Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A signal information generation system configured to generate signal information of a signal light unit including a plurality of signal lights, each of the plurality of signal lights being configured to light in a predetermined color, the signal information being for distribution to vehicles, the system comprising: a memory device configured to store therein a timing table including scheduled lighting intervals of the plurality of signal lights; a sensor configured to observe lighting and extinction of the plurality of signal lights; and a generation processing device 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. 2. A signal information generation method for generating signal information of a signal light unit including a plurality of signal lights, each of the plurality of the signal lights being configured to light in a predetermined color, the signal information being for distribution to vehicle, the method comprising: obtaining scheduled lighting intervals of the plurality of signal lights from a timing table; observing lighting and extinction of the plurality of signal lights; and generating 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. 3. The signal information generation system according to claim 1 , further comprising a distribution processing device configured to distribute, to the vehicles, the signal information generated by the generation processing device. 4. The signal information generation method according to claim 2 , further comprising distributing the signal information to the vehicles.
