Future Roadway Networks Will Provide Many New Services and Create New Benefits: Greater Visibility
A Service Example
New traffic jam navigation service may tap the power of a social group
•Mobile micro cloud technology will offers ample storage for massive recent map data, community data and a variety of new network delivered services which improve the driving experience
•Rerouting of daily commute traffic jams are a common routing challenge for vehicle systems
•V2v to communications can allow traffic situation and successful routing data to be efficiently shared among participating vehicles.
