Attributes of signal heads

The Signal Heads window opens when you insert a network object and have selected to have the Edit dialog automatically opened after object creation (Right-click behavior and action after creating an object). By default, only the Signal Heads list is opened.

Into the window, you enter attribute values for the network object. For network objects which have already been defined, you can call the window using the following functions:

► In the list of network objects of the network object type, double-click the row with the desired network object.
► In the Network editor, select the network object of your choice. Then, on its shortcut menu, click Edit.

The network object may have additional attributes. In the network objects list of the network object type, you can show all attributes and attribute values. You can open the list via the following functions:

► On the network object sidebar, right-click the desired network object type. Then on the shortcut menu, click Show List (Shortcut menu in the network object sidebar).
► In the Network editor, select the network object of your choice. Then, on its shortcut menu, click Show In List (Selecting network objects in the Network editor and showing them in a list).
► On the Lists menu, in the desired category, click the network object type.

In the network objects list of the network object type, you can edit attributes and attribute values of a network object (Selecting cells in lists), (Using lists).

The objects of this object type may have relations to other objects. This is why the attributes list is shown as part of a coupled list (on the left). On the Lists toolbar, in the Relations box, you can show and edit the coupled list with the attributes of the desired relation on the right (see below Showing and editing dependent objects as relation) and (Using coupled lists).

Note: In lists, you can use the Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list).

1. Make the desired changes:

Element	Description
No.	Unique number
Name	Designation
Link	Link for which the signal head has been defined
Lane	Ln: Number of lane to which you have added the signal head.
At	Position (Pos): Distance from start of the link or connector
SC - signal group	Number and name of respective signal controller SC and respective signal group SG
Type	Display of the signal head in 3D animation during a simulation run or test run: Circular Left arrow Right arrow Invisible: Hides the signal heads (in 2D mode as well). If the normal signal group of an arrow signal head has the signal state Red or Off and an Or signal group is defined for this signal head, the signal state or the Or signal group is shown as a bar without an arrow. This also applies if the normal signal group is yellow and the Or signal group is red-amber or reversed.
Or signal group	OrSG: Is the Or Sig.gr. option: Second signal group which shall influence this signal head. Such a signal head shows exactly in green if at least one or both signal groups are green. If the first signal group shows red, the signal head shows the state of the second signal group also in amber or red-amber. For the display of signal states of both individual signal groups, a short link with a signal head on both signal groups can be created next to the link. SC: Number of signal controller or the Or signal group Signal group: Number of Or signal goup You can use the Or signal group to model vehicles turning right with green right arrows, which are indicated by their own signal group before and afterwards and by a circular symbol during the actual phase as contractually stipulated. Define two signal heads on different links: a signal head for vehicles traveling straight ahead; a signal head for vehicles turning right. This must be located on a connector not used by vehicles traveling straight ahead. In the signal group of the green arrow for vehicles turning right, enter the signal group of the vehicles traveling straight ahead as an Or signal group.
Compliance rate	ComplRate: Every vehicle and every pedestrian has an individual random number. This number is between 0.0 (0%) and 1.0 (100%) and is evenly distributed. If this random number is greater than the compliance rate of a signal head, the vehicle or the pedestrian will ignore the respective signal head. Minimum value: 0.0 = 0% Maximum value: 1.0 (default value) = 100% If the compliance rate is below 100%, use conflict areas to model intersection control (Using conflict areas).
Discharge record active	DischRecAct: If this option is selected, the vehicles of this signal head area are taken into account in the discharge record (Saving discharge record to a file).
Is block signal	Is block signal (IsBlocksig): Selecting this option defines the signal head as a block signal (Modeling railroad block signals). The fields SC, Signal group and Or signal group are deactivated.
Amber speed	Block signal amber speed (vAmberBlock): Speed assigned to a train when it travels past the block signal and the state of the block signal is Amber (Modeling railroad block signals). The Is block signal option must be selected. Default value 0 km/h.
Label	If this option is not selected, the label for the signal head is hidden if the label for all signal heads is selected.
Vehicle classes	VehClasses: Vehicle classes for which the signal head is valid. For example, you can define a separate signal for buses on a link, which should be ignored by private transportation. The option All Vehicle Types is a virtual vehicle class that automatically includes all new vehicle types and vehicle types that have not been assigned a vehicle class yet.
Pedestrian classes	PedClasses: If the signal head is defined on a link for which the attribute Is pedestrian area is selected: For the simulation of pedestrians, the pedestrian classes that are valid for the signal head.
Slow down distance	SlowDownDist: In list only: Distance from stop line at which pedestrians start to reduce their speed in order to stop at the stop line. Default 3 m.
Lane width	LnWid: only in the list: Width of the lane at the position of the marker of the signal head
Rotation angle	RotAngle: only in the list: Horizontal rotation angle of the link segment for which the signal head is defined

Showing and editing dependent objects as relation

The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

1. In the list on the left, click the desired entry.

The list on the right contains attributes and attribute values of network objects, and/or base data allocated to the network object selected in the list on the left (Using coupled lists):

Vehicle classes (Defining the vehicle class)
Pedestrian Classes (Attributes of pedestrian classes)

The attributes are described further above.

2. On the list toolbar, in the Relations list, click the desired entry.

3. Enter the desired data.

The data is allocated.
