Restrukturyzacja rolnictwa i ocieplenie klimatu spowodowały intensywny napływ ludności, zwłaszcza z terenów wiejskich, do dużych miast w poszukiwaniu pracy. Odczuwają to także miasta średniej wielkości, jak Opole. Zwiększony ruch pieszych, duża liczba poruszających się pojazdów w obszarze danego miasta, wymusza potrzebę wdrożenia nowych rozwiązań w sterowaniu miejskim ruchem dro gowym. Wzorem dużych metropolii takich jak Shanghai, Tokio oraz Londyn stopniowo również pol skie miasta wprowadzają tzw. Inteligentne Systemy Transportowe, zwane jako grupa ITS. Opracowa nie niniejsze jest poświęcone temu tematowi. Wskazuje działania już podjęte, na przykładzie miasta Opole i daje propozycje dalszych realizacji. Poprzez przeprowadzenie wywiadu wśród uczestników ruchu pieszego, jak i kierowców pojazdów, zebrano oceny dotyczące funkcjonowania jeszcze frag mentarycznych rozwiązań w zakresie ITS. Wskazano do możliwie szybkiej realizacji prowadzenie kolejnych systemów teleinformatycznych, w tym inteligentnej sygnalizacji świetlnej, a także rozwiązań infrastrukturalnych na określonych newralgicznych skrzyżowaniach ruchu miejskiego.

Agricultural restructuring and global warming have caused a significant influx of people from rural areas, especially to large cities, so as to search of work. This phenomenon is also observed in medium-sized cities like Opole. Increased pedestrian traffic and the large number of vehicles in urban areas re-quire the implementation of new solutions in urban traffic management. Following the example of large metropolises such as Shanghai, Tokyo, and London, Polish cities are gradually implementing the so-called Intelligent Transport Systems, also known as ITS. This study includes this topic, that is it presents actions already undertaken in Opole and offers suggestions for further implementation. Interviews with pedestrians and vehicle drivers were the basis of assessments of the functioning of the still fragmented ITS solutions. Further ICT systems, including intelligent traffic lights, as well as infrastructure solutions at specific critical urban intersections, were recommended for rapid implementation.

Today, traffic accidents are still a difficult and urgent problem for many countries around the world. Traffic accidents on highways are often more serious than accidents on urban roads. Therefore, disseminating emergency information and creating immediate connections with road users is key to rescuing passengers and reducing congestion. Thus, this study applies data fusion and data mining techniques to analyze travel time and valuable information about traffic accidents based on the real-time data collected from On-Board Unit installed in vehicles. The results show that this important information is the vital database to analyze traffic conditions and safety factors, thereby developing a smart traffic information platform. This result enables traffic managers to provide real-time traffic information or forecasts of congestion and traffic accidents to road users. This helps limit congestion and serious accidents on the Highway.

The demand for Electric Vehicles (EVs) is increasing exponentially in recent times because of its ability to minimize energy savings and carbon emission. However, the charging process and charging option increases the challenges for EV adoption. With the growing adaptability to EVs, the need for addressing the challenges related to limited range and the availability of charging infrastructure becomes crucial. This paper presents an optimized deep learning-based charge scheduling approach in EVs for intelligent transport systems. The study leverages the Deep Reinforcement Learning (DRL) for making real-time decisions. The DRL model is trained using various features such as Battery critical percentage (SOC), time slots, nearest charge station, and availability of charging station. The features are optimized using a nature inspired Whale Optimization Algorithm (WOA), which helps in obtaining optimal charge scheduling. The proposed approach is experimentally evaluated in terms of reducing the tow counts in the selected region. Results from the experimental analysis validate the efficacy of the proposed approach in achieving optimal charge scheduling and navigation for EVs which also improve energy efficiency and reduce charging costs and charging time.

