A traffic management system is disclosed that tells motorist how fast to go in order to make it through a traffic signal while it is in green phase. A Fast Lane On Warning (FLOW) sequencer is in synchronization with traffic phases sequencer (sequencing Red, Green, Yellow, Left Turn and the like) with both sequencers having service cycle period ‘Pi’ . The start times of both sequences are appropriately offset from one another. Sensors up road from the signal provide data on approaching vehicles number per time to a processor that synthesizes the data for one or more “fast” lanes in one or more directions. Using that data, the processor influences the signal and FLOW sequencers as well as emplaced and/or mobile on-board readouts to optimize phase openings and traffic distribution and traffic activity including: (1) To move denser traffic to leaner parts of a pattern; (2) To change net green ‘Tng’ in multi directions contracting the Tng in lean patterns and equally expanding Tng in dense patterns in opposing directions; (3) To change Pi and thus expand or contract all phases concurrently; (4) To encourage increased following distances of close follower vehicles through means of speed readouts. Thus, with optimization of FLOW patterns as they are being consolidated, there can be increased following distances, more uniform distribution, adding more places, resulting in increased safety and even more mobility than that provided by autonomous self-scheduling FLOW outputs alone.
