, as they are recognized for the transportation of non-healthy cargoes by railway transport

Ensuring safety during the transportation of goods by railway transport with the minimization of the level of risks is a priority task today. An analysis was made that shows that in Ukraine there are significant developments in the field of improving the design of wagons, their dynamic characteristics and safety. Manufacturers of railway cars strive to increase the number of new, high-quality and technically advanced (under the terms of interoperability) railway rolling stock in use. 11 interoperability specifications were considered: infrastructure; energy; management; noise; persons with limited mobility; safety in tunnels; freight cars; locomotives, passenger cars and rolling stock; freight transportation telematics; passenger transportation telematics; the movement of trains that are approved and currently in operation. The considered requirements and components of the Technical Certification of Interoperability and domestic normative documents for railway cars, namely: the requirements of the Technical Certification of Interoperability for freight railway cars; requirements of regulatory documents in Ukraine regarding tank cars; technical characteristics of tank cars produced in Ukraine. A comparative analysis was made of the conformity of the general technical parameters of tank cars manufactured in Ukraine, the principle of operation and design of brake systems of freight cars, the conformity of the dimensions of tank cars, regarding the determination of the dimensions of railway rolling stock (or the dimensions of rolling stock), the fulfillment of conditions under which it is possible the east of the rolling stock. Calculations were made for an empty car in the presence of a raised outer rail, as well as calculations of traffic safety criteria according to these standards. Taking into account the requirements for the production of modern rolling stock is a necessity, which is considered on the example of tank cars, which are currently produced for compliance with interoperability requirements, and the proposed priority measures to achieve the specified compliance

The Issue of Operating Security Systems in Terms of the Impact of Electromagnetic Interference Generated Unintentionally

This article discusses issues regarding electromagnetic interference generated unintentionally by transport telematics systems and electronic security systems (ESS) located within a railway area. These systems should operate correctly, since they ensure the safety of both vehicles and passengers. The electronic devices they use are exposed to electromagnetic interference that may lead to incorrect ESS functioning. In order to determine the impact of electromagnetic interference on ESS, the authors measured unintentional low-frequency electromagnetic field generated by MV—15 and 30 kV—power lines. This enabled determining the areas with maximum values of electromagnetic interference. The next stage of the research was to develop an ESS operating process model that takes into account the impact of unintentionally generated electromagnetic interference on the operating process. Introducing the electromagnetic interference impact coefficient enables a rational selection of solutions aimed at protecting against electromagnetic interference through the application of technical and organizational measures.

Quality and Reliability-Exploitation Modeling of Power Supply Systems

This article describes the issues related to the analysis of the reliability-exploitation of power supply systems in transport telematics devices (PSSs in TTDs). This paper characterizes solutions, which are applied in supply systems, and describes a PSS in a TTD from a main source and a standby one. This enables determining the dependencies denoting the probabilities of the system staying in full ability state, safety threat state, and safety unreliability state. A quality analysis of the PSS in TTD was conducted, and the indicator value of the supply continuity quality was evaluated. This indicator allows the demonstration of continuity quality of power supply (CQoPS) dependency on many quality dimensions, not just reliability. An example demonstrates the calculation of CQoPS factor for both the main and the standby power supply, employing three observations, each influencing the quality. The presented considerations in the field of quality and reliability-exploitation modeling of a PSS can be applied as well in other public utility facilities (including those classified as critical infrastructure). The character of functions performed by critical infrastructure facilities demands an operating continuity of these systems at an appropriate level. The co-first authors of the article once again address the issue of determining CQoPS factor, this time on the basis of modeling using mathematical evidence. TTD is an example in this article, because the presented methods can be used in any kind of system, especially in the power source of critical systems.

Method-oriented systematic review on the simple scale for acceptance measurement in advanced transport telematics.

Acceptance intuitively is a precondition for the adaptation and use of technology. In this systematic review, we examine academic literature on the “simple scale for acceptance measurement” provided by Van der Laan, Heino, and de Waard (1997). This measure is increasingly applied in research on mobility systems without having been thoroughly analysed. This article aims to provide such a critical analysis. We identified 437 unique references in three aggregated databases and included 128 articles (N = 6,058 participants) that empirically applied the scale in this review. The typical study focused on a mobility system using a within-subjects design in a driving simulator in Europe. Based on quality indicators of transparent study aim, group allocation procedure, variable definitions, sample characteristics, (statistical) control of confounders, reproducibility, and reporting of incomplete data and test performance, many of the 128 articles exhibited room for improvements (44% below.50; range 0 to 1). Twenty-eight studies (22%) reported reliability coefficients providing evidence that the scale and its sub-scales produce reliable results (median Cronbach’s α >.83). Missing data from the majority of studies limits this conclusion. Only 2 out of 10 factor analyses replicated the proposed two-dimensional structure questioning the use of these sub-scales. Correlation results provide evidence for convergent validity of acceptance, usefulness, and satisfying with limited confidence, since only 14 studies with a median sample size of N = 40 reported correlation coefficients. With these results, the scale might be a valuable addition for technology attitude research. Firstly, we recommend thorough testing for a better understanding of acceptance, usefulness, and satisfying. Secondly, we suggest to report scale results more transparently and rigorously to enable meta-analyses in the future. The study protocol is available at the Open Science Framework (https://osf.io/j782c/).

