High data rate transmissions for high speed trains, dream or reality ? : technical state of the art and user requirements : train-IPSAT Project-WP1 PREDIT 3-CALFRANCE

Today the key challenge for sustainable mobility
and sustainable development is to reduce the
impact of transport on the physical, social and
human environment. Promoting a set of solutions
that aims to optimize the use of existing infrastructures
for road and rail domains, to enhance safety
and security, to reduce exploitation and maintenance
costs and to offer new services to customers
and staff developing inter modal behavior, may
constitute an important contribution. This set of
solutions is based on political decisions, best practice
challenges and technological solutions developed
within several Intelligent Transport Systems
programs all over Europe.
In this context, new information and communication
technologies represent great opportunities
to develop Intelligent Public Transport Systems.
This sector has always been very open for new
technologies innovations but their development
and deployment require integration with existing
public transport environments. New information
and communication technologies are the keys to
optimize exploitation and maintenance costs, to
enhance the friendliness, comfort and security feeling
of public transport by offering new services to
passengers while traveling with the aim to promote
public transport use and multimodal behavior by
optimizing door-to-door mobility. Today, with the
development of "always on" behavior, customers on
board a train ask to receive while traveling the same
information they use to receive at home or at their
office. The Train-IPSAT project aims at developing
such services. This report constitutes the final
report of the work performed regarding "user requirements
analysis" and a technical state of the art on
the technologies suitable to answer the problem.
