Data model for signal cycle and split optimization

The following attributes of network objects are relevant for the signal cycle and split optimization:

Network object type	Attribute	Description
Signal controllers and subordinated objects	All attributes describing the signal times	Signal times and stage distribution in the initial state
Signal controller	Reference to signal coordination groups	At cycle time optimization with procedure parameter UseCycleTimeFamily=True, only one member of the cycle time family of the coordination group is selected as a new cycle time.
Signal coordination group	Cycle time family
Signal controller	ICA maximum cycle time for optimization ICA minimum cycle time for optimization	At cycle time optimization with procedure parameter UseCycleTimeFamily = false, the new cycle time is selected from the interval between these two attributes.
Signal controller	Optimization method	0 = no signal time optimization for the signal controller at this node 1 = only split optimization 2 = signal cycle and split optimization
Signal controller	Turned off	If the signal controller has been turned off, no signal time optimization will be calculated for the node (main node).
Turn	The attribute for the design hourly volume set in the procedure parameters	Turn volumes
Node model and subordinate objects	All geometry attributes	Lane allocation at node

Optimization is controlled by the following procedure parameters (components of the procedure parameters for intersection capacity analysis):

Procedure parameter	Data type (Standard)	Description
Automatic green time optimization	Bool (False)	Are the signal times always optimized within the ICA calculation? If yes, it depends on the signal controller attribute Optimization method which optimization method is applied to which signal controller.
UseCycleTimeFamily	Bool (True)	At cycle time optimization with procedure parameters UseCycleTimeFamily=True, only one member of the cycle time family of the coordination group (if available) is selected as a new cycle time.
Precision of computation	Full seconds or tenths of seconds	Use this parameter to specify whether full seconds or tenths of a second are permitted as green time start and end.
