Towards A Versatile European Driver
Advisory System

Abstract
Pacing trains is an important part of railway operations management. It helps to
improve the resilience of a timetable to perturbation and reduces significantly
both the energy consumption and the wear-and-tear, while increasing the comfort
for passengers. Today, only a few Driver Advisory Systems (DAS) with such
abilities are already in operation on European major railways. This situation
provides great opportunity to promote a unique but flexible system, which can be
implemented and used around Europe.
The paper describes a concept for a Versatile Driver Advisory System
(VDAS). The on-board part of this system is not only fully compatible with a
European Driver Advisory System (EDAS) coming from Traffic Management
Systems (TMS) but also with other DAS (NEDAS). To ensure flexibility and
versatility, EDAS can be implemented in different ways. The use of the standard
railway radio GSM-R and the opportunity to send speed advices on the ETCSDMI
are milestones on the development of ETML, the management layer of
ERTMS.
VDAS facilitates the improvement of the operational resilience to
perturbation as well as sparing energy, offers synergy opportunities with the
ETCS On-board system and, finally, VDAS is based on EDAS which may
become a European standard.
