Connected Intersections Implementation GuideDocument #
CTI 4501Description
This Connected Intersection (CI) Implementation Guide defines the key capabilities and interfaces a connected signalized intersection must support to ensure interoperability with production vehicles for state and local IOOs. A connected intersection is defined as an infrastructure system that broadcasts SPaT, MAP, and position correction data to vehicles.Standard In Solutions