LIGHT REGULATION SYSTEMS IMPROVEMENT ANALYSIS TO FORECAST THE TRANSPORT FLOWS IN ALMATY

The number of vehicles on the roads of Almaty, Kazakhstan is growing from year to year. This brings about an increasing intensity and density of traffic flows in the streets which leads to congestion, decreasing speed of the traffic flow, increasing environmental pollution caused by car emissions, and which can potentially lead to the road traffic accidents (RTA), including fatalities.
 While the number of injuries grows up mainly due to drivers’ non-compliance with the speed limit, the environmental pollution is caused by longer traffic jams. Therefore, to reduce the level of road traffic injuries and emissions into the environment it is necessary to ensure the uniform movement of traffic flows in cities. Currently, one of the effective ways to do it is the use of transport telematics systems, in particular, control systems for road signs, road boards and traffic lights.
 The paper presents an analysis of existing systems and methods of traffic light regulation. The analyses of the systems and methods are based on the use of homogeneous data, that is the data on standard parameters of traffic flows. The need in collecting and analyzing additional semi-structured data on the factors that have a significant impact on the traffic flows parameters in cities is shown as well.
 The work is dedicated to solving the problem of analysis and forecast of traffic flows in the city of Almaty, Kazakhstan. GPS data on the location of individual vehicles is used as the initial data for solving this problem. By projecting the obtained information onto the graph of the city's transport network, as well as using additional filtering, it is possible to obtain an estimate of individual parameters of traffic flows. These parameters are used for short-term forecast of the changes in the city's transport network.

Impact of smart logistics on smart city sustainable performance: an empirical investigation

PurposeTechnologies continue to disrupt logistics and freight transport (known as smart logistics), but their impacts on smart city sustainability is underinvestigated. Drawing on technology, organisation and environment (TOE) perspective, the objective of this study is to empirically investigate the hierarchical effects of smart logistics on smart city sustainable dimensions (i.e. environmental, social and economic).Design/methodology/approachThe study used cross-sectional survey to collect data from urban transporters, warehouse managers, retailers and information technology (IT) managers in Australia. Data were analysed using structural equation modeling (SEM) to test the hypothesised relationship between constructs of smart logistics and smart city sustainable performance.FindingsThe findings reveal that information and communications technologies (ICTs) use and IT capability (ITC) have positive and significant effects on smart logistics. Technology-enabled smart logistics have an immediate positive effect on smart city environment, which in turn has positive impacts on social and economic performance.Practical implicationsThe study informs managers that smart logistics equipped with freight transport telematics can improve smart city environment through enhanced tracking and tracing of goods movement. The improved environmental stewardship is likely to support social and economic performance.Originality/valueSmart city research remains primarily theoretical and focussed on concerns surrounding sustainable growth amid urbanisation and digitalisation. City logistics and urban freights play key role in smart city economic growth, but vehicular pollution pose social and environmental challenges. Technology-assisted smart logistics are likely to improve smart city sustainable performance but yet to find how they affect each other.

Using transport telematics and remote diagnostics to improve vehicle maintenance and repair

The article considers the possibility of using planned-prevention system in modern conditions. The system of vehicle telematics and remote diagnostics allows you to automate the getting of correction coefficients to determine the standard values of labor intensity of maintenance and repair and make calculations with high accuracy. The mileage before major repairs or write-off of the vehicle set by the manufacturer is also corrected for coefficients. The use tools of navigation allows you to determine the location of the vehicle in the coordinates of navigation maps with characteristics of the road surface, locality, with the definition of height above sea level and road-climate zoning. This method is an alternative solution that allows you to automate the mileage and labor intensity of technical actions and can be used to clarification parameters. To implement these principles, we propose a flowchart for processing transport telematics data for calculating correction coefficients, followed by calculating the periodicity and labor intensity. The proposed flowchart is implemented by a standard vehicle telematics system, but it can be upgraded with the possibility of remote diagnostics, which allows performing the functions of general diagnostics of individual systems and the vehicle as a whole. The use of systems of transport monitoring make it possible to improve the system of maintenance and repair. Analysis of the existing requirements regulated by documents in the perspective of the capabilities of modern transport telematics systems allows us to justify and create a new approach to the calculation of mileage before technical impacts and adjust the standards for the complexity of performing these impacts. The introduction of the general remote diagnostics function for individual systems and the vehicle as a whole makes it possible to eliminate errors in the calculation of correction coefficients, as well as to prevent the occurrence of failures during operation.

