Final Report PRE-DRIVE C2X 29.9.2010
impact assessment from the socio economic and business economics point of view.
Also realistic implementation scenarios for vehicular communication technology had
to be described. The following chapters describe the results achieved.
2.3.5.1 Demonstration and test of prototype system
Test and demonstration of PRE-DRIVE C2X use cases
Attractive C2X communication applications are the major success factor for a
common European deployment of vehicle communication. As described in the
chapters on WP4000 out of a long list of potential applications a reduced set was
selected for test, evaluation and demonstration in PRE-DRIVE C2X. These use
cases represent a feasible list of first phase solutions. They have been further
developed and prepared by the partners mentioned in brackets.
Three safety related use-cases were prototypically realised:
Road works warning:
A road works cone and a communication box are placed aside road works.
Oncoming vehicles are warned of potentially dangerous situations by traffic
limitations or construction vehicles ahead. (VW, DEL)
Car breakdown warning:
A vehicle with communication unit stands besides the road having its hazard
lights switched on. A warning message is sent to oncoming vehicles . (VW)
Approaching emergency vehicle warning:
A ‘look-alike emergency vehicle’ is approaching and communicating its position
and direction. A suitable waring is displayed in the other cars. (DAI)
In the field of traffic efficiency, three related use-cases were demonstrated:
In-vehicle signage and regulatory and contextual speed limit:
A list of traffic signs and their positions and relevant directions is sent to the
vehicles by a Road Side Unit. When vehicles approach the position of the sign,
drivers are informed if their speed does not comply with the regulations. (OPEL,
HIT)
Green light information for optimized speed advisory:
A traffic light communicates its signal phase and timing to approaching vehicles
and a speed recommendation is given to the driver. (BMW, NEC)
Limited access warning:
A local Road Side Unit send a message to oncoming vehicles informing about
potential restrictions for acess to certain areas. (VOLVO, HIT)
