The present invention provides a communication and analysis system that can manage data operations with a vehicle centric system with a planned route path. A vehicle that is in a communications link with a network can also manage its activities based on real time, historical and predictive knowledge, without having this all knowledge processing on board. Such data processing would include a cluster analysis of geo-spatial, internal functions and operator specific requirements. The rule based system would also incorporate the use patterns of a specific vehicle, or a specific user. A vehicle operator or vehicle multiple operators could share or upload information that would assist with efficient data processing and display, including fuel conservation and time management. Cluster weighting patterns can be assigned based on activities as efficient operation, safe travel and navigation.
