Abstract: Data pertaining to at least one user-specific color value can be accessed for output of at least one of red light, green light, and blue light, and images can be presented on a display based at least in part on the at least one user-specific color value.

Abstract: In one aspect, devices and methods are disclosed for accessing data pertaining to at least one user-specific color value for output of at least one of red light, green light, and blue light, and presenting images on a display based at least in part on the at least one user-specific color value.

Abstract: Provided is a traffic congestion prediction method which is able to perform a prediction process using floating information with higher accuracy. The traffic congestion prediction method includes: a step of receiving information by a prediction device; a step of predicting a route of each floating car based on the current position information and destination information received; a step of calculating, for the each floating car, a first passing time group which is a set of respective passing times at a plurality of predetermined spots on the route predicted; a step of calculating the number of existing floating cars per link based on the first passing time group, if any of a plurality of floating cars exists on the link at a predetermined time; and a step of calculating a second passing time group by use of the number of existing floating cars and a predetermined calculation technique.

Abstract: A traffic data prediction device includes an original link traffic data storage unit (103) for storing traffic data per original link as a predetermined road link, an extended link generation unit (104) for generating an extended link from the original links, and an extended link traffic data prediction unit (108) for predicting traffic data per extended link generated in the extended link generation unit (104) by use of traffic data per original link. The extended link generation unit (104) decides the original links for generating the extended link based on data indicating a predictive accuracy of traffic data in a combined link combining the selected original links, and generates the extended link made of the decided original links as elements.

Abstract: An information provision apparatus of the present invention includes a stop detector to detect a stop of a vehicle; a display unit to display various information; and a control unit to control the display unit to display a plurality of display contents in a manner that two successive contents of information differ with each other while the vehicle is standing at the temporal stop. When the vehicle is caught in a traffic congestion to stop temporarily, the driver of the vehicle is entertained by plural contents of the information appearing on the display unit for his/her diversion.

Abstract: A technique to provide an information-sharing system and the like is disclosed. According to this technique, there are provided an on-board information terminal to transmit one or more types of information among a vehicle information relating to user's own vehicle and on-board program information to acquire shared information, an area information acquiring system for acquiring area information, and an information-sharing server for calculating time function existing quantity based on time function according to one or more types of information among vehicle information and area information, calculates time function transmission quantity based on time function including the calculated time function existing quantity, arranges the calculated time function existing quantity and the time function transmission quantity to a corresponding position on a map, attaches the map information to the on-board program information, and transmits it to the on-board information terminal.
