UIC Project Annual Report - ERTMS

3.7 BrakingETCSUIC code I/92/E/051Annual Report 2004 DOCUMENT CODIFICATION REV. PAGEC 15 of 21Finalisation of the ETCS FRS and SRS specifications taking the points mentioned above insection 2.3.5 into consideration, i.e. the definition of the revised braking algorithm for thewarning, service- and emergency brake curves as well as the definition of the warning curvewhen only the emergency brake is applied in the case where the service brake application willnot be implemented.The following reports will be delivered in 2005:• The DB test report,• The ČD test report,• A final report of the studies of the University of Florence,• A final version of B 126 DT 407,• The revised braking algorithms including all the braking aspects (Warning, service andEmergency curves. This is basically a deliverable of the EEIG, but financed by the UICETCS budget.It has further been decided to define safety margins per interim as “national values” which willallow Group C to continue its work.As it has been decided at the last Braking Steering Committee meeting in December 2004, bothWorking groups will continue their activities:• Group A will submit a final version of a basic model to convert λ into a speeddependent deceleration function to be introduced into the TSI at the next SteeringCommittee meeting (9 February). It shall be valid for all train configurations for whichmore detailed input parameters to use an enhanced model are not available.• Group A will further develop specific conversion models taking into account theinfluence of the brake development time and additional parameters like disk-brakedvehicles, vehicles with electromagnetic track brakes ep-brakes etc.• After having submitted the enhanced model by the middle of 2005, Group A willproduce a report containing a detailed description how the model was created,evaluated and finally improved for certain train categories.• Group C will continue its work of creating a method to use standardized safety marginsafter having defined a common safety target for all kinds of trains.• After the submission of the results, Group C will produce a report containing allinformation that led to this standardized safety model.3.8 European Railway Infrastructure Masterplan (CCS part)Fundamental to a clear perspective on ERTMS, is a good technical inventory of the currentsignalling infrastructure along the European corridors identified by UIC in consultation with CERand EIM which now are part of the TSI CCS for conventional rail and will be the starting point forthe EU deployment strategy for ERTMS.
