no. 2 Embodiment approach

[0081] Next, a second embodiment embodying the present invention will be described with reference to FIGS. 10 to 14 . In addition, since the second embodiment is only a structure in which the generation method of the time slice width data 31 and the data transmission method are added to the first embodiment, only the differences will be described, and other descriptions will be omitted.

[0082]As shown in FIG. 10 , the data statistics system 70 as a route guidance system has a statistics server 71 as a statistics processing server that performs statistical processing on VICS signals and probe information. The statistical server 71 is connected so as to receive various data from the beacon device 72 or the base station 73 , and is connected so as to perform two-way transmission and reception of data with the navigation device 1 mounted on the car C. The statistics server 71 receives probe data Pr as probe information and VICS data Vc as road traffic information from each of th...

Abstract

Using a slice width data base that stores slice width data in which distance ranges where a vehicle will be within specified times are predicted for individual zones and individual time periods, a navigation system defines ring-shaped circular areas, which are centered around a current host vehicle position, in a temporal sequence that uses the current time as a reference. Also, based on traffic data for individual meshes and individual time periods, the navigation system searches for a recommended route from the current host vehicle position to a destination, using a traffic data base that stores traffic data that is created for individual links and using traffic data for time periods that correspond to individual circular areas in which the links are located.

Description

technical field [0001] The invention relates to a route search method, a route navigation system, a navigation device and a statistical processing server. Background technique [0002] In recent years, in order to realize the smooth driving of automobiles, the development of Intelligent Transport System (Intelligent Transport System) has been promoted. One of these areas of development is the intelligence of navigation systems. As one example, there is a navigation device equipped with a VICS (Vehicle Information and Communication System) function. This navigation device receives a beacon, uses traffic congestion information transmitted by FM multicast, and performs route guidance for avoiding the currently occurring traffic congestion. [0003] In addition, Patent Document 1 discloses a navigation device that stores statistical information stored for each mesh area of ​​a divided national map, and searches for a recommended route using the statistical information. Statis...
