Abstract
A temporary or portable traffic signal can be utilized to regulate traffic during power outages. However, when power is restored and the normal operation of the permanently installed traffic signal resumes, then a method of interconnecting the permanent and temporary systems ensures that the operation of the two system are synchronized in predetermined and/or selectable modes of operation. Whenever power is available, an interface detects operation of the permanently installed main system and produces signals that can be used in one mode of operation to direct the portable system to ignore its internal timing sequences and synchronize with the main system, or in another mode of operation to cease its operation.
