Provided is a system which can reduce load on a travel controller that performs a danger avoidance operation by preliminarily detecting a significant event without increasing an amount of ITS communications, thereby providing suitable assistance for travel control of autonomous vehicles. When a vehiclepasses through a certain section of a road after an in-vehicle terminalhas detected a significant event while the vehicleis traveling in the section, the in-vehicle terminaltransmits event data (images and other information related to the event) to a roadside apparatusat an end point of the section. The roadside apparatustransmits the event data to another roadside apparatusat a start point of the section, which in turn transmits the event data to an in-vehicle device in another vehicle entering the section so that the device can perform travel control based on the event data.

Travel assistance method, road captured image collection method, and roadside device

The present invention relates to a pedestrian device and a traffic safety assistance method which can effectively and properly support pedestrian's safety confirmation by utilizing vehicle-to-pedestrian communications and an AR device. A pedestrian device of the present invention includes: an ITS communication device(pedestrian-vehicle communication device) configured to perform vehicle-to-pedestrian communications with an in-vehicle terminal; a processorconfigured to determine if there is a risk of collision based on information transmitted to and received from the in-vehicle device, and control provision of an alert to a user of the pedestrian device; and an AR displayfor displaying a virtual object overlaid on a real space which can be seen by the user, wherein the processor controls display of the virtual object (virtual terminal) on the AR display as an alert operation to provide an alert to the user.

Pedestrian device and traffic safety assistance method

The object of the present invention is to enable presentation of information on a target object (vehicle) located on a road to a pedestrian at an appropriate time and such that the information includes appropriate information for the pedestrian's statues. A pedestrian device transmits position data of a pedestrian to an in-vehicle device, which determines whether or not the pedestrian approaches a vehicle based on the position data. When determining that the pedestrian approaches the vehicle, the in-vehicle device transmits guidance direction information to the pedestrian device. The pedestrian device performs control based on the guidance direction information so as to guide the pedestrian to look toward the vehicle, and the pedestrian device acquires sight status information of the pedestrian from a wearable terminal and transmits the sight status information to the in-vehicle terminal. Then, the in-vehicle terminal determines whether or not the pedestrian sees the vehicle. When determining that the pedestrian does not see the vehicle, the in-vehicle terminal transmit alert information to the pedestrian terminal, and the pedestrian terminal performs control based on the alert information so as to provide an alert to the pedestrian.

Pedestrian device, communication device, and information distribution method

A terminal device includes: a pedestrian-to-vehicle communication device configured to communicate with an in-vehicle terminal by using a first communication method, in which direct communication is performed as pedestrian-to-vehicle communication; a wireless LAN communication device configured to communicate with the in-vehicle terminal by using a second communication method, in which indirect communication is performed via a roadside device disposed on or near a road; and a controller configured to determine whether or not the terminal device is in a risky state based on state information indicating a state of the terminal device, and select either one of the first communication method, in which direct communication is used and the second communication method, in which indirect communication is used, based on a result of the determination.

Terminal device, roadside device, communications system, and communications method

A pedestrian terminal device receives pedestrian information transmitted from another pedestrian terminal device which is present in the vicinity of the pedestrian terminal device. A location of the pedestrian terminal device is acquired, and it is determined whether or not a pedestrian who carries the pedestrian terminal device is located inside a pedestrian group based on the location of the pedestrian terminal device and a location of the other pedestrian terminal device included in the pedestrian information. When the pedestrian is located inside the pedestrian group, pedestrian-vehicle communication is stopped.

Pedestrian terminal device, vehicle-mounted terminal device, pedestrian-to-vehicle communication control device, pedestrian-to-vehicle communication system, and pedestrian-to-vehicle communication method

In order to enable a driver in driving a vehicle to quickly and assuredly recognize a pedestrian having a collision risk with the vehicle even when it is difficult for the driver to recognize the pedestrian by eyes, such as during night time, an in-vehicle terminal device is configured to: determine a collision risk based on pedestrian position information and vehicle position information; generate turn-on instruction information which, when the pedestrian is determined to have the collision risk with the vehicle, causes an indicator light carried by the pedestrian to be turned on in a prescribed light color; and transmit the turn-on instruction information to a pedestrian terminal device via pedestrian-vehicle communication, and wherein the pedestrian terminal device is configured to: receive the turn-on instruction information transmitted from the in-vehicle terminal device; and turn on the indicator light based on the turn-on instruction information.
