US: CTI NTCIP Signal Priority - Wireless SNMPv3/TLS

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: CTI NTCIP Signal Priority with those for I-M: Wireless SNMPv3/TLS. The US: CTI NTCIP Signal Priority standards include upper-layer standards required to implement field-to-field traffic signal control priority communications (e.g., for buses and emergency vehicles). The I-M: Wireless SNMPv3/TLS standards include lower-layer standards that support secure infrastructure-to-mobile communications using simple network management protocol (SNMPv3).

Solution Issues Severity: 4

The severity issue score calculation only includes issues associated with standards that are included by default.

Solution Issues:

DefaultSeverityNameTypeDescription
FalseLowOverlap of standards (Minor)OverlapMultiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow. However, as this information transfer is infrastructure-based, agencies can deploy a solution throughout their jurisdiction with minimal downside and can use gateways to connect to other technologies.
FalseLowTime synchronizationPerformance / Applicability GapThe standard requires a highly accurate time shared between participants.
FalseMediumOverlap of standardsOverlapMultiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
FalseHighRegulatory IssueStandardization GapDeployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term.
TrueLowUse TLS for SNMP OptionSecurity GapThe standard allows for multiple security mechanisms. The only defined mechanism that meets the requirements for C-ITS is the one based on TLS.
TrueMediumOut of date (medium)Standardization GapThe standard includes normative references to other standards that have been subject to significant changes that can impact interoperability or security of systems and the industry has not specified if and how these updates should be implemented for deployments of this standard.
