PERZYŃSKI UNIVERSITY OF TECHNOLOGY AND HUMANITIES IN RADOM, Malczewskiego 29, 26-600 Radom, Poland EMAIL: [email protected] ABSTRACT Th e transport systems are now equipped with more telematics devices for improvement the functionality and safety purposes. One of the methods of evaluating telematics systems is modeling. Th e paper presents the basic model of typical land transport means (vehicle with anti-collision system, railway system) related to standard reliability model including non-safety, critical state. Th is model based on Markov processes theory may be more detailed corresponding to “telematics” control state connected with system reaction for driving improper action or device failure and activation the emergency control procedure. KEYWORDS: telematics systems, transport safety modelling, Markov processes 1. Introduction improving the safety of vehicle movements. Transport safety is one of the priorities of the Member States of the European Union. Th e Telematics, as a collection of solutions in the fi eld of computer activities of the European Commission are aimed to creating a science, teleinformation, control and management systems, is uniform and common European transport area. Th e innovation one of the tools in the management of vehicle traffi c. Th e term of strategy assumes the use of solutions based on new technologies, telematics comes from the word telematique, which was fi rst used including the European Rail Traffi c Management System (ERTMS) by Simon Nora and Alain Minc, [14]. Th e main tasks of telematics or intelligent transport systems (ITS) [4]. are shown in Fig. 1. Th e paper presents the problem of transport safety in relation to telematics systems used in road and rail transport. As a tool for evaluating telematics systems, the authors used a mathematical apparatus in the form of Markov processes. Safety was defi ned as the probability of a dangerous, catastrophic state. Of course, the number of states controlled by the telematics system and the number of catastrophic states may be greater than one, and the models proposed in the paper may additionally take into account environmental conditions, health of the operator, road characteristics, etc. Two examples were analyzed in the paper, one with a car equipped with an anti-collision system (CA), the other with a train equipped with an automatic driving control system (ETCS). Both systems show how Fig. 1. Main tasks of transport telematics [own study] introduced telematics systems can reduce the likelihood of occurrence dangerous situations, accident. Th e conclusions suggest directions for Telematics allows the introduction of optimization in the the development of telematics systems towards autonomous vehicles. management of transport and allows to increase the effi ciency of the use of transport means. Telematics is also a tool for Volume 12 • Issue 3 • September 2019 3 TELEMATICS AS A METHOD FOR IMPROVEMENT THE TRANSPORT SAFETY 2. New solutions in road and rail transport One of the elements improving the process of managing transport means is the use of modern technologies. Th e development of teleinformatics systems has permitted creating solutions that allow for safer movement of vehicles. Th e information from sensors, cameras or other vehicles and its quick processing allow the use of telematics systems in systems responsible for safety movement of vehicles. Implementation of telematics solutions in vehicles, in many cases, may exemplify an autonomous safety system and a kind of redundant system for human errors. One of the solutions used to improve transport safety is the ERTMS / ETCS railway system or the anti-collision system dedicated to road transport. 2.1 Railway system ERTMS/ETCS Fig. 2. Elements of the ETCS system [own study based on 6] In order to unify the railway traffi c control system in the European Union, a uniform ERTMS (European Rail Traffic Th e individual marks in Fig. 2 show: Management System) rail traffi c control system was developed already • 1 - driver’s interface, in the 1980s.

  • Traffic and Road Sign Recognition
    Traffic and Road Sign Recognition Hasan Fleyeh This thesis is submitted in fulfilment of the requirements of Napier University for the degree of Doctor of Philosophy July 2008 Abstract This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm. Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%.

  • International Road Signs Leaflet
    International Road Signs Leaflet Edition 2008 A Comprehensive list of unusual road signs by country © AIT-FIA Information Centre (OTA) Preface This third edition of the International Road Signs leaflet includes three new countries (Kuwait, Latvia and Slovenia) as well as a number of new unusual road signs in several countries. The publication follows a similar approach as the 2005 edition. We have tried to select the most unusual road signs among the ones which do not conform to those prescribed by international agreements, namely the Protocol on Road Signs and Signals (Geneva, 1949) and the Convention on Road Signs and Signals (Vienna, 1968). There is certainly a degree of subjectivity in our selections and we apologise for missing any signs that would have deserved to be inserted in this leaflet. But be sure we will take your remarks into consideration for future updates. We would also like to thank all the national automobile clubs for their invaluable help in the making of this publication. Whether you read it out of curiosity or because you intend to travel abroad, we hope you will enjoy using this leaflet. © AIT-FIA Information Centre (OTA) Table of content Things to know Australia Austria Belgium Brazil Canada China Czech Republic Denmark Finland France Germany Hong Kong Iceland Israel Italy Japan Kuwait Latvia Macedonia (FYROM) Malaysia Mexico Netherlands New Zealand Norway Poland Portugal Russia Slovenia South Africa Spain Sweden Switzerland Turkey United Kingdom USA Tunnel road signs in several countries © AIT-FIA Information Centre (OTA) Things to know According to international agreements: - Danger warning signs are either triangles or diamonds depending on the countries - Restrictive or prohibitory signs are usually circular with red borders.

Meeker, F. SEGD Meeker & Associates, Inc. Larchmont, NY This body of work started at this sleepy intersection off of I-84 in the state of Oregon. As part of a motorist information project for the Oregon Department of Transportation (ODOT), I was finally forced to look for the answers to questions that I had wondered for years. Why? 1) Why is the structure of this information so eclectic and seemingly dysfunctional? 2) We are taught that mixed case would be more readable (why isn’t book/magazine/newspaper text published in all upper case?); so why are conventional road guide sign destination names in all upper case letters? 3) Why is the destination name on that freeway guide sign so fat? Why does it appear that you can’t fit your finger through the center space of the small “e” and the letterforms chunk up when viewed at a distance? 2 3 A lot of information competing for your attention yet created as if it is to stand alone! And Oregon is not alone.

  • Residential Street Standards & Neighborhood Traffic Control
    Residential Street Standards & Neighborhood Traffic Control: A Survey of Cities' Practices and Public Officials' Attitudes Eran Ben-Joseph Institute of Urban and Regional Planning University of California at Berkeley Abstract The failure of the local street system to provide livability and safety in the residential environment can be seen in the application of neighborhood traffic management programs by local authorities to mitigate traffic problems. In order to further identify the extent of the conflict associated with "livability" and geometrical design of residential street, the following issues are examined: (1) Existing and proposed residential streets standards and regulations as practiced by various cities and their evaluation by public and city officials. (2) Traffic problems associated with residential streets and their mitigation through traffic management and control programs. Data are collected from Public Works and Traffic Engineering Departments of 56 Californian cities and 19 cities nation-wide. The findings show that most cities are still adhering to published street standards as recommended by different professional and federal organizations. Although some city officials see the need to amend certain aspects of their regulations and create a more flexible framework for street design, most of them believe that the current practice is satisfactory. Yet, the extant of residents' complaints about traffic problems on their streets might indicate an inconsistency between professional practice, as manifested in street design, and its actual performance as experienced by the residents. This can also be seen in the application of traffic control devices used by local authorities to mitigate these problems of which the most common are the installation of speed humps and 4-way stop signs.
