The present disclosure relates to information processing devices.
There has been disclosed a notification system that notifies pedestrians or vehicles other than an autonomous vehicle that is going to pass through a predetermined traffic area of whether the pedestrians or the vehicles can proceed, or alerts the pedestrians or the vehicles, according to the behavior of the autonomous vehicle (e.g., Japanese Unexamined Patent Application Publication No. 2023-050629 (JP 2023-050629 A)).
When a bus vehicle is stopped at a bus stop, a following vehicle approaching the bus vehicle from behind does not know the situation of the bus vehicle such as when the bus vehicle is going to depart the bus stop, and it is difficult for the following vehicle to determine whether to pass the bus vehicle. As a result, the following vehicle may pass the bus vehicle unsafely, which puts the bus vehicle and the following vehicle in a dangerous situation in terms of traffic safety.
In view of the above circumstances, an object of the present disclosure is to convey the situation of a bus vehicle to a following vehicle.
An information processing device according to an embodiment of the present disclosure is an information processing device including a notification unit and a control unit.
The control unit is configured to perform an operation including predicting a dwell time of a bus vehicle stopped at a bus stop, and notifying a following vehicle traveling behind the bus vehicle of information on traveling of the bus vehicle including the dwell time via the notification unit.
According to the embodiment of the present disclosure, the situation of the bus vehicle can be conveyed to the following vehicle.
Features, advantages, and technical and industrial significance of exemplary embodiments of the disclosure will be described below with reference to the accompanying drawings, in which like signs denote like elements, and wherein:
Although the bus vehicle 2 in the present embodiment is described based on being an autonomous vehicle, the bus vehicle 2 may be a bus vehicle driven by a driver. For the following vehicle 3, it is recognized that the bus vehicle driven by the driver is not forced to depart because the driver is a professional. On the other hand, there is a sense of anxiety in the following vehicle 3 that the autonomous bus vehicle may suddenly start moving. According to the present disclosure, when the bus vehicle 2 is an autonomous vehicle, the information processing device 1 eliminates the anxiety caused by the autonomous driving of the bus vehicle 2, and further makes it possible to create a sense of security of the following vehicle 3.

Hereinafter, a process executed by the information processing device 1 according to the present embodiment will be described in detail with reference to a flowchart of
In S1, the information processing device 1 predicts the dwell time of the bus vehicle 2 stopped at the bus stop. The dwell time of the bus vehicle 2 is one of the information on traveling of the bus vehicle 2. An embodiment in which the information processing device 1 predicts the dwell time of the bus vehicle 2 is as follows.
Alternatively, the control unit 11 may determine a predetermined dwell time (for example, three minutes) for the number of boarding passengers (for example, three) and a predetermined dwell time (for example, two minutes) for the number of alighting passengers (for example, three). These dwell times may be compared to determine the longer dwell time (e.g., 3 minutes) as a dwell time.
In S2, the information processing device 1 may determine a scheduled travel operation after the bus vehicle 2 departs the bus stop. The scheduled travel operation may be one piece of information on traveling of the bus vehicle 2. For example, route information may be acquired from the bus vehicle 2 or the control server 4 via the communication unit 12 to determine the scheduled travel operation of the bus vehicle 2. The determination of the scheduled travel operation of the bus vehicle 2 may be performed, for example, by determining that the bus vehicle 2 performs either a right turn or a left turn within a predetermined distance based on the acquired route information. The predetermined distance may be 500 m, long, and 1 km, for example. The information indicating the scheduled travel operation of the bus vehicle 2 may be, for example, information indicating that the bus vehicle 2 is scheduled to perform either a right turn or a left turn after starting, such as “scheduled right turn after starting”.
In S3, the information processing device 1 may determine whether the bus vehicle 2 is going to depart or continues to stop. The information may be one piece of the information on traveling of the bus vehicle 2. The information may be, for example, information indicating “departing” or “stopping” for the bus vehicle 2. An embodiment in which the information processing device 1 determines the information is as follows.
As an additional embodiment, the information processing device 1 may determine that at least one of the persons who are on or off the bus vehicle 2, or that the passenger on or off the bus vehicle 2 has been completed. The information may be one piece of the information on traveling of the bus vehicle 2. The embodiment in which the information processing device 1 determines the information may be determined in the same manner as in S3. Such information may be, for example, information indicating “getting on,” “getting off,” “getting on and off,” “getting off,” “getting on and off,” “getting on and off,” or a combination thereof.
