1. A system for selectively restricting traffic through at least one phase of a signalized junction, the system comprising a traffic management system (TMS) having a traffic signal controller (TSC),
wherein the TSC is configured to communicate with the TMS and respond to inputs from the TMS, including commands resulting from a traffic detection data input having information about at least one of a traffic count and a traffic user identifier for the at least one phase that is restricted, the at least one phase of the signalized junction that is restricted remaining in a red signal status until the traffic detection data input received by the TMS is determined to be for at least one of the traffic count, the traffic count resulting in a traffic count per time period below a predetermined threshold, and the traffic user identifier matches with at least one of a database record of authorized users and a database record of valid authorization codes to pass through the at least one phase of the signalized junction that is restricted; and
the TMS then sends an input signal to the TSC to provide a green signal status for the at least one phase that is restricted, and the TSC reverts to the red signal status in the at least one phase after at least one of the current signal phase and the current signal cycle while the system is operating in a restrictive mode.
