A signal information distribution system includes: a storage unit configured to store therein a timing table including scheduled lighting intervals of the plurality of signal lights; a monitor unit configured to observe lighting and extinction of the plurality of signal lights; a generation unit configured to generate the signal information, based on an actual lighting interval, of a predetermined signal light among the plurality of signal lights, obtained from an observation result of the predetermined signal light, and on the scheduled lighting interval, of the predetermined signal light, included in the timing table; and a distribution unit configured to distribute, to the vehicles, the signal information generated by the generation unit.

Traffic signal information distribution system, and traffic signal information distribution method

A signal information distribution system is configured to distribute, to vehicles, signal information including a lighting start time and a lighting continuation interval of each of a plurality of signal lights installed at an intersection, each signal light being configured to light in a predetermined color. The system includes: a storage unit configured to store a timing table including scheduled lighting intervals of the plurality of signal lights; a monitor unit configured to observe lighting and extinction of the plurality of signal lights; a generation unit configured to generate the signal information, based on an actual lighting interval, of a predetermined signal light, obtained from an observation result of the predetermined signal light, and on the scheduled lighting interval, of the predetermined signal light, included in the timing table; and a distribution unit configured to distribute, to the vehicles, the signal information generated by the generation unit.

A device according to one aspect of the present disclosure is an on-vehicle control device configured to control a traveling speed of a vehicle including the on-vehicle control device. The on-vehicle control device includes: an acquisition unit configured to acquire a present light color of a traffic light unit installed at an intersection; a calculation unit configured to calculate an avoidance position and an avoidance speed with respect to a dilemma zone at a time when yellow light starts; and a control unit configured to execute a first deceleration process of reducing the traveling speed of the vehicle at the avoidance position to a speed equal to or lower than the avoidance speed, in a case where a present position of the vehicle is on an upstream side relative to the avoidance position and the present light color is green.
