If NO, add the demand phases in this stage (or the stage itself if stage is

demanded) to “Phases & stages to Get right of way”. Then try next stage in

cyclic order (starting at Step 1).

5. Will more demanded phases be serviced by this stage than in previously

“Suggested Stage”?

If YES, set “Suggested Stage” equal to this stage.

If NO, add the demanded phases in this stage (or the stage itself if stage is

demanded) to “Phases & Stages to Get right of way”. Then try next stage in

cyclic order (starting at Step 1).

At the end of the decision-making process the “Suggested Stage” will either be

a new stage other than the current stage, or it will have remained as the current

stage.

If the suggested stage is other than the current stage, the controller then checks

the “Stage movement restriction” table appropriate to the mode, to see if it can

make the move, see below:

If the move from the current stage to the “Suggested Stage” is prohibited, the

controller will stay in the current stage until the decision-making process comes

up with a different “Suggested Stage” to move to.

If the move from the current stage to “Suggested Stage” is an Ignore move, the

controller will immediately return to the decision-making process, it will

remove from the equation the demanded phases which would have been served

by the previously “Suggested Stage” (so that process does not come up with

same “Suggested Stage” again), and then it will start again searching for a

stage to move to.

If the move from the current stage to the “Suggested Stage” has an alternative

stage move specified, the controller will move to the alternative stage and then

restart the decision-making process.

If the move from the current stage to the “Suggested Stage” is unrestricted, the

controller will move to the “Suggested Stage” and then restart the decision-

making process.

2.5.1 Effects of Modes other than V.A. on Stage Change Algorithm

In V.A. mode, the stage change algorithm is allowed to suggest a stage based on the

influences current at the time without any manipulating of those influences.
