  - Archives of Transport System Telematics - Rok 2018

  During the previous EU financial perspective (2007 - 2013), we observed an intensification of the evelopment 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...

  - Archives of Transport System Telematics - Rok 2018

  Over the past years, the role of inland waterway transport has increased compared to other modes of transport. The increasing intensity of the inland vessel traffic significantly affects the safety of navigation. The article analyses the main causes of accidents and incidents that occurred on the Odra Waterway and Lower Vistula. The authors have classified those accidents and suggested possible directions for the development of...

• Design of radio communication systems for unmanned transport applications

  Publikacja

  • S. Gajewski

  - Archives of Transport System Telematics - Rok 2016

  In the paper the principle of OFDMA-based radio communication systems design for unmanned transport applications is presented. The concept of system radio interface is analysed and its basic parameters proposal are considered. In the last part of the paper some air interface characteristics useful for optimization of throughput and system capacity are considered.

• The structure of the data flow in integrated urban traffic management systems – the case of TRISTAR system

  Publikacja

  • J. Oskarbski
  • M. Zawisza
  • K. Żarski

  - Archives of Transport System Telematics - Rok 2016

  The purpose of the article is to offer some insight into the data flow architecture in the Tri-City’s integrated traffic management system called TRISTAR. To that end selected elements of TRISTAR are identified and described as well as the structure for collecting and exchanging data within different sub-systems. Finally, the article highlights how the TRISTAR system can be extended by adding new elements and modules.

• Road safety information system in Poland - supporting tools and their development

  Publikacja

  • J. Żukowska
  • M. Budzyński

  - Archives of Transport System Telematics - Rok 2015

  As a signatory to the UN Declaration on road safety and member of the EU, Poland has an obligation to comply with relevant EU policies and in particular to halve the overall number of road deaths by 2020. To monitor the progress in reaching the targets, the road safety situation must be evaluated and its processes understood. For this purpose regional and national road safety observatories were launched in Poland, which triggered...

• Cognitive network model dedicated to transport system telematics

  Publikacja

  • M. Gajewska

  - Archives of Transport System Telematics - Rok 2014

  The paper defines the concept of cognitive radio, in the context of transport systems, with particular emphasis on modern ecological concept of “green cognitive radio”. In addition, in the paper a modified cognitive network model dedicated to transport system telematics is proposed and presented. Algorithms to support the functioning of the cognitive radio are discussed. Sensors necessary to use the network to support cognitive...

• Efficiency of the Use of LTE System Radio Resources in Highway Transport Enironment

  Publikacja

  • S. Gajewski

  - Archives of Transport System Telematics - Rok 2014

  The paper describes the problem of analysis of throughput-coverage characteristics of the LTE system. Simulation results of the efficiency of the use of LTE radio resources are presented. Simulation studies on the basis of original model of the LTE network simulator were carried out. In addition, the evaluation of throughput for a single connection, and available capacity were evaluated in the context of the use of the same...

• Study of data scheduling methods in the WiMAX Mobile metropolitan area networks

  Publikacja

  • M. Sokół

  - Archives of Transport System Telematics - Rok 2014

  The paper discusses basic assumptions of the WiMAX Mobile system. It also presents and analyses the results of simulation tests run for selected data scheduling methods and subcarrier allocation. Based on the test results, the authors have prepared a comparative analysis of two popular data scheduling methods, i.e. WRR and PF, and their own method CDFQ which uses information about the current channel situation for the queuing processes...
