The contribution describes the already performed dynamic driving tests of a high-load road vehicle and an articulated vehicle composed of a towing vehicle and a semitrailer. The driving tests consisted of standard and extreme manoeuvres what means the acceleration, the braking at variable intensity and an evasive manoeuvre. The tests were conducted at different load of the semitrailer as well as with a single towing vehicle. The three-axis accelerometer was located on the car frame and in the cockpit. The contribution as well includes the assessment of the measured data and the description of its use during the creation of a physical model of the vehicle simulator movement. An intention to simulate the movement in such a way the impacts on the driver are as real as possible in comparison to real vehicles exists, thus the vehicle can be replaced by a simulator.

A goal of this article consists in demonstrating the eCall system enhancement. We propose to enhance the system by next relevant information for emergency services - exact number of persons in a vehicle including recognising adults and children, number of disabled persons and their disability kind. Further, the system will enable to identify a driver.

The “Smart Cities” topic has recently become the topic number one in the agenda of both national and international research and development projects. This paper has been written with motivation to present various ideas of experts and professionals from an academic environment that represent different scientific fields of work such as telecommunications, control engineering, traffic engineering, information and communication technologies, etc. The authors believe that using the case of the University of Žilina (UNIZA) the multidisciplinary and synergic character of the topic may be emphasized sufficiently. Therefore a special content form of the paper has been used, based on the “question-answer” pattern. Traditionally prepared papers usually follow one of two possible lines: integration dimension - from research mono-thematically oriented on one technology only up to the fully integrated approach, or socio-technical dimension- from solution of purely technical problems up to the socio-technical perspectives and position of a human in the whole chain. This paper aims to raise a set of key questions representing the most urgent problems of today's smart city agenda and answers to them.

This paper deals with a data transfer testing and modeling in communication networks supporting energy distribution. The concept of Smart Grid, which promises highly efficient and dynamic energy systems, has to be backed by convenient communication systems. The contemporary electrical grid incorporate some form of the digital communication to be able to deliver desired availability and reliability at all levels. This means that the communication systems are inseparable from the electrical grid itself. While power-engineering uses well proven methods for the grid testing, the data networking, in this particular area, is still evolving. The paper analyses advanced methods for testing and modeling of data transfers in communication networks and presents selected practical experience.

Systems applied in the last few years for an improvement of the operation of tools ensuring the most critical functions in large cities must provide their functions exploiting various methods from the area of advanced informatics and system theory. One of the most important of them is the prediction diagnostics being a tool allowing how long particular system (or the whole smart cities system alliance) can still operate well, or when it approaches to the end of such reliable state. In this contribution the possibilities of prediction diagnostic apparatus are discussed as well as limitations coming from the fact that these systems must be very often considered as uncertain, especially if they interact with human factor.

The paper is concerned with the development of an experimental wireless sensor network for environmental and other measurements related to road-based transportation in an urban environment. Three new types of compact sensor units have been developed for use in this network. A “master” unit capable of measuring CO, NO2, SO2, VOC, dust particle (PM2.5 and PM10) and noise pollution, a “slave” unit for gathering measurements with low power requirements and a “mobile” unit for location-independent environmental measurements. An experimental network made up of master units (for pollution measurements gathering) and slave-based weather stations (for measuring dispersion conditions) is currently installed in the Spořilov district in Prague. The network is designed to provide current information about the environmental impact of roadway transportation to citizens and to the public authority.

We describe a novel computationally efficient method for the fine-grained analysis of accessibility in multimodal (urban) transport systems. In contrast to existing work, we use a full-detail representation of the transport system, including exact timetables and complete maps of road, footpath and cycleway networks, which enables more accurate accessibility assessment. Compared to existing work, our approach also calculates a wider range of location- and time-dependent transport accessibility metrics, including service frequency and the number of transfers for public transport and physical effort and elevation gain for cycling. Because it employs efficient single-origin multiple-destination shortest-path graph search techniques, our method is also faster than existing approaches relying on point-to-point search algorithms. We demonstrate our method on the city of Prague, showing the interactive frontend for location accessibility analysis as well as the application of our algorithms for comparing the city-wide transport accessibility before and after large-scale timetable change.

The paper deals with detection of clusters in data measured on a driven vehicle. Such a clustering aims at distinguishing various driving styles for eco-driving and driver assistance systems. The task is solved with the help of the application of the recursive Bayesian mixture estimation theory. The main contribution of the paper is a demonstration that real measurements with non-linear relationships between them can be approximately described by the mixture model, which is known as the universal approximation. Validation experiments are shown.

It is well known that economic growth is a key factor of air traffic growth, but another explanatory variables playing a major role in air traffic evolution are: population growth, urbanization and new middle-class emergence in developing countries. Another level of air traffic is the increasing connectivity between people and regions. At first, it can be viewed as a consequence of economic growth but it is also a facilitator: directly with the multiplication of new routes and the increasing capacity in airports which extend the supply for future journeys and indirectly by stimulating the economy through infrastructure investments and the business attract. While the world total population will increase from 7 to 8.3 billion people in 2030, the urbanization growth rate is expected to be 2% per year, representing 60% of the world population or 5 billion people in 2030. Migration is also an air traffic vector. With the globalization of the economy, more and more students feel that studying abroad is positive for their future careers. One million international students come from East Asia & Pacific area to study in North America and Western Europe, which is the number one hosting region with 2 million international. Finally, simplifications of visa policies, with visa on arrival programmes replacing the traditional visa, a form of deregulation, is also having a positive impact on air traffic growth.

In this paper we focus on the system of the spare parts distribution for authorised garages in the Czech republic and its optimization based on genetic algorithm. Real world problem of garages supply consists of the design of the optimal location of distribution depots and the design of routes that are used for everyday delivery of spare parts. Both of these sub-problems that belong to NP-hard problems are solved separately using genetic algorithm. In the facility location problem, the set of customers, set of potential locations of facilities and distances for all their combinations are given and our goal is to select location of facilities with the minimum costs based on chosen criterion. In the second part of the optimization the vehicle routing problem is solved where the goal is to determine the routes described as a sequence of customers visited on this route. Every route starts and ends in the depot and is limited by capacity of the vehicle. Homogeneous fleet was used in this problem.