Recent years have witnessed increased attention towards vehicular communications as a part of an overall modernization trend towards the emergence of a reliable, less human-dependent, and more efficient Intelligent Transportation System (ITS) conjugated with the rapid growth of smart cities. ITS imposes better safety and security through the employment of Autonomous Vehicles (AV) to reduce the possibility of accidents caused due to human intervention. The application of autonomous vehicles to the traditional Vehicular Ad-hoc Networks (VANET) has paved the way for the development of a newer networking paradigm called the Internet of Autonomous Vehicles (IoAV). IoAV enjoys several advantages over VANET in terms of robustness, security, and scalability. However, due to the gradual transition from existing vehicles to autonomous ones, both types may be going to coexist together in the same environment. Therefore, a reliable, fast responsive, and flexible infrastructure is necessary to serve both kinds in such a hybrid setting until the transition to all AV is completed. In this context, this paper represents a concise review of the architecture of IoAV infrastructure, its communication modules, message dissemination, protocols and services that comprise the main body of the IoAV framework, in addition to further remarks and research challenges.

Urbanization has created continuous growth in transportation demand, leading to serious issues, including infrastructure overload, disrupted traffic flow, and associated vehicular emissions. As a result, resolving these problems has become one of the primary missions of governments worldwide. The optimization of the traffic signal timing system is considered a promising approach to overcoming the negative consequences of increasing vehicle volume. In metropolises, oversaturated intersections, where the traffic density and vehicle exhaust emission levels are significant, have been considered as the priority to target. Several scientists have attempted to design traffic lights with the most appropriate timing. However, the majority of previous studies have not formed a comprehensive evaluation of essential factors, especially regarding the appropriate weighting of vehicle emission parameters. By assessing the all-inclusive relationship of critical elements with an emphasis on vehicle exhaust emissions, a performance index model using a genetic algorithm (GA) is established in this paper, demonstrated by data from a case study in Taiwan.

We present vehicle detection classification using the Convolution Neural Network (CNN) of the deep learning approach. The automatic vehicle classification for traffic surveillance video systems is challenging for the Intelligent Transportation System (ITS) to build a smart city. In this article, three different vehicles: bike, car and truck classification are considered for around 3,000 bikes, 6,000 cars, and 2,000 images of trucks. CNN can automatically absorb and extract different vehicle dataset’s different features without a manual selection of features. The accuracy of CNN is measured in terms of the confidence values of the detected object. The highest confidence value is about 0.99 in the case of the bike category vehicle classification. The automatic vehicle classification supports building an electronic toll collection system and identifying emergency vehicles in the traffic.

Miasta w ostatnich latach ulegają dużym przemianom. Dzieje się tak nie tylko z powodu systematycznego powiększania się populacji zamieszkujących miasta (rozległe metropolie czy wręcz megapolis) i wynikających z tego faktu problemów, ale także w związku ze zmieniającymi się potrzebami ich użytkowników czy też zmianą polityki w urbanistyce. Rozwiązaniem wielu z tych problemów ma być nowa forma miasta jako nowoczesnej, inteligentnej struktury przestrzennej realizującej postulaty ekologiczne. W kierunek ten wpisują się z pewnością inteligentne rozwiązania w postaci nowoczesnych technologii, na których w niedalekiej przyszłości miałoby się opierać funkcjonowanie miast, np. w zakresie transportu czy kontroli jakości powietrza etc. Zaprezentowany cykl publikacji dotyczy rozwiązań technicznych, które mogłyby być wdrożone w nowoczesnych przestrzeniach zurbanizowanych. Bardzo ważna przy tym jest strona technologiczna na etapie implementacji owych rozwiązań, co również zostało poruszone w prezentowanym poniżej materiale.

Cities have undergone major changes in recent years. This is not only because of the systematic expansion of the population living in cities (large metropolises, or even megapolis) and the resulting problems, but also in connection with the changing needs of their users, or changes in urban policy. The solution to many of these problems could be the new form of the city, as a modern, intelligent spatial structure that implements ecological demands. Smart solutions, in the form of modern technologies, on which the functioning of cities would be based in the near future, e.g. in the field of transportation or air quality control, are certainly part of this direction. The presented series of publications concerns technical solutions, that could be implemented in modern urbanized areas. The technology side is very important at the stage of implementing these solutions, which was also discussed in the material presented below.

