Problems solved by technology

[0007] However, in the technology described in the above-mentioned Patent Document 1, it is necessary to add new information specifying the lane where the traffic jam occurs to the traffic jam information, and it is impossible to use the existing traffic jam information that does not include these new information. implement the invention
In addition, the traffic congestion information is made by collecting the current conditions of each road by an information center such as a VICS (registered trademark: Vehicle Information and Communication System) center, but in order to determine the lane where the traffic congestion occurs, it is necessary to It is extremely difficult to collect such detailed information from roads all over the country to identify road conditions according to lane divisions.

Abstract

Provided are a driving support device and a computer program which enable driving support which takes into account congestion on each lane even when using conventional congestion information that does not include information specifying a congested lane. More specifically, the driving support device is configured to acquire congestion information specifying a congested link which is congested, and, if the congested link is a link having at least two lanes per side and there is a branch at the end of the congested link, and if the links connected to the branch include at least one each of a link that is congested and a link that is not congested, to provide driving support in accordance with an exiting link at said branch.

Description

technical field [0001] The present invention relates to a driving assistance device and a computer program for performing driving assistance based on traffic congestion information. Background technique [0002] Conventionally, various information terminals (hereinafter referred to as navigation devices, etc.) such as navigation devices for vehicles, mobile phones, smart phones, tablet terminals, and personal computers can include map information including information on road networks and facilities. Stored in various storage devices, or downloaded from servers, etc., and provided to users. In addition, navigation devices and the like perform various kinds of driving support such as specifying the user's current position by using a current position measuring system such as GPS, providing guidance on a map, or providing guidance on a route to a destination set by the user. Search and guide. [0003] In addition, in a conventional navigation device or the like, traffic conge...
