As the vehicle travels, either on a planned destination or unguided autonomous driving, the vehicle installed with Internavi records the vehicle's GPS position and speed onto the vehicle's hard disk drive, and periodically updates to the Internavi Center Information Server. This autonomous information is then retransmitted towards other users, notifying of road conditions. Vehicles installed with previous internal maps utilizing a DVD are not given updated traffic conditions.29 March 2006 Honda's press release date Speed conditions are then displayed in three colors—red, orange and blue—to signify traffic congestion conditions, overlaid with updated VICS known conditions. This feature can be deactivated by the driver if position and speed of the individual vehicle does not want to be transmitted, however by doing so, road conditions can not be shared unless the tracking system is activated. Reports will then be limited to VICS information only. Road conditions can be specifically defined towards individual lane conditions, as opposed to general road conditions, such as to identify a traffic incident in a particular lane. As the information is stored by various contributing vehicles, congestion prediction can also be provided. Road conditions are transmitted by the VICS system, however, Internavi provides additional and more specific road and traffic conditions based on individual lane conditions provided by vehicles recording Internavi "floating car" conditions, specifying which lane and the direction of the road itself. Internavi supporting traffic information is transmitted by individual driver's cell phones, and if cellphone conditions are disrupted, the information is recorded onto the vehicles HDD, so that when cellphone reception is restored, all recorded information is then transmitted and updates are sent towards participating vehicles.
