Information system, information processing method, and non-transitory storage medium
An information system comprises a controller which is configured to execute: acquiring a screen image of a vehicle which is traveling on a roadway, the screen image being photographed by the aid of an image pickup unit; detecting a dangerous driving state of the vehicle which is traveling, in accordance with a time course of the screen image; and displaying information in relation to the vehicle having been detected to be in the dangerous driving state on a signage apparatus.
1. An information system comprising:
a controller which includes at least one processor, the controller configured to execute:
acquiring a screen image of a vehicle which is traveling on a roadway, the screen image being photographed by aid of a camera carried on another vehicle which is traveling on the roadway;
detecting, in accordance with a time course of the screen image, a dangerous driving state of the vehicle which is traveling, the dangerous driving state being detected based on a driving action of the traveling vehicle which causes a traffic danger on the roadway;
acquiring position information at which the screen image is photographed;
extracting a signage apparatus installed in an area corresponding to the position information;
judging a degree of danger of the vehicle which is in the dangerous driving state; and
displaying information in relation to the vehicle having been detected to be in the dangerous driving state on the extracted signage apparatus such that the information in relation to the vehicle having been detected to be in the dangerous driving state is (i) displayed so as to interrupt currently displayed content on the signage apparatus, in response to judging the degree of danger is a first degree of danger, and (ii) displayed after termination of the currently displayed content on the signage apparatus without interruption, in response to judging the degree of danger is a second degree of danger, the first degree of danger being greater than the second degree of danger.
2. The information system according to claim 1 , wherein the controller further executes detecting the dangerous driving state from at least one piece of information of: a speed of the vehicle, an acceleration, a distance between the vehicle and the other vehicle, the other vehicle traveling ahead of or behind the vehicle, an attitude of the vehicle, a frequency of lane change, and presence or absence of traveling in a traveling restricted area.
3. An information processing method causing a computer to execute:
a step of acquiring a screen image of a vehicle which is traveling on a roadway, the screen image being photographed by aid of a camera carried on another vehicle which is traveling on the roadway;
a step of detecting, in accordance with a time course of the screen image, a dangerous driving state of the vehicle which is traveling, the dangerous driving state being detected based on a driving action of the traveling vehicle which causes a traffic danger on the roadway;
a step of acquiring position information at which the screen image is photographed;
a step of extracting a signage apparatus installed in an area corresponding to the position information;
a step of judging a degree of danger of the vehicle which is in the dangerous driving state; and
a step of displaying information in relation to the vehicle having been detected to be in the dangerous driving state on the extracted signage apparatus such that the information in relation to the vehicle having been detected to be in the dangerous driving state is (i) displayed so as to interrupt currently displayed content on the signage apparatus, in response to judging the degree of danger is a first degree of danger, and (ii) displayed after termination of the currently displayed content on the signage apparatus without interruption, in response to judging the degree of danger is a second degree of danger, the first degree of danger being greater than the second degree of danger.
4. A non-transitory storage medium stored with an information processing program,
the information processing program causing a computer to execute:
a step of acquiring a screen image of a vehicle which is traveling on a roadway, the screen image being photographed by aid of a camera carried on another vehicle which is traveling on the roadway;
a step of detecting, in accordance with a time course of the screen image, a dangerous driving state of the vehicle which is traveling, the dangerous driving state being detected based on a driving action of the traveling vehicle which causes a traffic danger on the roadway;
a step of acquiring position information at which the screen image is photographed;
a step of extracting a signage apparatus installed in an area corresponding to the position information;
a step of judging a degree of danger of the vehicle which is in the dangerous driving state; and
a step of displaying information in relation to the vehicle having been detected to be in the dangerous driving state on the extracted signage apparatus such that the information in relation to the vehicle having been detected to be in the dangerous driving state is (i) displayed so as to interrupt currently displayed content on the signage apparatus, in response to judging the degree of danger is a first degree of danger, and (ii) displayed after termination of the currently displayed content on the signage apparatus without interruption, in response to judging the degree of danger is a second degree of danger, the first degree of danger being greater than the second degree of danger.
