讲座内容：
High-speed train developments is increasingly growing, whereas the use of
high speed makes possible to bring new kind of services. Among others, time
travel decreasing leads to propose some new transnational high speed
connections for passengers. Interoperability is a key component of the
trans-national high speed railways lines. Actually, there is a lot of saved
time when no material or transfer are needed in order to gothrough a border line. Moreover,
using several dedicated technological systems in order to deal with different
technological environments introduces both an over cost and some safety
problems. The presentation provides a safety point of view of the
trans-national high speed lines developments, focusing on the operating rule
management aspects. It presents the evolution from a know-how centered approach
towards a model engineering approach for safety assessment. A French ETCS
implementation problematic will be described as an illustration.
In fact, the ERTMS specification concerns on board technological systems
and their communication with the trackside material, whereas the trackside part
of the railway system is still defined by national rules. As the railway system
as to fulfill the specification from board-side and track-side, an ERTMS
implementation in a given country leads to several issues. The first one is the
validation of operation rules with respects to all specification; the second
one is the need of safety property assessment for the considered railway
system: the several different specification sources leads to a complex
problem. Last but not least, some
national operating rules forbid some specific functioning modes or had some
constraints on some other ones… The interoperability is effective when you
perform not one but two ERTMS implementations such a way that you can make a
train cross a border. In this case, a safe way of switching from a given ERTMS
implementation to another one has to be found.
As a conclusion, the need of a productivity framework, including some
formal software tools is outlines. Modular approaches based on model
engineering are discussed.
