Embodiment Construction

[0021] Embodiments of the present invention will be described below using the drawings. figure 1 It is a block diagram showing a schematic configuration of a route guidance system 100 according to an embodiment of the present invention. figure 1 The route guidance system 100 shown includes a surrounding monitoring device 2, installed in a vehicle ( figure 1 The navigation devices 3 of the vehicles A and B) and the traffic information center 1 installed outside the vehicles.

[0022] In addition, in figure 1 In , a configuration including a plurality of navigation devices 3 is shown in the route guidance system 100, but it is not necessarily limited thereto. The navigation device 3 may be configured to include only one in the route guidance system 100 , or may be configured to include three or more in the route guidance system 100 . However, below, for the sake of convenience, the description will be continued as a system including two navigation devices 3 installed in the v...

Abstract

The invention discloses route search devices (3, 5), and a route guiding system (100). The route search devices or the route guiding system is provided with: road barrier type determination parts (47, 53) determining whether a road occupant as a road barrier except a parking vehicle exists in a road zone corresponding to a link based on travel-related information comprising information of road conditions of road where the vehicle passes; and cost determination parts (47, 53) determining link cost of the link based on determining results of the road barrier type determination parts (47, 53). The route search devices and the route guiding system in the invention can prompt with high precision a guiding route for smoother travel.

Description

technical field [0001] The present invention relates to a route search device and a route guidance system. Background technique [0002] Conventionally, a navigation device is known as a device that guides a user to a predetermined destination or displays an arbitrary map. Generally, in the above-mentioned navigation device, map data is read from a recording medium such as a CD-ROM using the traveling speed, traveling direction, and current position information of the vehicle, etc., and a map near the current position is displayed on a liquid crystal monitor or the like, and , to search for the guidance route from the specified departure point to the specified destination, and display the current position and the guidance route on the map screen. [0003] In addition, in recent years, when searching for a guidance route, there has been known a technique of preferentially selecting a detour route that avoids traffic congestion based on traffic information sent from a traffic...
