Abstract
A roadside signal system and a roadside controller are provided relating to the control and operation of roadside signals and signs, such as those used by departments of transportation and municipalities. The roadside signal system and controller are configured to operate using National Transportation Communications for Intelligent Transportation Systems Protocol (“NTCIP”) compliant transmissions at both a local and remote level. The roadside controller by itself and as a part of the roadside signal system operates a local network to control multiple signs or signals from a single connection to a central network, thus saving physical space within the roadside cabinets used to store such controllers and virtual network space on the central network.
