Currently, the Supporting ITS Deployment Guidelines cover three different guidelines. These are about Variable Message Signs, DATEX II and ICT Infrastructure.
Variable Message Signs
European Traffic Control Centres communicate important information concerning driver’s safety and mobility using Variable Message Signs. Most of the informative elements of such messages are shown in national languages. This fact collides with a desire for superior integration and functionality within the TERN (and beyond). The main solution is changing the principles by which VMS are currently designed. The national language should not be the main one, but rather the international picture language of road signs. Pictograms, abstract alphanumeric, international abbreviations (then text) should be the protagonists. This is the compromise of EasyWay ESG4 since 2007.
On October 5 2011, DATEX II was published as CEN/TS 16157 1-3. With this milestone reached there is now an acknowledged European Technical Specification for modelling and exchanging ITS-related information between many partners. DATEX II has been developed to provide a standardised way of communicating and exchanging traffic information between traffic centres, service providers, traffic operators and media partners. The specification provides a harmonised way of exchanging data across boundaries, at a system level, to enable better management of the European road network. DATEX II will play a strong role in the implementation of integrated ITS in Europe. DATEX II is at this time developed and maintained under the umbrella of the EasyWay project and is supported by the European Commission.
The DATEX II Deployment Guideline has been designed to describe the specific tasks of DATEX II in the framework of the EasyWay Deployment programme and the ITS directive. Other EasyWay Deployment Guidelines refer to DATEX II as a standard to be used and include information of the subset of data elements or classes to be used for a specific service (so-called profiles). All together, the guidelines form a comprehensive registry of the state of ITS development in Europe.
The scope of EasyWay is to provide Core European Services to European road users. These services are harmonized in content and functionality, but also in their availability: The road users shall be able to expect availability of a certain service in a specific road environment. In order to provide a basis for the harmonization process EasyWay needs a tool to define such environments in an agreed manner. This tool is the Operating Environments – a set of pre-defined road environments combining physical layout of the road and network typology with traffic characteristics. In essence, EasyWay has agreed on a set of 18 pre-defined Operating Environments (OE) where each OE is a combination of three criteria:
Physical characteristics – Motorways, other 3/4 lane roads or 2-lane roads
Network typology – Corridor, Network, Link or Critical spot
