Traffic information output device/method and traffic information distribution device/method

摘要

A traffic information distribution system (70) is composed of a distribution device (11) for synthesizing pieces of the traffic information supplied from a traffic information center (10), a output device (14) for outputting pieces of the traffic information distributed from the distribution device (11), and a data communication means (52) that is connected to the output device (14) and that can communicate with the distribution device (11) in a bidirectional manner. The distribution device (11) responds to a request signal transmitted from the output device (14) via the data communication means (52) or the like, effectively synthesizes pieces of the traffic information in consideration not only of a request made by a user, recognizability at the time of output, a state of display of a map on the display screen, and a range of the map on the display screen but also of various factors in which actual road conditions are reflected, and distributes the pieces of the traffic information that have been synthesized via the data communication means (52) or the like to the output device (14).
