It should be noted that pedestrians or bicycles should not cross the road when traffic signals for pedestrians or bicycles are lit in red. A pedestrian or bicycle may cross the road when a pedestrian or bicycle traffic signal is illuminated in blue. That is, when the control program 9A receives the information indicating that the traffic signal for pedestrians or bicycles is lit in red, the control program 9A estimates that the user is not permitted to cross the road, and issues the above notification. It is determined that the road is a road to do. Further, when the control program 9A receives the information indicating that the traffic signal for pedestrians or bicycles is lit in blue, it estimates that the user is allowed to cross the road and issues the above notification. It is determined that it is not a road to do.

The processing shown in FIG. 2 is realized by the controller 10 executing the control program 9A stored in the storage 9.

As shown in FIG. 2, the controller 10 determines whether it is in a moving state (step S101).

As a result of the determination, if the controller 10 is in the moving state (step S101, Yes), the controller 10 acquires the map data corresponding to the current position of the user from the map data 9E (step S102).

Then, the controller 10 calculates the locus|trajectory of a user's movement (step S103).

Then, the controller 10 determines that the user can move the road based on the positional relationship between the position of the road on the map corresponding to the current position of the user identified from the map data acquired in step S102 and the locus of movement of the user. It is determined whether there is a sign of crossing (step S104).

As a result of the determination, when there is a sign that the user crosses the road (Yes in step S104), the controller 10 determines whether the road in which the sign of the user's crossing is detected is a road to be notified (step S105). ).

As a result of the determination, the controller 10 executes at least one of the warning notification to the user and the outside notification when the road is to be notified (step S105, Yes) (step S106). For example, the controller 10 determines that the road should be informed if the road on which the sign of crossing by the user is detected is not the pedestrian crossing, or if the road is not the pedestrian crossing and the width of the road exceeds the threshold. For example, the controller 10 determines that the road should be informed if the road on which the sign of crossing by the user is detected is not a pedestrian crossing and the width of the road exceeds the threshold. For example, the controller 10 determines that the road is not the one to be notified when the communication with the roadside device is confirmed.

Then, the controller 10 calculates the locus|trajectory of a user's movement (step S205).

Then, the controller 10 is based on the positional relationship between the position of the road on the map corresponding to the current position of the user identified from the map data acquired in step S204 and the locus of movement of the user calculated in step S205. , It is determined whether there is a sign that the user will cross the road (step S206).

As a result of the determination, when there is a sign that the user crosses the road (step S206, Yes), the controller 10 determines whether or not the road in which the sign of the crossing by the user is detected is a road to be notified (step S207). ).

As a result of the determination, the controller 10 executes at least one of the notification of the user's attention and the notification to the outside when the road is to be notified (step S207, Yes) (step S208).

Subsequently, the controller 10 determines whether to continue the processing (step S209).

As a result of the determination, the controller 10 returns to the determination of the above step S201 when continuing the process (step S209, Yes). On the contrary, if the controller 10 does not continue the process as a result of the determination (No in step S209), the controller 10 ends the process illustrated in FIG.

In the above-mentioned step S207, as a result of the judgment, the controller 10 moves to the judgment of the above-mentioned step S209, when it is not the road to be notified (step S207, No).

In step S206, if the result of the determination is that there is no sign that the user will cross the road (No in step S206), the controller 10 proceeds to the determination in step S209.

In step S203, as a result of the determination, the controller 10 proceeds to the determination in step S209 when the user's transportation means is an automobile or a train (step S203, Yes).

In the above-mentioned step S201, as a result of the judgment, the controller 10 shifts to the judgment of the above-mentioned step S209 when it is not in the moving state (step S201, No).

According to the above-described other embodiment, the smartphone 1 has a sign that the user will cross the road if the user's means of transportation is an automobile or a train, that is, if there is no fear of crossing the road. It can be controlled not to make a judgment.

In the above embodiment, when the navigation program 9B is providing route guidance information to the user, the smartphone 1 cooperates with the navigation program 9B and the trajectory of the user's movement deviates from the route corresponding to the route information. When this is detected, the acquisition interval of the user position information may be shortened. Alternatively, the smartphone 1 detects a change in the traveling direction of the user based on the detection results of the gyroscope 17 and the magnetic sensor 18, and when the traveling direction changes, shortens the acquisition interval of the position information of the user. You can In this way, the smartphone 1 can increase the prediction accuracy of the sign of road crossing by the user by grasping the user's current position in detail when the user deviates from the scheduled action.
