Opis:
Nowadays operated telematics systems offer a large collection of different types of services requiring an effective transmission of data in complex structures. It is possible by the implementation of the present network solutions for the future of telecommunications and information technology. A high level of requirements for the quick access to transport resources and databases impose the necessity of making a number of processing operations information in a short time. Single computing machines are not able to do that. Therefore, the dynamic evolution is observed to combine the processing power of cloud computing. The advantage of this solution is a fulfillment of the requirements of security, reliability and quality while reducing costs. The authors of the article presented the concept of the use of private cloud for handling traffic between major railway hubs. Basis for this is representative model CC called „infrastructure as a service” designed for heterogeneous structures.

Opis:
The process of monitoring vehicle traffic and detecting traffic incidents and traffic obstructions requires access to information from sensors located at various points of monitoring and data acquisition systems constituting elements of contemporary Intelligent Transportation Systems (ITS). Unmanned aerial vehicles (UAVs) are increasingly becoming an element of ITS used in reconnaissance, preventive or rescue operations. Ensuring the efficiency of transportation in conditions of increased traffic requires providing users with multimedia information about: meteorological conditions prevailing on roads, traffic, current events and difficulties, and information on the availability of parking spaces. In each of the mentioned cases, the reliability and quality of information provided with the use of UAVs is an extremely important issue. Therefore, the provision of video surveillance services with a predictable level of quality and reliability is an important challenge for UAVs practical implementations. Thus, the fundamental research problem considered in the publication is the analysis of the impact of environmental and technical parameters on the quality and reliability of the UAVs video monitoring service provided in a real operating environment.

Opis:
The perspective of use the Bring Your Own Device (BYOD) model in telematics environment which ensure a reliable access to network resources is presented in the paper. The BYOD model is a future-proof solution which applies in areas related to database systems. It provides the user wireless access with the use of 802.11n/ac/d standard, mobile access via WiMax-2 or LTE-A networks and wired with the use of Gigabit Ethernet technology. The research network which reflects the events representative for the telematics environment was established for the verification of functional capabilities of BYOD model. Services that offer a user the synchronization of files between mobile terminals and data server were implemented in testbed. A detailed set of test scenarios and criteria for assessment of the declared properties model BYOD were also defined. The article presents the results of research that confirm the use of this type of networking solutions for mobile and reliable access to data in a telematics environment.

Opis:
Process of ensuring the security of citizens, objects and material goods requires access to the information from sensors located in diff erent points of monitoring and data acquisition systems. Th ey are a widely used in administration of carfleet or the visualization of selected functions of transport processes. However, transmission of data from multiple video sensors may lead to the degradation of video quality and even to lack of identification capabilities. As a result, the overall service reliability can be decreased. The process of the system exploitation can determine the reliability of the video monitoring services as well. This process includes the technical object (hardware and soft ware) and the man (operator) who exploits the system under certain environmental conditions (external and internal) and represents so called antropo-technical approach in which the operating requirements are taken into consideration (particularly related to reliability). The paper presents components elaborated for maintenance of reliable video monitoring services as well as the results of selected tests showing its efficiency. Proposition of comprehensive metrics for assessing the reliability of exploitation of video monitoring system, which takes into account antropo-technical approach is presented as well.

Opis:
Along with the evolution of our civilization is increasing demand for faster and cheaper transport, both from the point of view of trade and normal movement of people. In the case of trade most often we are dealing with the transport of the freight traffic, where the goods are not carrying by one type of transport. In this type of carriage time between transhipments on exchange stations plays an important role. The correct use of modern ICT (information and communication technologies), both wired and wireless for control loads, vehicles and carriers can significantly reduce total transport time and costs. Additional monitoring of the status of land units’ drivers allows increasing the security and the reliability to wirelessly check the content and status of the load increases the reliability of the correct transport. Therefore, this article presents the use of modern wireless technologies (LTE-A, 802.11ac) and backbones of public networks (1…100 GbE) on the exchange stations.
