There are several types of signal coordination systems available today. The firm studies each client’s capabilities to operate and maintain a system and identifies compatible systems within the existing staff capabilities to operate and maintain them. Unless required by the client, only proven equipment is specified for use.
Our experience includes over ten closed loop system designs utilizing hardwire interconnect, fiber optic, radio control, microwave and time of day synchronization. The firm has designed systems to replace existing Urban Traffic Control Systems (UTCS) and other types of central control. TQC has specified and worked with NEMA controller systems, 180 controller systems, and is familiar with the new National Transportation Communications for IT Software Protocol (NTCIP).
