Secure, scalable networked v2x system for broadcasting real-time signal phase and timing (spat) data and other sae j2735 standard messages

A system for providing real-time broadcast of signal phase and timing (SPaT) data, comprising:

• one or more server processors;
• memories, coupled to the one or more processors, configured to store executable instructions that, when executed by the one or more server processors, cause the one or more server processors to perform operations comprising:
• receiving SPaT data from one or more traffic signal controllers in either NTCIP 1202 or SAE J2735 format;
• processing the SPaT data by converting the SPaT data into one or more different formats from the NTCIP 1202 or SAE J2735 format, wherein the processing comprises distributing a processing load across a plurality of docker containers using a grouping or clustering algorithm that accounts for a raw data arrival sequence from the traffic signal controllers;
• using a third-party security credential management system (SCMS) API, digitally signing and verifying the processed SPaT data using an IEEE 1609.2 protocol;
• determining one or more nearest intersections associated with the processed SPaT data based on geolocation data of a client device provided through a cloud-hosted REST-API;
• and
• transmitting the processed SPaT data corresponding to the one or more nearest intersections to the client device in an SAE defined format, wherein the processed SPaT data transmission is implemented over heterogeneous network links through a network comprising one or more of Ethernet, fiber, 5G, LTE, or satellite links,
• wherein one or more of the receiving, processing, verification, or transmission is provided by a cloud-hosted scalable publish-subscribe based messaging broker comprising a message queuing telemetry transport (MQTT) broker.
