DESCRIPTION OF RELATED APPLICATION

The present invention is based on claiming priority of Japanese Patent Application: JP2018-032423 (filed on Feb. 26, 2018), the entire contents of the application shall be incorporated and stated in the present application by reference.

The present invention relates to a dangerous act resolution system, apparatus, method, and program.

BACKGROUND

In recent years, dangerous acts such as tailgating has become a social problem, wherein tailgating means that a driver of a following vehicle drives abnormally close to a preceding vehicle. Due to such dangerous acts, damages that a driver and a fellow passenger in a preceding vehicle suffer emotional distress and accidents are increasing. There are two types as countermeasures for dangerous acts of a following vehicle, wherein the two types are a countermeasure by an instrument such as apparatus and a countermeasure by a driver of a preceding vehicle.

As a countermeasure by the instrument such as apparatus, there is taken countermeasures such that for example, a drive recorder (camera that takes video images of a following vehicle) or a dummy camera is set up at a rear end of a vehicle, or a sticker indicating that a drive recorder is set up. However, in many cases, a driver of a following vehicle who is performing a dangerous act such as tailgating does not notice the installed drive recorder or the like, so a sufficient effect by the installed drive recorder or the like cannot be obtained.

As a countermeasure by a driver of a preceding vehicle, there are taken countermeasures such that for example, the driver tries a resolution of a situation (dangerous act) by giving way to a following vehicle due to lane change, or evacuates to a safe place and reports to the third parties such as police when the situation still does not resolve. However, in situations in which the dangerous act of the following vehicle is persistently continued, the driver of the preceding vehicle may not be able to make a calm decision, and after the preceding vehicle has been forced to stop, the driver of the preceding vehicle might go out of the vehicle and suffer damage.

There is a system such that can let a third party know the situation of the driver and the vehicle and deal with it, even if a countermeasure by an instrument such as apparatus and a countermeasure by a driver of a preceding vehicle are difficult. For example, Patent Literature (PTL) 1 discloses an emergency call system terminal apparatus and an emergency call system such that an emergency call center can grasp a situation of a user and a vehicle by image data when a situation occurs in which voice conversation is impossible.
