Transit Vehicle Area Network Standards Migration

This project develops and provides fundamental training on a higher speed, increased bandwidth vehicle area network standard, that will allow transit agencies to integrate systems onboard transit buses. This is the second phase of a multi-phase project to migrate the Society of Automotive Engineers (SAE) J-1708 onboard bus vehicle area network communications data standard to the higher capacity and more efficient SAE J-1939 standard. The vehicle area network is an essential component of the bus system; it allows systems to connect and data to be transferred over a standard communications interface. The first phase of the project was to update the transit standard based on the heavy-duty vehicle SAE J-1939 standard. The second phase will provide outreach and support activities regarding the standard. Project is funded under the National ITS Program, administered by the Department's ITS Joint Program Office.
