Open, broken, and improperly closed manholes can pose problems for autonomous vehicles and thus need to be included in obstacle avoidance and lane-changing algorithms. In this work, we propose and compare multiple approaches for manhole localization and classification like classical computer vision, convolutional neural networks like YOLOv3 and YOLOv3-Tiny, and vision transformers like YOLOS and ViT. These are analyzed for speed, computational complexity, and accuracy in order to determine the model that can be used with autonomous vehicles. In addition, we propose a size detection pipeline using classical computer vision to determine the size of the hole in an improperly closed manhole with respect to the manhole itself. The evaluation of the data showed that convolutional neural networks are currently better for this task, but vision transformers seem promising.

Driver assistance systems have started becoming a key differentiator in automotive space and all major automotive manufacturers have such systems with various capabilities and stages of implementation. The main building blocks of such systems are similar in nature and one of the major building blocks is road lane detection. Even though lane detection technology has been around for decades, it is still an ongoing area of research and there are still several improvements and optimizations that are possible. This paper offers an Optimized Dynamic Origin Technique (Optimized DOT) for lane detection. The proposed optimization algorithm of optimized DOT gives better results in performance and accuracy compared to other methods of lane detection. Analysis of proposed optimized DOT with various edge detection techniques, various threshold levels, various sample dataset and various lane detection methods were done and the results are discussed in this paper. The proposed optimized DOT lane detection average processing time increases by 9.21 % when compared to previous Dynamic Origin Technique (DOT) and 59.09 % compared to traditional hough transform.

Autonomous vehicles (AVs) are receiving attention in many countries, including Thailand. However, implementing an intelligent transport system has many challenges, such as safety and reliability and the lack of policy supporting such technology use, leading to hazards for passengers and pedestrians. Hence, factors affecting the adoption of autonomous vehicles require better understanding. This research proposes and employs an extended Technology Acceptance Model (TAM) by integrating ethical standards, legal concerns, and trust to predict the intended use of autonomous vehicles by Thai citizens. A total of 318 questionnaires were collected from online panel respondents. Research hypotheses were tested using a structural equation modelling approach. The study results suggest that ethical standards have a significant positive effect on the intention to use the technology. Meanwhile, the intention was negatively affected by perceived usefulness, perceived ease of use and legal concerns. On the other hand, the results indicate that perceived ease of use directly affected trust, leading to AV adoption. However, other factors influenced trust insignificantly. This study demonstrates the vital role of trust in AV adoption. The study also suggests ideas for further study and discusses the implications for the government and autonomous vehicle companies. The article aims to forecast a success factor that the Thai government should use to consider the policy for autonomous vehicle adoption in Thailand. This paper relies on the technology acceptance model to assess and forecast autonomous vehicle adoption. The theoretical model also includes ethical issues, legal concerns and trust in technology. The model was analysed using the structure equation modelling technique to confirm the factor affecting Thailand’s successful autonomous vehicle adoption. This research confirmed that ethical standards, legal concerns, and trust in technology are the factors significantly affecting the intention to use an autonomous vehicle in Thailand. On the other hand, the perceived ease of use significantly affects the trust in autonomous vehicle technology. This research found that such social factors as ethical standards, legal concerns, and trust in technology affect technology adoption significantly, especially technology related to AI operation. Therefore, the technology acceptance model could be modified to confirm technology adoption in terms of social factors. The government could use the research results to develop a public policy for the regulation and standard supporting autonomous vehicle adoption in Thailand.

In order to improve the safety and comfort of autonomous vehicles passing through the expressway, relevant departments of expressway construction often design and lay consecutive speed control humps (SCHs) with cross-sections of different shapes according to different road conditions, such as the combination of trapezoidal and sinusoidal SCHs. In this paper, we conduct a study about the nonlinear dynamic characteristics of the autonomous vehicle passing through hybrid SCHs. Firstly, a four-degree-of-freedom (4-DOF) nonlinear model of the vehicle suspension and the speed coupling excitation model under hybrid SCHs are established. Then the fourth-fifth order Runge–Kutta method is used to simulate the nonlinear system, and its nonlinear dynamic characteristics are analyzed. The results show that chaotic motion occurs when the vehicle passes through hybrid SCHs, and the speed range of chaotic motion is obtained. Then, a direct variable feedback control method is used to suppress the chaotic vibration of semi-active suspension vehicles, and the effect is verified by simulation experiments. Finally, this paper presents a multi-objective optimization model based on a genetic algorithm (GA) for active suspension vehicles. The optimization model selects the vertical displacement and pitching angle of the vehicle body as the objective function. The research results of this paper can provide information on the ride comfort’s optimization for autonomous vehicles passing through hybrid SCHs and on the design of vehicle suspension system.

