This is the 5th step in defining a NEMA control using the VS
NEMA Wizard.
It is
used for defining all timing and phase parameters. It consists of two sub-pages:
Timing
Use
the timing sub-panel for basic parameters about a full cycle:
-
Cycle Time
-
Offset according to a central clock
-
Phase green for each standard NEMA phase from 1 to 8
-
Clearance time between each pair of phases.
All
values are in seconds.
Permissive periods: timing window
Phase
Parameter
The
phase parameters define the timing details for each phase, including overlaps:
Permissive periods: phase parameter as list view
- Standard Phases:
the standard NEMA phases 1 to 8 as shown on the timing panel, using the IVT
parameters
- Pedestrians:
the maximum four pedestrian overlaps, using the pedestrian parameters
- Right Turns:
the maximum four right turn overlaps, using the IVT parameters as well