As an additional embodiment, the information processing device 1 may determine information indicating at least one of the number of people getting on the bus vehicle 2 and the number of people getting off the bus vehicle 2. The information regarding the number of persons may be one piece of the information on traveling of the bus vehicle 2. In the embodiment in which the information processing device 1 determines the information, the control unit 11 may acquire and detect an image captured by at least one of the imaging unit 15 and the imaging unit in the bus vehicle 2, the number of people getting on the bus vehicle 2 and the number of people getting off the bus vehicle 2. Alternatively, in the case of the bus vehicle 2 in which the reservation system has been introduced, the number of passengers getting on and off the bus vehicle 2 and the number of passengers getting on and off the bus vehicle 2 may be the number of passengers getting on and off the reserved bus vehicle (the number of passengers getting on and off). The information about the number of persons may be, for example, information indicating “five boarding passengers”, “two alighting passengers” or “five boarding passengers, two alighting passengers” or the like.
In S4, the information processing device 1 notifies the following vehicle 3 traveling behind the bus vehicle 2 of information on traveling of the bus vehicle 2 via the notification unit 14. The notification by the notification unit 14 may be performed by, for example, display on a display, voice transmission by a speaker, and light transmission by a light-emitting device. An example of the notification by the information processing device 1 is as follows.
As a modification of the present embodiment, at least one of S2 and S3 is optional. That is, the information processing device 1 may not execute at least one of S2 and S3. As an additional variation of the present embodiment, the order of S3 from S1 may be interchanged.
As described above, according to the present embodiment, the operation of the control unit 11 of the information processing device 1 includes predicting the dwell time of the bus vehicle 2 that is stopped at the bus stop station, and notifying the following vehicle 3 that is traveling behind the bus vehicle 2 of information on traveling of the bus vehicle 2 including the dwell time via the notification unit 14. With this configuration, the information processing device 1 can contribute to the improvement of the traffic safety of the bus vehicle 2 and the following vehicle 3 by supporting the determination of whether or not to overtake the bus vehicle 2 or whether or not to safely overtake the bus vehicle 2 by the following vehicle 3.
Further, according to the present embodiment, the notification by the notification unit 14 is performed by displaying on the road surface. Generally, in the notification by the display, the driver of the following vehicle 3 may not be aware of the device on which the display is mounted or of the display itself. Further, the notification by the speaker is, for example, a notification by a sound such as “please be careful” or a warning sound or a warning sound, and the amount of information that can be emitted from the speaker may be limited. With the above configuration, the information processing device 1 can notify the driver of the following vehicle 3 to recognize more information than those.
Further, according to the present embodiment, the operation of the control unit 11 of the information processing device 1 includes determining the scheduled travel operation of the bus vehicle 2 after the bus vehicle 2 departed the bus stop, and the information on traveling of the bus vehicle 2 includes information indicating the scheduled travel operation. In general, since the traveling speed of the bus vehicle 2 is slow, the following vehicle 3 tries to overtake the bus vehicle 2 from the side (from the right side or from the left side). For example, the following vehicle 3 is notified of information indicating that the bus vehicle 2 is scheduled to perform either a right turn or a left turn after starting. Accordingly, it is possible to cause the following vehicle 3 to recognize at least one of the following: that the bus vehicle 2 is scheduled to perform either a right turn or a left turn immediately after starting the vehicle; and that the bus vehicle 2 will perform a lane change after starting the vehicle in order to perform either a right turn or a left turn. Accordingly, since the following vehicle 3 can assume that the bus vehicle 2 does not come from the front of the following vehicle 3 immediately after starting, it is possible to cause the following vehicle 3 to determine not to overtake the bus vehicle 2. This determination can cause the following vehicle 3 to reduce or prevent unsafe or unnecessary passing of the following vehicle 3, for example. Therefore, the information processing device 1 can contribute to further improvement in traffic safety of the bus vehicle 2 and the following vehicle 3.
Further, according to the present embodiment, the operation of the control unit 11 of the information processing device 1 includes determining whether the bus vehicle 2 is going to depart or continues to stop, and the information on traveling of the bus vehicle 2 includes the information indicating whether the bus vehicle 2 is going to depart or continues to stop. With this configuration, the information processing device 1 can notify the following vehicle 3 of the information on traveling of the bus vehicle 2 in more detail. Further, with this configuration, the information processing device 1 supports the determination of whether or not to overtake the bus vehicle 2 or whether or not to safely overtake the bus vehicle 2 by the following vehicle 3. With this configuration, the information processing device 1 can contribute to further improvement in traffic safety of the bus vehicle 2 and the following vehicle 3.
Further, according to the present embodiment, the information processing device 1 is installed by a road on which the bus vehicle 2 and the following vehicle 3 travel. With this configuration, the information processing device 1 can smoothly acquire information and smoothly cooperate with the bus vehicle 2 and the following vehicle 3.
