DATEX has its roots in the first cross-border ITS applications like TMC, and to this day it supports many features of these early approaches. From the beginning it has been widely used as a basis for numerous traffic centre software developments. In 2000 two European Pre-norms were established through CEN.
Following the development of the Internet as a general information exchange platform DATEX has been migrated to use standard IT approaches and tools. The result was the publishing of the fi rst DATEX II specifi cations in 2006 with fi rst small and then large scale applications following suit.
Since the very start, DATEX has been supported by the European Commission.
From the European perspective traffic management has been seen as crucial for economic development, so a high priority has been assigned to ITS as a tool to improve the performance of the TERN. Without a harmonised approach on data modelling and data exchange, ITS will fail to meet these expectations. When considering the European ITS industry perspective harmonisation is also seen as a pre-requisite to develop and succeed on a global scale.
DATEX II has been developed to provide a standardised way of communicating and exchanging traffic information between traffic centres, service providers, other traffic operators and media partners. The specification provides for a harmonised way of exchanging data across boundaries, at a system level, to enable better management of the European road network.
