While it is well known to power traffic control devices (for example, traffic lights) by an alternative energy source during power outages, some embodiments of the present invention additionally have: (i) a set of control computer(s), remote from the various traffic control devices, that is powered by an alternative energy source during a power outage; and/or (ii) a communication network, for communications between the set of control computer(s) and the various traffic control devices, that is powered by an alternative power source during a power outage. The use of alternative power to power the control computer(s) (for example, a hub) and/or the communication network allows the traffic control devices to continue to operate in a coordinated manner as instructed by the control computers, thereby avoiding a situation where the traffic lights begin operating independently of each other during a power outage.