Współczesne miasta stawiają czoła różnym problemom, które częściowo wynikają również ze zmian struktury potrzeb mieszkańców. Odpowiedzią na niektóre z nich ma być idea tzw. miast inteligentnych dotycząca ich rozwoju w różnych obszarach związanych z funkcjonowaniem terenów zurbanizowanych. Jednym z ważniejszych systemów w miastach jest transport. Zapewnia on ich funkcjonowanie, dlatego nie jest możliwe całkowite jego wyeliminowanie, stąd też rozważania nad regeneracyjnym dla środowiska miejskiego wpływem wprowadzenia inteligentnych technologii do systemu transportowego. Przedstawiony zestaw publikacji zawiera techniczne rozwiązania, zarówno te dotyczące przestrzeni miejskich, jak i inteligentnych rozwiązań dla miast w przyszłości. To właśnie dostosowanie do użytkowników zależy od szczegółów związanych z implementacją partykularnych technologii lub innych rozwiązań. Zaprezentowany cykl opracowań przedstawia kwestie bezpośrednio związane z transportem inteligentnym, a także z potencjałem, jaki może przysłużyć się nowoczesnej, proekologicznej urbanistyce.

Contemporary cities face various problems, which partly also result from changes in the structure of residents’ needs. The answer to some of them is the idea of the so-called intelligent cities based on their development in various areas related to the functioning of urbanized areas. One of the most important systems in cities is transportation. It ensures their functioning, therefore it is not possible to eliminate it completely. Hence the considerations on the regenerative effect of the urban environment on the impact of introducing intelligent technologies into the transport system. The presented set of publications contains technical solutions, both regarding urban spaces and intelligent solutions for cities in the future. Because it is the adaptation to users, that depends on the details related to the implementation of particular technologies or other solutions. The presented series of studies presents issues directly related to intelligent transport, as well as the potential that can contribute to modern, proecological urban planning.

This article contains results of studies on the applicability of data from Intelligent Transportation Systems (ITS) for the purposes of geographical studies regarding the spatial mobility of inhabitants within a big city. The article focuses on the option of applying two types of sub-systems – induction loops and automatic number-plate recognition (ANPR) – and includes examples of analyses based on the resulting data, which can serve as a basis for mobility studies. The area on the example of which the capabilities of application of ITS data have been presented is Lodz – a large city in central Poland. The conducted research shows that ITS systems offer an enormous potential in providing data for spatial mobility studies. In order to fully exploit its worth, however, it is imperative to expand the research procedure by including, for instance, the results of qualitative research. Also, the interpretation of results obtained on the basis of ITS data ought to be performed with an awareness of numerous significant preliminary and simplifying assumptions.

Intelligent transport systems (ITS) are undoubtedly an opportunity for the sustainable development of smart cities today. ITS is based on advanced transport technologies that help minimise the emission of harmful substances to the environment. Smart mobility and ITS are related to the use of ICT. The implementation of technologically advanced ITS is associated with several benefits, barriers and difficulties. However, transport, ITS and smart mobility (as a component of a smart city) are indicated as the most desirable option for sustainable urban transport systems. The article aims to identify barriers related to the implementation of ITS in cities from the point of view of people responsible for the organisation of urban transport representing the local government of selected voivodship cities in Poland. The goal formulated in this way allowed to identify the following research question: what are the problems and barriers of implementing ITS in the city from the local government’s perspective? To achieve the paper’s aim, the author based their analysis on a qualitative technique of collecting empirical data. Ten individual in-depth interviews were conducted with representatives of local governments (vice-mayors and members of urban transport organisers) in voivodship cities, which represented six Polish macro-regions. Research results and findings indicate the main categories and subcategories of barriers related to the ITS implementation. The identified barriers are grouped into the following categories: economic, social, organisational, technological and legal. The contribution is twofold: first, in the presentation of the theoretical and practical barriers to ITS in juxtaposition; and second, in identifying the intelligent transportation impact, which affects the provision of being a smarter city. The findings can positively influence as important factors for local governments to focus on intelligent transport.

