Claims (7)

1 . An information processing method to be executed by a computer configured to communicate with one or more terminal devices and one or more roadside devices, the information processing method comprising: acquiring position information of the terminal device; detecting, based on the acquired position information, that the terminal device has entered a predetermined geographical range in which the roadside device is installed; detecting whether a vehicle is present in a range of a third distance or smaller from the roadside device and/or the terminal device; and transmitting, upon detection being made that the terminal device has entered the geographical range and that no vehicle is present in the range of the third distance or smaller, instruction information to provide description about a function of the roadside device to the terminal device and/or the roadside device.
2 . The information processing method according to claim 1 , wherein the instruction information is transmitted to the terminal device upon detection that the terminal device has entered, as the geographical range, a range in which a distance from the roadside device is equal to or smaller than a first distance.
3 . The information processing method according to claim 2 , wherein the instruction information is transmitted to the roadside device upon detection that the terminal device has entered, as the geographical range, a range in which the distance from the roadside device is equal to or smaller than a second distance that is smaller than the first distance.
4 . A roadside device comprising a processor and a notification circuit, wherein the processor is configured to: acquire position information of a pedestrian; detect, based on the acquired position information, that the pedestrian has entered a predetermined geographical range in which the roadside device is installed; detect whether a vehicle is present in a range of a third distance or smaller from the roadside device and/or the pedestrian; and cause, upon detection that the pedestrian has entered the geographical range and that no vehicle is present in the range of the third distance or smaller, the notification circuit to notify the pedestrian of a function of the roadside device.
5 . An information processing method to be executed by a computer configured to communicate with a terminal device and a roadside device, the information processing method comprising: acquiring position information of the terminal device; detecting, based on the acquired position information, that the terminal device has entered a geographical range in which the roadside device is installed; detecting whether a vehicle is present in a range of a third distance or smaller from the roadside device and/or the terminal device; and transmitting an instruction to the terminal device and/or roadside device to provide description about a function of the roadside device upon detection that the terminal device is within the geographical range, wherein: the instruction is not transmitted upon detection that the vehicle is present in the range of the third distance or smaller.
6 . The information processing method according to claim 5 , wherein the instruction is transmitted to the terminal device upon detection that the terminal device has entered, as the geographical range, a range in which a distance from the roadside device is equal to or smaller than a first distance.
7 . The information processing method according to claim 6 , wherein the instruction is transmitted to the roadside device upon detection that the terminal device has entered, as the geographical range, a range in which the distance from the roadside device is equal to or smaller than a second distance that is smaller than the first distance.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Japanese Patent Application No. 2023-223087 filed on Dec. 28, 2023, incorporated herein by reference in its entirety. BACKGROUND 1. Technical Field The present disclosure relates to an information processing method and a roadside device. 2. Description of Related Art Conventionally, a technique for monitoring a vehicle with a communication function is known in the art. For example, Japanese Unexamined Patent Application Publication No. 2023-50629 (JP 2023-50629 A) discloses 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. SUMMARY There is a demand for improvement in the technique for monitoring a vehicle with a communication function. In view of such circumstances, an object of the present disclosure is to improve a technique for monitoring a vehicle with a communication function. An information processing method according to one embodiment of the present disclosure is an information processing method to be executed by a computer configured to communicate with one or more terminal devices and one or more roadside devices. The information processing method includes: acquiring position information of the terminal device; detecting, based on the acquired position information, that the terminal device has entered a predetermined geographical range in which the roadside device is installed; and transmitting, when detection is made that the terminal device has entered the geographical range, instruction information for instruction on description about a function of the roadside device to at least either of the terminal device and the roadside device. According to the embodiment of the present disclosure, the technique for monitoring a vehicle with a communication function can be improved. BRIEF DESCRIPTION OF THE DRAWINGS 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: FIG. 1 is a diagram illustrating a configuration example of an information processing system according to an embodiment of the present disclosure; FIG. 2 is a flowchart illustrating an operation example of the server device of FIG. 1; FIG. 3 is a flow chart showing an exemplary operation of the server device of FIG. 1; and FIG. 4 is a flowchart illustrating an operation example of the server device of FIG. 1. DETAILED DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present disclosure will be described below with reference to the drawings. In the drawings, parts having the same configuration or function are denoted by the same reference numerals. In the description of the present embodiment, duplicate descriptions of the same parts may be omitted or simplified as appropriate. Outline of Embodiment FIG. 1 is a diagram illustrating a configuration example of an information processing system 1 according to an embodiment of the present disclosure.
