Vehicle Communications Using a Light Signal Network

A computer system comprising:

• a processor set;
• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more storage media to cause the processor set to perform operations comprising:
• receiving vehicle light signals encoding traffic information from a source vehicle travelling on a road at a light signal device in a light signal network;
• storing the traffic information encoded in the vehicle light signals to form stored traffic information;
• and
• transmitting transmission light signals encoding the stored traffic information from the light signal network to a receiver vehicle in response to detecting the receiver vehicle traveling along the road.
