Abstract: A vehicle control device has a processor configured to calculate an average speed of a vehicle traveling in a traffic lane and another vehicle in a predetermined range from the vehicle, for each of multiple traffic lanes of a traveling road on which the vehicle is traveling, as a traffic lane average speed, to determine whether the traffic lanes are congested based on the traffic lane average speed for each of the multiple traffic lanes of the traveling road and to estimate whether the traveling road as a whole is congested based on a proportion of traffic lanes of the traveling road that are congested, and to decide to drive the vehicle by automatic control when the traveling road as a whole is congested.

Abstract: A travel controller of a vehicle that can travel on a road under autonomous driving control detecting two-wheelers, including bicycles, located in surroundings of the vehicle from surrounding data representing the surroundings of the vehicle generated by a surrounding sensor mounted on the vehicle, determining whether a target road on which the vehicle was traveling when the surrounding data in which a two-wheeler was detected was generated is a shared road on which travel by bicycles is permitted, when it is determined that the target road is a shared road, notifying a driver of the vehicle of a transition demand demanding transition in control of the vehicle from autonomous driving control to manual driving control requiring driving operations by the driver of the vehicle, and when it is determined that the target road is not a shared road, not notifying the driver of the transition demand.

Abstract: The present invention relates to a linear lighting system with a linear light source. According to the invention, all the effective light around the optical axis emitted from the linear light source is introduced to a concave reflector so that the illumination is carried out only with the reflected light. The reflected light is controlled to be a converging or parallel beam of light so that a desired area is illuminated and the luminance is increased. In a mode of the invention, a cylindrical concave reflector 2 whose section taken vertical to a linear light source 1 is a part of an ellipse 2e having a first focus F1 at the linear light source 1 and a second focus F2 at an irradiation plane 3 (irradiation target point). The part of the ellipse covers an effective emission angle 2&thgr; of the linear light source 1, and a reflected light produced at the part from a light within the effective emission angle 2&thgr; is free of obstruction by the linear light source 1.
