Vehicle-to-Infrastructure

The phrase unstructured data usually refers to information that doesn't reside in a traditional row-column database Information that either does not have a pre-defined data model or is not organized in a pre-defined manner (e.g., pictures or video).

Vehicle-to-Infrastructure (V2I) Communications for Safety is the wireless exchange of critical safety and operational data between vehicles and roadway infrastructure, intended primarily to avoid motor vehicle crashes. The vision for V2I research is to enable safety applications designed to avoid or mitigate vehicle crashes, particularly for crash scenarios not addressed by V2V communications alone. Another important objective of the V2I research is national interoperability to support infrastructure and vehicle deployments.
