Patent ID: 7561180

Claim:
A safety system for a first moving object comprising: at least one information-capturing device that obtains an infrared light which a light source of a second object, being different from the first moving object, emits onto the road surface to inform other moving objects of existence of the second object; and an attention required state determining device that (1) extracts course information on the first moving object that is one of: first course information on the first moving object that is predetermined and second course information comprising light obtained by the at least one information-capturing device which a light source on the first moving object emits onto the road surface, (2) extracts positional information on the second object from the infrared light emitted onto the road surface from the second object, and (3) determines a likelihood of collision between the first moving object and the second object based on a positional relationship between the course information on the first moving object and the positional information on the second object.