Pojazdy autonomiczne to jeden z wiodących trendów technologicznych początku XXI wieku. Zmiana w sposobie myślenia o przemieszczaniu się w przestrzeni miejskiej otwiera nowe możliwości użytkowe. Jedną z grup, dla których wykorzystanie pojazdów autonomicznych może mieć szczególne znaczenie, są osoby niewidome oraz niedowidzące. Dysfunkcja narządu wzroku, która dotychczas całkowicie wykluczała ich z grupy użytkowników samochodów, może okazać się nieistotna w przypadku korzystania z pojazdu autonomicznego. Kluczem do udanego procesu użytkowego pomiędzy niewidomym użytkownikiem a autonomicznym pojazdem staje się sposób kontroli oraz wymiany informacji pomiędzy nimi. Technologia pojazdów autonomicznych będzie znacząco zmieniać branżę motoryzacyjną. Wdrażanie coraz większego poziomu automatyzacji funkcji doprowadzi do całkowitej autonomiczności pojazdów, w których pasażerowie nie będą musieli obsługiwać manualnie pojazdu. Szczególną grupą użytkowników, których może dotyczyć ta transformacja technologiczna, są osoby niewidome lub osoby z dysfunkcją narządu wzroku.

Autonomous vehicles are one of the leading technological trends of the early 21st century. A change in the way we think about moving around in urban spaces is opening up new usability opportunities. One of the groups for which the use of autonomous vehicles may be of particular importance are blind and partially sighted people. Visual impairment, which has so far completely excluded them from the group of car users, may turn out to be irrelevant when using an autonomous vehicle. The key to a successful user experience between a blind user and an autonomous vehicle is how they control and exchange information. Autonomous vehicle technology will significantly change the automotive industry. The implementation of increasing levels of automation of functions will lead to fully autonomous vehicles where passengers will not have to manually operate the vehicle. A particular group of users likely to be affected by this technological transformation are blind or visually impaired people.

Background: Along with the development of Industry 4.0, the concept of Logistics 4.0 is also developing in parallel. Some researchers emphasize that the fourth industrial revolution in the area of logistics concerns in particular warehouse services. New technologies related to automatic data identification and autonomous vehicles are increasingly appearing in warehouse processes. In particular, the implementation of autonomous vehicles in processes carried out so far by people generates significant challenges related to the proper preparation of the entire system, but also its coordination with processes carried out in the enterprise. The aim of the article is to present the results of the analysis of disturbances occurring in the first stage of the implementation of autonomous vehicles in the process of feeding material production lines in a surveyed company from the automotive industry. Methods: The article presents the implementation assumptions for the use of autonomous robots in the process of materials feeding. The scope of the required safety analyzes was presented as well as the time measurements carried out regarding the implementation of the process of servicing power supplies for assembly lines. The research used direct observations in the assessed enterprise and unstructured interviews with persons responsible for the implementation. Results: The results show the deviations from the adopted assumptions, both in the area of vehicle safety and the deviations in the time of material supply operations. It is worth noting that both positive and negative deviations from the adopted standard were recorded in the measurements. Based on the analyzes of the causes and effects of the deviations, guidelines have been developed for the changes to the functioning of autonomous vehicles. Conclusions: The results of the presented research allowed to identify potential adverse events that may occur in the process of implementing autonomous solutions in logistics service processes. The basic rules for the implementation of autonomous solutions in logistic operations, which are carried out in anthropotechnical systems, were also indicated.

The article presents selected issues from the conducted research and analyzes in the field of the development of autonomous vehicles, carried out under the project: Polish road to Automation of Road Transport. The development of autonomous cars is a global challenge for the automotive industry. The creation of a fully autonomous vehicle capable of transporting passengers and goods without the participation of a driver has become a priority goal of automotive concerns. The huge costs incurred by automotive concerns for the development of autonomous vehicles prove the progressing automotive revolution, which will have a significant impact on the shape of future transport systems, transport based on autonomous transport. Very often in the literature there are overly optimistic forecasts for the development of autonomous vehicles, as well as overestimating the benefits they are to bring, without pointing to the costs and problems of their implementation and functioning in the real transport system. The publication presents forecasts for the development of autonomous vehicles as well as the related risks and advantages of their implementation. The factors that have a significant impact on the development of these vehicles are also outlined.

