ITS Roadway Equipment to Maint and Constr Management Center: traffic detector data
Flow Description
Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.

Solution Description
This solution is used within the U.S.. It combines standards associated with US: NTCIP Transportation Sensors with those for I-F: SNMPv1/TLS. The US: NTCIP Transportation Sensors standards include upper-layer standards required to implement centre-to-field transportation sensors (e.g., vehicle detectors) communications (e.g., real-time). 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.
