Case study 4: Rail Networks

case study 4 rail networksThe CS 4 deals with ITS application on Rail Networks. In frame of CS 4 a number of application areas and technologies are described and linked together in a matrix. Among applications following are mentioned: ADAS, AVL, Collision Avoidance, Computer Aided Dispatch (CAD), DAS, Safety Information Exchange, Transit Management, and Vehicle Diagnostics. These could be treated as boundaries of CS 4. Except the above mentioned applications the number of applications, which lies out of CS scope could be mentioned.
One of the applications which is out of CS 4 scope is connected with security on rail transport. Security on rail transport refers to the organization and the use of Security Management Systems (SMS). SMS is framework for integrating safety into day-to-day railway operations and includes safety goals and performance targets, risk assessments, responsibilities and authorities, rules and procedures, and monitoring and evaluation processes. The hardware and software used in SMS could be divided into two huge groups on-board components and units located outside of the train. Main of them could be mentioned here: Surveillance Camera, Emergency Call Points, Intrusion Detection, Access Control (badge reader), Sprinklers, Smoke Detector, Public Address, Ventilation & Smoke Extraction, Platform Track Intrusion Detection System, Platform Screen Doors, TFT LCD Display, Wireless Communications (secure radio).
Another application which is out of the frame of this CS 4 is connected to the interaction of railway with road infrastructure (Rail-Highway Grade Crossings). In order to support interaction between rail and road infrastructure a number of system and technologies could be used for example: Detect the presence and length of a train through an Advanced Detection System (ADS); Communicate and process information about a train to signal controls and motorists through an ATIS; Modify signal timing plans and encourage motorists to use alternative routes through Advanced Signal Control System (ASCS).
The third application which is out of scope of CS is connected to the interaction of railways with passengers. Mainly this application refers to Real Time Passenger Information (RTPI). This application has indirect influence on the CS theme but still could be treated as a very important point in process of transportation by railway transport. RTPI systems provide passengers with the information that they need where they need from one side, from another side it could be used as data source in scheduling and rescheduling tasks.
Another application which is connected with the CS but not covered by T-TRANS project is a Railway Signalling System. Usually this type of system is used for the control and management of train traffic by control centres. By itself Signalling Systems are also very important for Rail Yards, which are used for storing, sorting, or loading/unloading, railroad cars and/or locomotives. Large yards may have control towers, which use ICT technologies in order to do online track of operations.
The fifth application which is not in the frame of T-TRANS is connected with Emission Control Systems. The EU puts a big attention to the ecology questions and to the reduction of emissions. The railway system also is treated as one of the source of pollutions. The question is extremely important in Rail Yards, because of the high concentration of locomotives. In order to control emissions, Emission Control Systems are used to provide information about the level of emissions. Usually it is organized in form of different external detectors, which collect information about level of different substances in air. Also this question is important for underground transportation as high level of emissions is dangerous for passengers.