Strengthening road safety in the face of the enormous development of the automotive in recent decades is crucial. The safety benefits of automated vehicles are paramount. Automated vehicles have the potential to remove human error in road traffic, which will help protect drivers and passengers, as well as pedestrians and bicyclists. The carried-out forecasts are pioneering for Polish road traffic conditions. In England, studies have been carried out to determine the estimated impact of autonomous vehicles on road safety in simulated traffic conditions on the motorway. In Poland, preliminary forecasts of the reduction in the number of road accidents were made; however, they were based on other assumptions. Therefore, estimating the impact of using autonomous vehicles in order to increase the level of road safety is an innovative activity for Polish road conditions. For the purposes of this article, available statistical data on vehicles registered in Poland, their equipment with advanced driver-assistance systems as well as accident data and their causes were analyzed. A diagnosis of Road Safety in Poland in 2018 (base year for further estimations) was made, taking into account the trend of recent years together with an indication of the most common causes of road accidents. These data were compiled with statistical data from other countries about the influence of driversupport systems on traffic safety. Possible potential for increasing Road Safety in Poland by the year 2030 was estimated. The analyses were prepared assuming different types of processes related to traffic, road safety, and the recent development of the passenger car fleet in Poland. Presented results show four scenarios of road safety change, where the number of accidents is reduced with statistical average of 5000 reduction in the year 2030. These expectations are based on various predictable factors connected with upgrade of car fleet quality and take into account changes in road safety observed in recent years. Based on the current trend of driving automation and rapid development of driver-support systems, the provided estimations were found reliable and likely. The conducted research shows the benefits and the need for the use of driver-assistance systems in vehicles as they can measurably affect the level of road safety.

Autonomous driving is no longer just an idea of technology vision instead a real technical trend all over the world. The continuing development to a further level of autonomy requires more on mobile robots safety while bringing more challenges to human-vehicle interaction. A robot autonomous vehicle (AV) as a research platform operates an experimental study on human-AV-interaction (HAVI) and performs a novel method for mobile robot safety assurance. Not only autonomous driving technology itself but human cognition also performs an essential role in how to ensure better autonomous mobile robot safety. A Wizard-of-Oz experiment in the university combing a survey-based study indicates public attitudes towards driverless robot vehicles. HAVI experiment have been carried through light patterns designed for experiment. This paper presents an attempt to investigate humans’ acceptance and emotions as well as a validation to bring the mobile robot vehicle to a high-level autonomy.

W artykule przedstawiono większość możliwych problemów i ryzyk współpracy z obecnym funkcjonowaniem transportu jak również możliwych do wystąpienia w przyszłości. Przeprowadzona analiza problemów prawno-ekonomicznych wskazuje na szereg trudności wdrożenia pojazdów autonomicznych, które mogą spowodować, poza ewidentnymi pozytywnymi rozwiązaniami, również duże ryzyko w zakresie bezpieczeństwa ruchu drogowego oraz konieczności dostosowania obecnych aktów prawnych. Należy dążyć do maksymalnego odzysku materiałowego z pojazdów wycofanych z eksploatacji (PWzE) w tym z elektroniki i instalacji elektrycznych nowoczesnych pojazdów EV/HEV szczególnie „bogatych” w metale deficytowe i krytyczne. Złom elektryczny i elektroniczny klasyfikowany jest najczęściej jako odpad niebezpieczny w grupie odpadów przemysłowych. Wiąże się to przede wszystkim z zawartością w nim związków szczególnie szkodliwych dla zdrowia ludzi i środowiska, a zarazem mocno pożądanych.

The majority of society, including politicians, scientists and visionaries, see only the advantages of implementing autonomous vehicles into road traffic, forgetting about the possible dangers and risks associated with the functioning of such transport. The article presents most of the present and future possible problems and risks of cooperation between autonomous vehicles and the functioning of transport. The conduced legal and economic analysis indicates a number of problems with the implementation of autonomous vehicles, which may cause, apart from obvious positive solutions, also a high risk in terms of road safety and the need to adapt the current legal acts. We should strive for maximum material recovery from end-of-life vehicles, including electronics and electrical installations of modern EV/HEV, particularly “rich” in scarce and critical metals. Electric and electronic scrap is most often classified as hazardous waste in the group of industrial waste. This is mainly due to the content of compounds that are particularly harmful to human health and the environment and at the same time highly desirable.

