Navigation information distribution systems, methods, and programs
First Claim
1. An information distribution center for use with a navigation apparatus, the navigation apparatus including a communication device that transfers a piece of vehicle position information to the information distribution center, the piece of vehicle information including a vehicle position and a time when the vehicle passes through the vehicle position, the information distribution center comprising:
- a communication device that receives pieces of vehicle position information and traffic information including congestion information and distributes a calculated congested section travel time;
a memory that stores the received pieces of vehicle position information in order of arrival; and
a controller that;
specifies a congested section based on the congestion information;
weights a first travel distance within the congested section according to the congestion information about the congested section, the first travel distance calculated based on two of the received pieces of vehicle position information received from the navigation apparatus and the congestion information about the congested section;
calculates a first travel time corresponding to the first travel distance; and
calculates the congested section travel time necessary for passing through the congested section based on the calculated first travel time.

Abstract
Navigation information distribution systems, methods, and programs transfer a piece of vehicle position information to an information distribution center every predetermined time period, the piece of vehicle information including a vehicle position and a time when the vehicle passes through the vehicle position. The systems, methods, and programs receive pieces of vehicle position information and traffic information including congestion information, store the received pieces of vehicle position information in order of arrival, and specify a congested road section on the basis of congestion information. The systems, methods, and programs assign a weight of a first travel distance within the congested road section, the weight of the first travel distance calculated on the basis of two of the received pieces of vehicle position information received from the navigation apparatus and congestion information about the congested section. The systems, methods, and programs calculate a first travel time corresponding to the first travel distance, calculate the congested section travel time necessary for passing through the congested section based on the calculated first travel time, and distribute the calculated congested section travel time to a navigation apparatus.
