Vehicle-to-Field

Vehicle-to-Field Communication is the communication between a vehicle, whether it is a personal vehicle or a transit bus, and a field device such as a signal system or traffic monitoring station. In the Bay Area, there are two main types of  Vehicle-to-Field deployments. Both are in their infancy as far as ITS standards application and deployment. The first, Connected Vehicles, is an emerging use of personal vehicles or vehicle probes to communicate with roadside field devices to warn drivers of possible hazards or to communicate traffic conditions. The second, Location Referencing Message Specification (LRMS) communicates the location of a vehicle in a standardized message to a center or to the field. One common application for LRMS is in transit Automatic Vehicle Location (AVL) projects.
