The concept of wireless system of threats monitoring with self-organizing network of multipurpose data transfer nodes is presented. Two practical applications of this system are also presented. The first of these is the Global Wireless Monitoring System for Containers, and the second is the Mobile Monitoring System for Gas Air Pollution Measurements. Presented practical applications of the wireless...
Project Monitor is aiming to monitor quality of Traffic Information service and in first stage is focusing on evaluation of data provided by RDS-TMC and in structured XML. We propose technical, editorial and end user quality measurements. This paper gives examples of all 3 types of quality measurements. However, technical quality must be assured before we can start with others, therefore we formulate...
The theory of evidence is widely used to model uncertainty in many applications. Representation of relationship between evidence and hypothesis space are not obvious and is to be explored in many practical cases. Evidential mappings as relationship models are sort of belief assignments. The assignments engage binary and fuzzy sets with crisp, interval and fuzzy valued masses. In all cases reasoning...
In this paper, a driving assessment mechanism based on video image sequence analysis techniques, such as traffic signs and road markings detection, and inter-vehicular distance estimation, is proposed. A smart device connected to 3G wireless networks is used to collect and send sensory information. These data are analyzed in a cloud computing infrastructure to evaluate personal driving assessment...
Varied ITS systems exist in Germany and Saxony-Anhalt as well as in other countries and Federal States for several years. In other European and international countries (e.g. USA, Austria, Switzerland, Netherlands) national ITS-Action-Plans have been developed over the last years. They define a network of responsibilities and organizational structures to ensure an efficient and sustainable use of ITS...
The implementation of the open transmission standards to railway control systems requires the estimation of Tolerable Hazard Rate corresponding to EU standards. The transmission channel must satisfy the obligatory measures related to the assigned SIL level. Both cable and wireless transmission standards must be analysed corresponding to hardware failure rates in railway control devices. The paper...
The paper presents an overview of telematic solutions applicable in urban areas. Such solutions should contribute to a significant improvement of the urban transportation, while solving the cities’ current traffic problems. A lot of isolated solutions can already be found in Polish cities; however, one must think about their propagation, preferably, in the overall (system) scale. Therefore, the most...
The paper describes the current situation in the area of European road safety and draws attention to the adverse developments in several Central European countries. It presents the approach of European SOL project in relation to the actual Slovakian national road safety plan for the period 2011 – 2020. It underlines the added value of networking and contains recommendations for building multi-stakeholder...
In Japan, taxi, bus, and cargo truck operation companies are required by law to commit to driving safety management. Driving safety management is achieved by a cyclic process consisting of collecting sensory information, assessing driving safety, and improving driving based on the results. At this time, this is performed by transport company personnel. In this paper, an architecture and its implementation...
A high number of vehicles have caused strong congestion, mainly in city centres. A sustainable development of transport contains two essential physical activities. These are a formation of the traffic flows divided into different means of transportation that cover the pro-environmental transport on one side, and an innovation technology development to reduce the negative results of transportation...
This paper deals with the issue of sparse practical use of ITS architecture. Various approaches to ITS architecture in the world have been studied to capture the missing concepts and proposition has been made how to evolve with the Czech ITS architecture from just a research topic into real world praxis. The proposal is based on four different levels. First is the Organization that shall be accomplished...
The diagnosing of combustion engines with vibration methods is especially difficult due to the presence of multiple sources of vibration interfering with the symptoms of damages. The diagnosing of engines with vibro-acoustic methods is difficult also due to the necessity to analyse non-stationary and transient signals. Various methods for selection of usable signal are utilised in the diagnosing process...
Currently applied on-board diagnostic systems enable to find a simple defect if it exceeds the boundary values. If the damage does not exceed such values, measured with the use of intermediate values, which are the criteria for the assessment of exhaust fumes emission, such damage may remain unidentified by the imperfect model of the system. Preliminary tests show that some mechanical damages even...
It is commonly known that the main entity that causes accidents on level crossings is a user of the level crossings. User’s behaviour in the area of the level crossing heavily depends on the type of its protection. According to the Slovak level crossings statistics performed by the Slovak Rails, the “most dangerous” crossings are the ones equipped with a level crossing signalling system and an optical...
The paper deals with the problems of safety evaluation of a combined system, which consists of the cryptography and the safety codes applied in the safety communication layer within a safety-related system. In most cases the cryptography codes are combined with the safety codes which increase the performance of the cryptography system. In these applications it is very important to realise the optimisation...
Climatologists forecast drier summers and more humid winters in Germany and Central Europe over the next few decades. If incidents such as storms, thunderstorms or floods increase, then the consequences on traffic, the economy and the mobility of people will also increase. Furthermore, coping with climate changes and protecting the environment plays a more and more significant role. New environmental...
One of Information and Communication Technologies (ICT) benefits for the society are Intelligent Transport Systems (ITS), which make transport more efficient, faster, easier and reliable. Nowadays one of the most important aims of ITS is that these systems must become faster commonly used. Internet services are one of such solutions, cloud computing services, in particular. Generally the cloud computing...
e-Navigation is a concept being developed under the auspices of the United Nations International Maritime Organization (IMO) to bring about increased safety and security in commercial shipping through better organisation of data on ships and onshore, and better data exchange and communication between the two. The IHO is involved in the development of the e-Navigation concept to ensure that any underpinning...
This article presents several examples of Intelligent Transport Systems (ITS) with special attention paid to systems supporting the development of public transport in the area of the Metropolitan Association of Upper Silesia (Polish Górnośląski Związek Metropolitarny - GZM). The GZM is an inter-commune association of a group of cities lying within the area of the Metropolitan Association of Upper...