A primary goal of the Internet of Things is to create smart spaces, including smart cities and intelligent transportation system (ITS). One of the ITS variants is smart hybrid public transportation system, whose efficient development requires a broad support from the side of information and communication technologies (ICT). For such a system to function optimally, vehicles that are part of it have to be able to exchange data with other road users and road infrastructure. This applies especially to autonomous vehicles, whose trajectories may be in the future controlled through the vehicle-to-infrastructure (V2I) communication network. In the paper we propose a system that can be used to optimize the boundaries of relatively small suburban zones, in which public autonomous vehicles would be allowed to operate. Vehicles of this type may offer the transport only to the nearest local railway stations, from which the travel to the central city of the agglomeration would be continued for example by train. The concept of the proposed solution is based on the Voronoi diagrams, in which particular suburban train stations are treated as local attractors. The proposed software system in one of its stages uses Google Maps engine that allows for the determination of road distances and travel times between particular towns. On the basis of such data it determines the mentioned zones. Their boundaries, as well as optimal routes in a given period of the day may be communicated to the vehicles through the V2I system. The system performance is presented for an exemplary case of Poznan city, Poland.

Na świecie, a także i w Polsce toczy się ożywiona dyskusja dotycząca przyszłości transportu, w tym transportu miejskiego i autonomicznego. Postęp technologiczny (w tym: technologie informatyczne, technologie nowych systemów pomiarowych, nawigacji satelitarnej, zasobników energii elektrycznej itp.) stwarza nowe możliwości rozwiązań i prawdopodobnie w najbliższym czasie zrewolucjonizuje transport, w tym transport miejski. Ta nadchodząca rewolucja niesie ze sobą nie tylko wyzwania techniczne, ale również potężne wyzwania w obszarze legislacji, konieczność zmian w mentalności ludzi itd. W przekonaniu autorów zmiany w transporcie w najbliższym czasie wpłyną istotnie na wszystkie aspekty naszego życia, podobnie jak maszyna parowa czy technologie internetowe. Szczególne znaczenie odegra sztuczna inteligencja i związana z nią autonomizacja transportu. Problemem, który z perspektywy Polski jest też przedmiotem dyskusji, jest odpowiedź na pytanie: na ile Polska będzie tylko beneficjentem technologii, które wraz z postępem na świecie, niejako „przyjdą do naszego kraju”, na ile zaś Polska będzie współtworzyć nowe technologie? Artykuł poświęcony jest przede wszystkim autonomicznemu transportowi miejskiemu i stara się odnieść go do postawionych wyżej kwestii.

There is a lively discussion in the world and in Poland regarding the future of transport, including urban and autonomous transport. Technological progress (including: information technology, technologies of new measurement systems, satellite navigation, energy storage, etc.) creates new solutions and will probably revolutionize transport in the near future, including urban transport. This upcoming revolution brings not only technical challenges, but also huge challenges in the area of legislation, the need for changes in the people’s mentality, etc. Authors' believe that changes in transport in the near future will affect significantly all aspects of our lives, just like a steam engine or Internet. The artificial intelligence and the associated autonomy of transport will play a special role. The problem that from the Polish perspective is also the subject of discussion is the answer to the question: To what extent will Poland be the beneficiary of technology, which along with the world's progress, will "come to our country", how much Poland will co-create new technologies? The article is devoted primarily to autonomous urban transport and strives to relate it to the above issues.

The growing need of ocean surveying and exploration for scientific and industrial application has led to the requirement of routing strategies for ocean vehicles which are optimal in nature. Most of the op-timal path planning for marine vehicles had been conducted offline in a self-made environment. This paper takes into account a practical marine environment, i.e. Portsmouth Harbour, for finding an optimal path in terms of computational time between source and end points on a real time map for an USV. The current study makes use of a grid map generated from original and uses a Dijkstra algorithm to find the shortest path for a single USV. In order to benchmark the study, a path planning study using a well-known local path planning method artificial path planning (APF) has been conducted in a real time marine environment and effectiveness is measured in terms of path length and computational time.

In the future there will be a lot of changes and development concerning autonomous transport that will affect all participants of transport. There are still difficulties in organizing transport, but with the introduction of autonomous vehicles more challenges can be expected. Recognizing and tracking horizontal and vertical signs can cause a difficulties for drivers and, later, for autonomous systems. Environmental conditions, deformity and quality affect the perception of signals. The correct recognition results in safe travelling for everyone on the roads. Traffic signs are designed for people that is why the recognition process is harder for the machines. However, nowadays some developers try to create a traffic sign that autonomous vehicles can use. Computer identification needs further development, as it is necessary to consider cases where traffic signs are deformed or not properly placed. In the following investigation, the advantages and disadvantages of the different perception methods and their possibilities were gathered. A methodology for the classification of horizontal and vertical traffic signs anomalies that may help in designing better testing and validation environments for traffic sign recognition systems in the future was also proposed.