Telematics – electronic data interchange / EDI / in port transport logistics

ABSTRACT The logistics and distribution function of ports includes various services, mainly circulation and optimisation, leading to minimising logistics costs and rationalising the distribution of goods during their flow from sender to recipient. The implementation of this function in many ports has become an opportunity for their activation and development, in recent years the demand for distribution services has clearly increased, seaports as part of transport chains are the most favourable place to locate such services. The functioning of these centres is now ensured by modern information and telecommunications technologies, whose combined application to move people and loads in geographical space has created a new field of science and practice, generally known as transport telematics. Previous scientific, implementation and experience research in the introduction and application of telematics technologies, i.e. the joint application of information and telecommunications technologies, has enabled the construction of numerous telematics systems, including in transport. It can therefore be concluded that telematics systems are technology innovations, and their functioning is ensured by the electronic exchange of EDI data, whose place and role in transport is indicated by the content of this article.

Remote Evaluation of Road Transportation Process

The article is devoted to development of a decision-making algorithm for transportation of goods by road based on the method of online remote assessment of the state of the cargo and the transportation process without human intervention. The development of the algorithm is based on the use of transport telematics and experimental study, the objective of which was to reveal capacity of navigation devices to fix accelerations that occur during vehicle movement. The developed methodology allows to automatically make decisions aimed at saving resources. The article describes the steps of operational remote assessment of the state of the cargo, as well as the decision-making algorithm based on the information received. A scheme of information interaction of the cargo transportation process participants is described, in which an analytical center is designated, the task of which is to calculate the force acting on the cargo and compare the calculated force with the strength characteristics of the material from which the cargo is made. The situational task of delivering goods to several points is described. To visualize the situational task, a cargo delivery route was constructed to compare planned indicators with actual ones, adjusted using the analytical center. This article describes the prospects for the use of tools of transport telematics, consisting in increasing the effectiveness of cargo safety control during transportation.

Вдосконалення технічного обслуговування і ремонту транспортних засобів

The article discusses the use of a planned preventive maintenance system in modern conditions using systems of monitoring of transport , which allows a more reasonable approach to the period of maintenance and create a new approach to calculating runs before technical impacts. Confirmation of the proposed method must be obtained by analyzing the data on failures using the available information and reference system. The analysis of statistical data is necessary to determine the criterion of necessity and sufficiency when performing maintenance. In order to reduce costs when performing maintenance and repair of vehicles, the intervals are set to the maximum possible regulated by the manufacturer, but exceeding the maintenance period is fraught with premature failure of individual systems and mechanisms, the restoration of which can be an order of magnitude greater than the savings in this approach. At the same time, the analysis of statistical data can identify the most vulnerable mechanisms and focus on them when performing technical maintenance. The work carried out to collect and analyze information about the structure of the bus fleet, the distribution of rolling stock by mileage since the beginning of operation, age and average annual mileage suggests that there is a significant influence of mileage and age of buses on the number of requests for repairs, as well as seasonal factors of operation. The analyzed failures and malfunctions of systems and units of bus operating in urban conditions require a balanced approach to determining the timing of maintenance and repair. For a correct description of operating conditions, roads, and road conditions, you can use indicators such as vehicle speed and load. When determining the load, is used parameter of the instantaneous or average fuel consumption, which can be determined using fuel flow and level sensors, as well as using data from the duration of fuel injection by injectors, as well as data from intermediate calculations in the vehicle's CAN data bus. These parameters can be read using the system of transport telematic, which will simplify calculations and obtain greater accuracy. The method of using vehicle parameters has the advantage of taking into account instantaneous data of the autobus operation and, in comparison with the traditional approach, will increase the accuracy of determining the timing of maintenance and remout, since the coefficient K1 depends on the speed and load over time when measuring instantaneous and average fuel consumption over the injection duration.

The Aspect of Power Supply in Exploitation of Transport Telematics Systems

Abstract Transport telematics systems operate under various operational conditions. As elements, which are responsible, among others, for the transport process safety, they should maintain their usability. One of the key problems is to ensure the power supply continuity in the transport telematics systems. In order to provide it, relevant power supply systems are used. The state of unfitness of power supply constitutes a failure in the system operation, the result of which can be downtime in operation of the entire transport telematics system or its part. The article carried out a reliability and operation analysis of the power supply system, which consists of three independent energy sources. The relationships, which allow to specify the probabilities of the system’s staying in the distinguished states, were determined.
