Most severe accidents occur because

• Misjudge the speed of other vehicles
• Misjudge situations at intersections
• Speeding vehicles noticed late due to buildings/obstacles

Why V2X?

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

Cost

• Embedded vehicle

technology

• Infrastructure

Inter-

• perability
• War of standards

leads to interoperability issues. Need standardization

Certification

• Competent &

Stringent certification mechanism required

Security

• Wireless

communication environment poses security threats & fool proof security mechanisms required
