BIM Applications for Track Maintenance

A holistic approach.   Transport infrastructure plays a vital role in our society. Deliberate harmful actions intended to damage or interrupt the use and operation of transport infrastructure can affect negatively the pursuit of economic activities, generate substantial financial losses, undermine user confidence and cause major damage to the economy.   This book answers the question of what is meant by critical transport infrastructure. Network and information systems are essential for its effective control. That is why these systems in particular need to be protected against unauthorised access. The motivation of companies and organisations to secure the critical transport infrastructure which they operate is based on a uniform legal framework imposed within the European Union.   EU legislation has to be transformed into national laws by each one of the member states. It is the ultimate goal of legislation at European level to set out an equal level of protection of consumers and businesses to cybersecurity threats. In order to do so, operators of critical transport infrastructure first of all need to be identified. These operators then need to define the requirements for protection measures, in proportion to the risks represented to their networks. Such risks need to take into account the current state of the art of cybersecurity.   Following the design paradigm of defence in depth, an effective protection of critical transport infrastructure can only be achieved with an adequate combination of technical and organisational measures, as well as the appropriate physical protection of the relevant assets.   The included e-book provides users of a device with pdf-reader (PC, tablet, smartphone) the contents of the work also electronically and with search function.

Components - Functions - Operations   This ABSTRACT represents the valid normative basis for highly automated light rail systems. The presentation is based on the author’s experience in advising transport companies and his practical work in the acceptance assessment of train protection systems for international metros and light rail vehicles.   This ABSTRACT offers you:- Definitions of automatic train control systems (CBTC)- Basic safety functions of automatic train control systems- Definition of the degree of automation of automatic train control systems- Operating modes and mode transitions of automatic train control systems- Performance criteria of automatic train control systems   Millions of people use public transport every day. Without efficient rail transport systems, the world's metropolises would face a traffic infarction every day. However, in many places the existing infrastructure is reaching the limits of its capacity. The key to increasing the efficiency of urban rail transport systems lies in automation. In recent decades, more and more cities around the world have invested in high-performance rail transport systems. For a long time, Germany has not reinvested in metro and light rail systems. The technological basis in cities is therefore often outdated and in some places has already exceeded the limits of its technical life. In some cities, transport companies will therefore renew their infrastructure over the next few years. In Germany, too, comprehensive investments in the renewal of the signalling infrastructure of metro and light rail systems are to be expected.   The included e-book provides users of a device with pdf-reader (PC, tablet, smartphone) the contents of the work also electronically and with search function.
