TMC In-Vehicle Signing Management Functional Area
Description
'TMC In–Vehicle Signing Management' controls and monitors RSEs that support in–vehicle signing. Sign information that may include static regulatory, service, and directional sign information as well as variable information such as traffic and road conditions can be provided to the RSE, which uses short range communications to send the information to in–vehicle equipment. Information that is currently being communicated to passing vehicles and the operational status of the field equipment is monitored by this application. The operational status of the field equipment is reported to operations personnel.
