Imagine you have some new turns to analyse. The first step is to add them either to the existing signal groups or to new groups.
Example: The through turn associated with Signal 1 in the base geometry is not the same through turn as the one in the new geometry, so it will not appear in the new geometry configuration view.
No Signal 2 turns exist in the new geometry, so they will not appear in the new geometry configuration view.
Add the new through turn in Signal 1 and create Signal 3, which only exists in the new geometry.
If the duration of the phases of the new geometry are no different from the base geometry, you can edit the Base Control Plan by selecting the new signal groups in the corresponding phase. Then use the same Base Master Control Plan in the new scenario.
You will only have to create a new Control Plan and Master Control Plan if the duration of the phases for any intersections in the new geometry are different from the base durations. In this case, you must code the new durations in a new Control Plan and then assign it, together with the Base Control Plan, to a new Master Control Plan.
This new Master Control Plan must contain the base control plan in Zone 1 and the new one in Zone 2. Control Plans in Zone 2 will override those in Zone 1, therefore, if an intersection has both of them defined, the one in Zone 2 will be the one applied.
WARNING: Do not use a copy of the base Control Plan in the new Master Control Plan to code the new phase durations because if you want to edit the base control plan afterwards, you will have to apply the changes twice, once in the original base Control Plan and then again in the copy.
