Attributes of line block versions

Note: During line blocking calculation for this line block version, these settings are accounted for in addition to the line blocking procedure parameter settings.

Element	Description
Block version	Number of the block version. The next free number is allocated automatically.
Code	Code of the block version
Name	Name of the block version
Line blocking time interval	In the selection list, you may select the time span for which line blocking is to be calculated. Line blocking regards all vehicle journey sections whose vehicle journey has at least one valid day within the line blocking time interval. Notes The default entry depends on the currently set calendar period. If the annual calendar has been selected, you can select the time span between the two dates (both dates included) forming the line blocking time interval. If the weekly calendar has been selected, you can select the time span between the two weekdays (both days included) forming the line blocking time interval. If no calendar is used, line blocking is performed for 24 hours.

Block version:Interlining tab

Element	Description
Interlining permissible	If this option has been selected, also empty trips for vehicle combination transport between two vehicle journeys can occur in the line block. If this option is not selected, interlining is subject to a layover at the depot (Fundamentals: Introduction to the line blocking procedure). Tip For interlining trips between stop points, you can create interlining matrices (Creating a cost model).
System routes	Note This option is only relevant if option Interlining permissible has been selected. Do not use Routes traversing links and turns which are already open for the particular transport system are determined for interlining. Use If this option has been selected, existing system routes are used for the generation of empty trips. Use exclusively If this option has been selected, existing system routes are used exclusively for the generation of empty trips. Create if required If this option has been selected, existing system routes are used for the generation of empty trips. A shortest path search will be calculated if there is no matching system route. After successful shortest path calculation, a system route will be created from the calculated data. Note The name of this system route is derived from attributes of the block version. To choose them, go to Naming for generated system routes. Use only active system routes If the option has been selected, only active system routes will be used when using system routes for the generation of empty trips. If the option has not been selected, active and passive system routes are used. Note This option is only relevant if one of these three options has been selected: Use system routes or Use system routes exclusively or Create if required.
Distance criterion (link attribute)	In the drop-down list, you can select the link attribute which is to be regarded as best path search criterion, when interlining routes are calculated for empty trips between the last end stop point and the next start stop point. Select one of the following attributes: Length, t-PuTSys, AddValue1, AddValue2, AddValue3 and AddVal_TSys. Note This option is only relevant if option Interlining permissible has been selected.
Naming of generated system routes	The following components of names of the system routes to be generated can be selected and edited: Prefix Enter an arbitrary text Transport system Select a transport system attribute Start stop point Select a stop point attribute End stop point Select a stop point attribute Notes The following naming rules are effective if there is no system route within the network yet with an identical transport system and course: A generated system route could, for example, result in the following name if all four elements are selected: Sys_T_20_40. In order to avoid that identical names are assigned to different system routes that are generated at the same time, a number is appended to the end of the name in case a combination already exists. The numbering begins with 1, for example Sys_B_20_40_1. Existing system routes can be overwritten or updated when given a new name: A system route with an identical transport system and course will be overwritten if its name is identical to the components listed above. If the system route data of a network is supposed to be updated only, the same parameters as for the existing system routes thus need to be entered in the window. If you want to prevent that existing system routes are overwritten, you need to specify a new combination of name components. No existing system routes will then be found in the network. All objects are then created anew, in addition to the existing system routes.

Block version: Layover times tab

Element	Description
Consider pre/post-preparation times	If this option has been selected, the pre- and post-preparation times by vehicle journey section are regarded for line blocking. Tip If for vehicle journey sections, you want to take user-defined time span values into account, instead of pre- and post-preparation times, also select Short turn permitted (Managing vehicle journeys and vehicle journey sections).
Always permit the transition between the sections of a vehicle journey	If this option has been checked, the transition between the sections of a vehicle journey is always permitted. Neither pre nor post preparation times are regarded in this case. Notes This option is only relevant if option Consider pre/post-preparation times has been selected.
Short turn permitted	If this option has been selected, short turn are also permitted for line blocking. In this case, the layover time may differ from the vehicle journey sections pre- and post-preparation times. Notes This option is only relevant if option Consider pre/post-preparation times has been selected. The short turn data is stored as values of the attributes that have been selected for the maximum dwell time and the reduced pre and post preparation times. If the selected attributes are not of the data type duration, values will be read as seconds.
Reduced pre-preparation time	Via the button you can select the numerical vehicle journey section attribute that stores the reduced preparation time to be regarded for line blocking.
Reduced post-preparation time	Via the button you can select the numerical vehicle journey section attribute that stores the reduced postpreparation time to be regarded for line blocking.
Maximum dwell time	Via the button you can select the numerical stop point attribute that stores the maximum dwell time between arrival and departure of two consecutive vehicle journeys to be regarded for line blocking.

Block version: Recurring activities tab

Mandatory user-defined block item types (recurring activities) are automatically scheduled by line blocking and checked in the block check. On this tab, you assign the mandatory user-defined block item types to the vehicle combinations.

Element	Description
VehComb number	Display of the number of the vehicle combinations of the block version
VehComb code	Display of the vehicle combination code of the block version
VehComb name	Display of the name of the vehicle combinations of the block version
Mandatory block item types	Use the button to select the recurring activities that are to be scheduled and checked in line blocking for the block version. Display of the numbers of the line block types
Names of the mandatory block item types	Display of the names of the selected recurring activities

Note: If you have created user-defined attributes for block versions, these are shown in the User-defined attr. tab (User Manual: Managing user-defined attributes).
