1. A portable traffic management system for use at a worksite, the portable traffic management system comprising a control module and a plurality of traffic control systems, the control module configured to:
receive data from at least one wireless control device in accordance with a first communication standard;
using the data received from the at least one wireless control device, generate control signals for coordinated control of the plurality of traffic control systems; and
in accordance with at least a second communication standard, transmit the signals for coordinated control of the plurality of traffic control systems to at least a first of the plurality of traffic control systems,
wherein the first of the plurality of traffic control systems is a master traffic control system, configured for coordinated control of at least one slave traffic control system in accordance with the control signals generated by the control module, and
wherein the control module is configured to operate in either of an automatic mode and a manual mode, wherein:
in the manual mode the control signals are generated by the control module in accordance with the data received by the control module from the at least one wireless control device; and
