Service Definition

“Forecast and Real Time Event Information Services” are defined as the provision of information about both expected and unexpected events to road users on identified road segments of the TEN-T network and interfaces. This predictive or real-time information could be provided on-trip and pre-trip using different information channels, accessible by the road user via different end-user devices. The service may comprise common information as well as individual (personalised, on-demand) information.

“Events” are defined as – expected or unexpected – abnormal situations which may lead to adverse effects on the road as regards to traffic safety, efficiency and environmental effects.

Functional Requirements

Functional architecture

The function of the service is to provide forecast and real-time event information to road users either pre-trip or on-trip. This may be demand responsive or led by the information providers. In Europe, both private and public information providers are involved in this information provision (see organisational requirements).

The following figure shows the typical functional architecture of a “Forecast and Real Time Event Information Services”. The vertical lines drawn between sub-function 1, 2 and 3 show, where it is appropriate to segment the whole functionality of the service into at most three sub-functions:

Functional requirement:

• FR1: Functional decomposition into sub-functions with the provision of interfaces must be carried out to enable interoperability in cases that the service is carried out by more than one organisation

Functional Advice:

Functional decomposition is recommended in any case to be prepared to involve yet further parties as may be the case in the future
