Triple
Traffic Management Center to ITS Roadway Equipment: signal control commands
Flow Description
Control of traffic signal controllers or field masters including clock synchronization.
Solution Description
This solution is used within the U.S.. It combines standards associated with US: NTCIP Signal System Masters with those for I-F: SNMPv1/TLS. The US: NTCIP Signal System Masters standards include upper-layer standards required to implement centre-to-field signal-system master communications. The I-F: SNMPv1/TLS standards include lower-layer standards that define one way to retrofit basic security into SNMPv1 implementations (mainly in the US); however, this only secures the communications link and does not provide end-application security and is not recommended for new deployments.
