CVIS project
The objective of the CVIS (
Cooperative Vehicle-Infrastructure System
) project
[CVI] (2006-2010) was to create a unified technical solution enabling all vehicles
and elements of infrastructure to communicate with each other in a continuous and
transparent manner, using a series of media and with the augmented environment. It
is a question of enabling a range of potential cooperative services to work on an
open application system in the vehicle and roadside equipment. To do this, it is
necessary to define and validate an open architecture and a system concept for a
certain number of cooperative applications, and to develop components which are
common to the cooperation of supporting real requests and services for the drivers,
operators, the industry and other major participants. It is necessary to deal with
aspects such as acceptance by users, the privacy and security of data as well as the
interoperability of the system, but also the induced risks, in particular for driving
and the responsibilities involved. The needs for public order, the costs, the
advantages and disadvantages and economic models are also on the agenda, as well
as the deployment strategies.
In the main aspects respectively linked to the basic technology, to the
cooperative applications involved and to the choice of test and deployment sites, the
CVIS subprojects have the objective of generating the main following results:
- a multi-channel terminal able to maintain a continuous internet connection
with all the users, including mobile telephone, the Wi-Fi network channels, infrared
over short distance, ensuring full operability in communication between different
components of the vehicle and systems of traffic management;
- an open architecture linking the system on board the vehicle and the system of
telematic services management situated at the side of the road, which must easily be
able to be updated and adjusted to enable the consideration of varied client-server
technologies. It prefigures a response to our project of dynamic roads;
- techniques for the sophisticated positioning of vehicles and the creation of
local dynamic maps, based on satellite positioning, radio triangulation and the latest
methods of referencing and localization;
- extended protocols for vehicle, road and environment monitoring enabling the
vehicles to share and verify their data with other vehicles or infrastructures which
are close by, and with a service located at the side of the road;
