Each vehicle communicates with other vehicles and assess the required data.
It is the most advanced technique implemented in ITS.
It requires very less communication with the center or infrastructure.
All vehicles will communicate with each other and decisions will be made by the
vehicle device only.
For ex, the ramp meter will work all by itself and no infrastructure device will
be required.
Some real time services cannot be provided by infrastructure.
In these cases such type of communication will be helpful.
Fig. 1 shows the collision warning principle.
Some examples are:
- Approaching vehicle warning
- Blind spot warning
- Co-operative cruise control
- Collision warning
- Lane change assistant
