Requirement Collection
Current version of
FRAME architecture
FRAME: European Framework
Architecture for ITS deployment in the
21st Century
• Project founded by EC as part of the
5th Framework program
• FRAME ’s focus was on process and
user needs, co-operative systems
were not covered.
• FRAME already defined a lot of user
needs / requirements!

Station-Internal Interfaces
Functionalities of an ITS station might be divided to several physical
devices
Selection of a suitable interface between the devices
e. g. Ethernet, USB
Number of devices is an implementation issue and might be influenced
by several aspects
e. g. one application unit and one communication unit
e. g. an vehicle manufacturer specific gateway to the vehicle data
e. g. cost, in-vehicle architecture, project organization
ITS Station Management handles the devices and their interaction

Outlook
COMeSafety’s European ITS Communication
Architecture is a „Living Document“
Document currently extended in PreDrive C2X Project
Close interaction with ETSI TC ITS WG 2 for future
standardization
Of course all other projects and stakeholders are
invited to contribute
