The article examines the underground passenger trains planned schedule automated construction system development stages. technical means, basic methods and information technologies applied at stages aimed its intellectualization, ways of integration into Unified vehicles control traffic intelligent on urban rail transport systems are described.
Highways are an essential component of our society because they are critical to quality of life and to local and national economies. Under good conditions, highways provide a safe and efficient route for people and goods to reach their destinations. However, as a direct consequence of their use, traffic congestion is ever-increasing, undermining the ability of highways to adequately provide an ...
In 1996, on initiative of the Swedish National Rail Administration, a research study was initiated by the department of Human Computer Interaction at Uppsala University with the aim to learn more about the problems and difficulties involved in train traffic control. As a result of this study, and the developing situation with higher speeds, more frequent traffic, and many competing train traffi...
In the United States, railways are the major means to trans-continentally move goods from ports to the various inland destinations. Due to mergers and abandonment of rail lines, there has been a reduction in the track capacity, concentrating rail traffic to fewer lines. In addition to this, booming trade with Pacific Rim nations has seen the annual trade in the Ports of Los Angeles and Long Bea...
To evaluate the quality of available evidence on the effects of environmental noise exposure on sleep a systematic review was conducted. The databases PSYCINFO, PubMed, Science Direct, Scopus, Web of Science and the TNO Repository were searched for non-laboratory studies on the effects of environmental noise on sleep with measured or predicted noise levels and published in or after the year 200...
As a sustainable means of public transport, the safety urban rail transit is significant section and highly important in development. Research on importance stations plays an role improving reliability networks. This paper proposed improved method for evaluating topology network, which was used to identify key that affect network performance. based complex theory, considering traffic characteri...
This paper presents the state of the current activities to develop a high-speed inspection system for evaluating rail defects. Since conventional contact ultrasonic techniques are speed limited, the aim was to build an automatic inspection system, which applies non-contact ultrasonic methods. An automatic Laser Ultrasonic system for Rail Inspection (LURI) has been developed and tested on a rail...
