US: NTCIP Signal Priority - SNMPv1
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: NTCIP Signal Priority with those for I-F: SNMPv1. The US: NTCIP Signal Priority standards include upper-layer standards required to implement center-to-field traffic signal control priority communications (e.g., for busses and emergency vehicles). The I-F: SNMPv1 standards include lower-layer standards that define how SNMPv1, which does not provide any security, is used within some deployments within the ITS industry. This solution is no longer recommended due to known security vulnerabilities.Relevant Regions:
