Interface: ODOT Traffic Signals and Field Devices - Oregon State Police Vehicles
Architecture Flow Definitions
local signal preemption request (Existing/Planned) Applicable ITS Standards
Direct control signal or message to a signalized intersection that results in preemption of the current control plan and grants right-of-way to the requesting vehicle.
traffic probe data (Planned) Applicable ITS Standards
Vehicle data that is used to determine traffic conditions. In a basic implementation, the data could be limited to time stamped unique identifiers that can be used to measure a vehicle’s progress through the network. In more advanced implementations, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.
