About C2X/V2X

C2X is the generic term to describe the communication technologies in the automotive domain which enable cars and infrastructure to talk each other.

C2X enables safer driving assistance since it allows to analyze surrounding information from other vehicles like position, speed, car control information, etc.
and infrastructure information, e.g. traffic light, highway regulation, traffic information, etc.

This product meets eight criteria, energy conservation, resources saving, reusability, etc, defined by Hitachi Group's DfE (Design for Environment) Assessment.

C2X Middleware Platform enables green and safer driving assistance to analyze in real-time surrounding information leading to the traffic reduction.