In this work we present solutions which aim at enhancement of the localization precision of the road side unit (RSU) devices which will participate in vehicle-to-infrastructure (V2I) communication in future autonomous driving and intelligent transportation systems (ITS). Currently used localization techniques suffer from limited accuracy which is due to various factors, including noise, delays caused by environmental conditions (e.g. temperature variation) and differences in elevation between devices communicating with each other in the road environment. In case of application of the ITS, these factors can be the source of significant discrepancies between real positions of the RSUs and their estimated values provided by the V2I system. The proposed techniques, based on various approximation techniques, as well as linear and nonlinear filters, allow to improve the localization accuracy, reducing the positioning errors by more than 90%.

Problematyka analizy niezawodnościowo-eksploatacyjnej układów zasilania stosowanych w inteligentnych systemach transportowych (ITS) jest niezwykle istotna z punktu widzenia zapewnienia bezpieczeństwa ruchu. Stosowanie w systemach ITS zaawansowanych urządzeń elektronicznych wymaga zasilania ich z odpowiednio zaprojektowanych układów zasilania. Aby zapewnić ciągłość działania urządzeń elektronicznych stosuje się najczęściej zasilanie podstawowe i rezerwowe. Powinny one cechować się określonymi wartościami wskaźników niezawodnościowych i eksploatacyjnych. Dlatego też został opracowany model niezawodnościowo-eksploatacyjny układu zasilania z uwzględnieniem odnawialnych źródeł energii (OZE), jaki jest m.in. stosowany w inteligentnych systemach transportowych. Pozwoliło to na uzyskanie zależności umożliwiających wyznaczenie wartości prawdopodobieństw przebywania układu zasilania zastosowanego w inteligentnym systemie transportowym w określonych stanach niezawodnościowo-eksploatacyjnych.

The problem of reliability and exploitation analysis of power systems used in intelligent transport systems (ITS) is extremely important from the point of view of ensuring the traffic safety. The use of advanced electronic devices in ITS systems requires their power supply from properly designed power systems. To ensure the continuity of operation of electronic devices, the basic and backup power supply are most often used. They should have specific values of reliability and performance indicators. Therefore, a reliability and exploitation model of the power system has been developed, taking into account renewable energy sources (RES), such as used in intelligent transport systems. This allowed to obtain dependencies engabling to determine the probability of staying of the power system used in the intelligent transport system in the specified reliability and exploitation states.

Mobility supported via transportation processes are the engine to economic growth of any country. Unfortunately, the existing infrastructure cannot keep up with both growth of population and people mobility, especially in the developing countries. One of the main problem in transportation processes in Africa are accidents caused among others by reckless driving, fatigue, and illegal overloading, as well as poor transportation infrastructure. To improve transportation-oriented safety and drastically reduce transport based accidents and the unnecessary loss of lives are the main today important goal. Can this goal be achieved using telematics? Telematics is a fast-growing industry and it is interesting for various applications and places around the world. The subject of the article is the concept of transport telematics system and its introduction on the example of Burundi. In most cases, intelligent transport system applications in Africa are focused on: traffic monitoring using CCTV cameras, automatic number plate recognition systems, automatic vehicle location systems, and variable traffic management systems.

During the previous EU financial perspective (2007 - 2013), we observed an intensification of the development of transport management systems using ITS services in Polish cities. One of the biggest territorially and functionally system is Tri-city TRISTAR system, the implementation of which was completed in 2015. The concept of the TRISTAR system and its architecture was developed in the years 2002-2007. Currently, we can observe the intensification of the development of C-ITS services, allowing for the exchange of information between the vehicle and the infrastructure or other vehicles. The existing transport management systems were not prepared, e.g. to communicate with vehicles, and use of Floating Car Data. For this reason, it is necessary to verify the architecture of the systems and indicate the directions of development, allowing them to adapt to the current state of technology and new ITS services. The article presents directions for the development of the TRISTAR system in functional, physical and logical terms. Directions of activities will be indicated to allow the system to be adapted to provide C-ITS services.
