Offset Reference Point may be specified in the Defaults page of the Preferences dialog see page 128 but setting it as a diagram arterial parameter overrides the default In addition any intersection can override the diagram arterial parameter Changing the Offset Reference Point causes TS PP Draft to change that of every intersection in the diagram Changing the Offset Reference Point does not affect the value of any of the intersection signal offsets however it does affect the point to which the signal offsets refer Thus changing the Offset Reference Point does shift the signals in time resulting in an effective change in offsets but the values of the offsets themselves are unchanged The Offset Reference Point does not affect the reference point of the offsets of the green band bands on Time Space diagrams These always refer to the point at which the green bands begin which will be near the front of the platoon if a queue has built up However since changing the Offset Reference Point does effectively shift the intersection signals in time this change will cause TS PP Draft to reset the offsets of all of the green bands both arterial and new to their default values Vehicle Length This is used on Platoon Progression diagrams only It is the average length occupied by a vehicle stopped along the artery and it is measured in units set in the Units of Measure ment page of the Preferences dialog box feet yards meters etc describ
