A method for controlling a flow of traffic on a roundabout, wherein the flow of traffic is controlled by a traffic control unit by which road users that have entered the roundabout and/or are approaching the roundabout in order to enter it are networked in a network and communicate by way of messages, and wherein, in order to enter, a road user transmits a message containing a request to the traffic control unit provides for entry by the respective road user to be preceded by the flow of traffic that is on the roundabout being determined on the basis of the messages, wherein a message containing a control signal is generated for the respective entering road user in order to communicate whether and/or along which route the road user can travel on the roundabout.

The control apparatus (200) is an apparatus that controls the travel of a target vehicle (10). The control apparatus (200) detects a partial object (20) using a sensor. The partial object (20) is a part of an object riding on the target vehicle (10) and is jutting outside the target vehicle (10). Furthermore, the control apparatus (200) outputs information (travel information) relating to travel of the target vehicle (10) based on the detected partial object (20). For example, the travel information is control information for travel control of the target vehicle (10) and notification information indicating information relating to the partial object (20).

A system for facilitating communication in regard to a user in labor may include a first electronic device associated with the user, a set of second electronic devices associated with emergency contacts, and a server. The server may be configured to retrieve coordinates of a predetermined location, a current position of the user, and vehicle information corresponding to a vehicle in which the user is traveling to the predetermined location. The server may transmit a command to activate an electronic sign associated with the vehicle to indicate the labor status. The server may transmit a first notification including the vehicle information and an estimated time of arrival to the one or more second electronic devices. The server may determine whether the user is in an emergency state and output a second notification including information related to the emergency state to the one or more second electronic devices.

A control method for a first moving body includes: acquiring, from a second moving body, emergency information that includes information on a scheduled route on which an emergency vehicle travels in an emergency; and transmitting, by device-to-device communication, the emergency information to a third moving body that is predicted to travel on the scheduled route.

Systems and techniques are described for consuming data in an intelligent transport system. In some implementations, a system includes a display screen device and sensors. The sensors generates data describing sensor observations of a roadway at a first location and provides data describing the observations to the display screen device. The display screen device receives the data and determines an event and a type of the event. The display screen device displays second data indicative of the type of event, the second data being of a format that is consumable by a sensor on a vehicle traversing the roadway towards the first location, the sensor (i) located within a first resolution distance from the display screen device and (ii) located outside a second resolution distance of detecting the event, wherein the second data is used by an on-board processing system of the vehicle to adjust its driving behavior.

This disclosure describes systems and methods for virtual parking lot space allocation. An example method may include receiving, by a processor and from a first vehicle, sensor data relating to a first location. The example method may also include generating, by the processor and based on the sensor data, a first virtual parking space of a virtual parking location within the first location.

An information processing device includes a communication unit and a control unit. The control unit selects at least one instant message as a selected message from one or more instant messages transmitted and received between terminal devices including a first terminal device. The control unit selects the selected message based on at least one of pick-up time and drop-off time of a vehicle picking up and dropping off a first user of the first terminal device. The control unit determines evaluation of a service provided in the vehicle based on the selected message.

The present invention relates to the guidance of autonomous vehicles and in particular, relates to guiding an autonomous vehicle along a roadway by means of active devices with a system which works during normal and inclement, weather as well as under any luminous conditions, These active devices are embedded in the passive and/or active road details such as traffic signs, traffic lights, warning lights etc. These active devices provide data relating to road conditions, speed, road layout etc. as well as other information such as availability of parking spaces. Accordingly, through networks of sensors and devices the autonomous vehicle can obtain road details in real-time in any weather, illumination, visibility etc.

A method of determining whether one or more navigable elements of a navigable network within a geographic area are still affected by a precipitation weather event. A quantity parameter is associated with each segment of an electronic map representing the navigable network and indicates the amount of precipitation remaining on the navigable element or portion thereof represented by the segment. The value of the quantity parameter increases in the presence of any precipitation weather event, and decreases ac cording to a predefined function with respect to time in the absence of any such precipitation weather event. A speed of travel of one or more devices along the navigable element or portion thereof represented by a segment is determined and compared to an expected speed of travel for the segment; the value of the quantity parameter being decreased based on the comparison. The value of quantity parameter can be used to generate weather events and/or attribute the cause of a congestion event as being the precipitation weather event.
