A navigation server and the like capable of improving determination accuracy of advertisement effectiveness is provided. According to a navigation system of the present invention, it is determined whether or not one or a plurality of time in which a position of a navigation device(an user or a vehicle) at each time satisfies 'a first condition' in relationship with a position of a business operator satisfies 'a second condition' in relationship with a temporal factor with respect to business transaction of the business operator. Thereafter, according to the determination result, an interest level of the user with respect to the business operator and the like is evaluated as &#x201c;a third index value&#x201d;.

Navigation server for determining location-based advertisement effectiveness

The advancing of a game is made possible using the travel in the real world of a vehicle such as an automobile, as well as advancement of the game without entirely wasting travel of the vehicle. A game system () includes a probe device () that collects and transmits travel data of a vehicle and a game device (), in which the game device () is provided with an travel data acquisition unit () that acquires travel data from the prove device (), a distance calculation unit () that calculates a travel distance in virtual space based on the travel data thus acquired, and a display control unit () that displays a sight-seeing area unique image to a user when travelling on a route in virtual space according to the travel distance thus calculated, and as a results of this travel, reaching a set sight-seeing area.

According to a navigation server () of the present invention, in a mileage matrix containing elements which denote a mileage and are defined by respective mileage factors, a first element of the elements in the mileage matrix which is defined by recognized mileage factors is determined on the basis of the mileage of the recognized mileage of a first vehicle. A second element of the elements in the mileage matrix which is defined by unrecognized mileage factors is determined on the basis of the first element. According thereto, even when the mileage factors of a second vehicle are used to define the second element but not the first element, the previous mileage of the second vehicle can be evaluated with high accuracy in consideration of a relationship between the mileage and the mileage factors of the first vehicle estimated according to the known relationship therebetween.

Navigation server

Provided are a server, a system and a method by which a utility value of information relating to fuel efficiency of a vehicle can be improved. A fuel efficiency information management server () functions so that a driver of each vehicle or a third party is informed of a ranking corresponding to the fuel efficiency level of each vehicle, together with a travel state factor of each vehicle when the fuel efficiency is achieved, through a system of eco-information.

Disclosed is a navigation system which creates 'environment contribution information' in accordance with a deviation (&#x3b4;(k)) between the total cost (C()) of a first route (RT()) which is searched by using a traffic information indicating the amount of cost required to pass through each link and the total cost (C()) of a second route (RT()) which is searched without using the traffic information. The traffic information used in searching the first route (RT()) to a target position (TP(k)) of a vehicle () is used in searching a route to a shared target position by a navigation device ().

Navigation server and navigation system

Disclosed is a vehicle state monitoring system in which, when a vehicle () has been in a driving stopped state for a reference duration or more, a message is sent to a contact address associated with a vehicular identifier of the vehicle (). The timing for sending the message may be determined on the basis of an SOC level of a battery () identified from vehicle information or estimated on the basis of a length of a last driving duration identified from the vehicle information.
