Scope
This Technical Specification defines the physical means and protocols to be used to communicate with dynamic message signs (DMS) and road weather information systems (RWIS). Where necessary, the functionality required to implement the protocol is described.
NOTES:
1 For the purpose of this Technical Specification DMS consist of variable message signs (VMS), changeable message signs (CMS), electronic speed limit signs (ESLS), lane use signs (LUS) and school zone alert signs (SZAS).
2 This communication protocol also supports the display of travel times on VMS.
