A roadside service unit, a traffic prompt device, a traffic prompt system and a traffic prompt method, relating to a field of computer technology, in particular to a field of vehicle networking and intelligent transportation technologies. The roadside service unit includes: a roadside acquisition device configured to provide traffic data; a roadside computing device communicatively connected with the roadside acquisition device, and configured to generate traffic prompt information according to the traffic data provided by the roadside acquisition device; and a roadside communication device communicatively connected with the roadside computing device, and configured to send the traffic prompt information generated by the roadside computing device to a preset area.

An optoelectronic device comprises a layer stack, which includes a carrier layer, a cover layer, and a first layer. The first layer is in particular an intermediate layer, arranged between the cover layer and the carrier layer. At least one electronic or optoelectronic element, in particular an optoelectronic light source, is arranged on the first layer and at least one layer of the layer stack and preferably all layers of the layer stack are at least partially transparent. The layer stack comprises at least one layer which comprises particles with a high thermal conductivity and/or at least one thermally conductive layer which is arranged between two adjacent layers of the layer stack.

A refueling vehicle may have a front fuel dispensing module with at least one or more hoses for dispensing fuel product from the fuel tank to an external tank. The front fuel dispensing module is located between the cab and the fuel tank containing the fuel product.

An information providing device includes a display unit configured to display information to a preset view area by emitting light, a detection unit, a first determination, a second determination unit, and a control unit configured to perform an operation control of the display unit. The display unit displays the information in a main display mode and a sub display mode having a less influence on a travelling of a nearby vehicle than the main display mode has. While the information is displayed in the main display mode, the control unit switches the main display mode to the sub display mode or stops an operation of the display unit when the first determination unit determines that the possibility of entry exceeds the threshold, or when the second determination unit determines that the nearby vehicle exists in the view area.

The embodiments of the present disclosure provide a method and an apparatus for interacting traffic information, a device and a computer-readable storage medium. The method includes: in response to a first vehicle being about to overtake a second vehicle, sending overtake-preceding indicating information to the second vehicle; detecting whether the driver of the second vehicle makes a first response to the overtake-preceding indicating information; and in response to not detecting the first response made by the driver, sending additional indication information to the second vehicle.

When information regarding a situation inside and outside a vehicle is determined to match a display change condition, a control unit (32) changes a display mode of information displayed outside the vehicle by controlling a projector device (4a) or a body light device (4b).

A light emitting system includes at least one light pipe, at least one light source disposed at least partially within an interior of the system, at least one mask, and a lens substantially enclosing the interior of the system, the at least one light pipe, and the at least one light source, the lens having an inner surface, an outer surface disposed opposite the inner surface and at least one of a continuous transparent or translucent coating on the outer surface.

A computer system identifies a service provider from a plurality of service providers to fulfill a request for a transport service from a user device of a user. The service provider operates a vehicle equipped with an indicator device. The computer system obtains an output configuration associated with the user, monitors location information of a provider device of the service provider, detects a state change of the transport service based on the location information of the provider device, and, in response to detecting the state change, communicates with the provider device to cause the indicator device to display the output configuration of the user.

Systems and methods for alerting a pedestrian of the density of automated vehicles to non-automated vehicles in an area by broadcasting a visual signal representing a group mode status of automated vehicles travelling towards or within a roadway intersection. The group mode status may be broadcast as a percentage of automated vehicles to total vehicles or can be broadcast as a ratio of automated vehicles to non-automated vehicles on an external mode indicator of a subject automated vehicle. The visual signal may be broadcast as a pattern of lighting, a change in light intensity, a change in colors or a change in text. The group mode status may also be broadcast to a pedestrian equipped with a wireless device via vehicle-to-infrastructure communications. The group status may also be broadcast to and displayed on infrastructure component, such as a street light, display post, crosswalk sign, or building display configured to receive signals.

The present invention provides an information sharing system for a vehicle. The information sharing system includes at least one first Internet of Things (IoT) device, for gathering information about the vehicle or a driver of the vehicle; and a second IoT device, for sharing the information; wherein the information comprises at least one of traffic-related information of the vehicle and emotion-related information of the driver.
