Studies of IVHS electromagnetic compatibility issues

Describes the approach of the Federal Highway Administration (FHWA) to gather information and analyze issues relating to the electromagnetic compatibility (EMC) of intelligent vehicle highway system (IVHS) Efforts to define the expected electromagnetic environment of the roadway, the frequency/spectrum availability based on geographic area, and system coverage for specific and generic cases are described, together with the ongoing examinations of how the electromagnetic environment of the roadway affects IVHS systems and how IVHS systems affect the electromagnetic environment of the roadway.
