• What are the ITS applications to be hosted by the ITS-Host?
• How should the Roadside ITS-S interface with sensors and traffic
signals and signs?
• How should the Roadside ITS-S interface with the Vehicle ITS
station?
Crucial questions to be answered

station?
• How should the Roadside ITS-S interface with the Personal ITS
station?
• How should the Roadside ITS-S interface with the Central ITS
station?

ITS applications
An association of two or more complementary ITS-S applications constitutes
an ITS application which provides an ITS service to a user of ITS.

• A top – down approach based on the ITS sub-
system architecture
• A detailed and unambiguous specification of
the ITS application (s) to be implemented
Some high level recommendations
Technology for a better society
• A detailed and unambiguous specification of
how each ITS application is split into ITS
station applications (an allocation of the ITS
application processes to the ITS stations)
• Interface specifications based on international
standards
