15. Transportation Systems Design, Inc. 14 Obtaining True Interoperability The Devil is in the Details

16. Transportation Systems Design, Inc. 15 IEEE Interoperability Issues n Existing RTVISC standards are necessary n Currently, they are not sufficient – Many still have a “performance/functional” flavor – Precise interfaces required to permit interoperability n Additional work is required by either or both: – IEEE Working Groups – L ON M ARK Interoperability Association

17. Transportation Systems Design, Inc. 16 L ON M ARK Association n Independent Association of L ON W ORKS users –Manufacturers, end-users, and integrators/car builders n Governed by industrial council n Well established interoperability guidelines –Functional Profiles –Complete interoperable specifications n Promotes L ON M ARK certified products –Existing published guidelines –Task groups make new guidelines

19. Transportation Systems Design, Inc. 18 n Process may now be “end-user” driven n TCRP Project will facilitate standardization n NYC Transit is a major standards force – Actively participates & supports IEEE standards – Mandates L ON W ORKS and L ON M ARK devices – Needs 200 subway cars/year » Until they stop running the subways in NYC What lies Ahead?

20. Transportation Systems Design, Inc. 19 Summary n Communications Interoperability is Key n NYCT mandates L ON W ORKS and L ON M ARK n IEEE RTVIS established overall standards n L ON M ARK Association will help complete the details to ensure Interoperability n You’re all welcome to join in
