Why V2X? Most severe accidents occur because  Misjudge the speed of other vehicles  Misjudge situations at intersections  Speeding vehicles noticed late due to buildings/obstacles Fatal accidents can be avoided using V2V or V2I communication Traffic congestion leading to increased emission, reduced fuel consumption and increased cost V2V or V2I communication can greatly improve the cooperative traffic management leading to reduction in cost Page 5
