At stop points you can specify for each vehicle combination, whether the stop point should be used as a depot by the vehicle combination. A capacity and a minimum downtime time can be specified for each vehicle combination. The capacity is restricted to the number of vehicle combinations, which are allowed to stop at the same time at the stop point (as a depot), as long as the capacity > 0; for capacity = 0 the depot capacity is unlimited. Depots are therefore stop points with downtime function. The downtime in the depot is evaluated with a cost rate that is different (usually lower) from the cost rate for the downtime at a stop point, though both downtimes belong to the block item type layover. A difference is made between the same stop point in its role as a depot and as a stop point.
Stop points serve as locations for different activities in the context of line blocking: As a position for turning, as a location for a user-defined activity (e.g. charging), or as a depot for layovers. Due to infrastructural conditions, the capacity of such locations for vehicle combinations is usually limited.
You can set the total capacity at stop points. It limits the number of vehicle combinations that may be at this stop point at the same time. For the depot capacity, you also specify whether it is a depot (capacity > 0) and how many vehicle combinations can be there. The capacity for activities specifies how many vehicles can carry out an activity there at the same time.
Depot or activity capacities with the value '0' indicate that the activity cannot be carried out at these stop points or that it is not a depot. '0' is therefore also the default value for these attributes at stop points. If the capacity is to be assumed to be unlimited for planning tasks, enter a blank value for the attributes. The total capacity of a stop point must always be greater than or equal to the maximum of the other two capacities. Violations of the rule are displayed in the window. If you attempt to calculate line blocking with non-compliant data, the calculation is aborted with an error message. The total capacity of a stop point is unlimited by default. Unused capacity at the stop point can always be used as block item type ‘Layover’ during line blocking.
Depots are therefore stop points with a downtime function. The downtime in the depot is evaluated with a cost rate that is different (usually lower) from the cost rate for the downtime at a stop point, though both downtimes belong to the block item type layover. A difference is made between the same stop point in its role as a depot and as a stop point.

Attribute |
Description |
|
Is depot |
Specifies that the stop point is a depot. A stop point is a depot if either at least one vehicle combination is permissible or the entry Default values is permissible. |
|
Is depot for standard vehicle combination |
Specifies whether the entry Default values (No combination = Not vehicle combination specific) is permissible. |
|
Minimum depot layover time |
Minimum downtime per vehicle combination in the depot. |
|
Minimum depot layover time for standard vehicle combination |
Minimum downtime in the depot for default vehicle combination (entry Default values). |
|
Depot capacity |
Capacity per permissible vehicle combination. This is the number of vehicles per combination, which is allowed to simultaneously be at the depot. For the value = 0 the capacity is not limited for the respective vehicle combination. |
|
Depot capacity for standard vehicle combination |
Capacity for the vehicle combination no combination (entry Default values). For the value = 0 the capacity is not limited for the standard vehicle combination. |
|
Activity is allowed for vehicle combination set |
Vehicle combination set for which the stop point allows a recurring activity |
|
Activity capacity |
Stop point capacity per activity. The maximum number of simultaneous executions of an activity, indicated by instances of the vehicle combination is indicated. The capacity of 0 for a permitted vehicle combination equals unrestricted capacity. |
|
Attribute |
Description |
|
Total capacity |
Capacity for each permitted vehicle combination. This is the number of vehicles per combination, which is allowed to simultaneously be at the stop point. In case of an empty value, the capacity is not limited for the respective vehicle combination. |
|
Depot capacity |
Capacity for each permitted vehicle combination. This is the number of vehicles per combination, which is allowed to simultaneously be at the depot. For the value = 0 the capacity is not limited for the respective vehicle combination. |
|
Depot capacity for standard vehicle combination |
Same as for depot capacity. This entry is used if no vehicle combinations have been assigned to the vehicle journeys. |
|
Is depot |
Specifies that the stop point is a depot. A stop point is a depot if at least the capacity of one vehicle combination is greater than 0 or an empty value. |
|
Is depot for standard vehicle combination |
Specifies that the stop point is a depot. A stop point is a depot if at least the capacity of the standard vehicle combination is greater than 0 or an empty value. |
|
Minimum depot layover time |
Minimum downtime per vehicle combination in the depot. |
|
Minimum depot layover time for standard vehicle combination |
Minimum downtime in the depot for default vehicle combination (entry Default values). |
|
Activity capacity |
Stop point capacity per activity. The maximum number of simultaneous executions of an activity, indicated by instances of the vehicle combination is indicated. The capacity of 0 for a permitted vehicle combination equals unrestricted capacity. |
|
Activity is allowed for vehicle combination set |
Vehicle combination set for which the stop point allows a recurring activity |
|
Cost rate depot hour |
Cost rate for downtimes at depots |
|
Cost rate layover hour |
Cost rate for downtimes at stop points, not at depots |
|
Cost rate layover hour |
Cost rate for downtimes at stop points, not at depots |
|
Cost rate layover hour units |
Sum of cost rates of the vehicle units for downtimes at stop points |
|
Cost rate layover hour total |
Total cost rate for downtimes at stop points (= cost rate per layover hour + cost rate per layover hour from vehicle units) |
|
Cost rate depot hour |
Cost rate for stay at depots |
|
Cost rate depot hour units |
Sum of cost rates of the vehicle units for downtimes at depots |
|
Cost rate depot hour total |
Total cost rate for downtimes at depots (= cost rate per depot hour + cost rate per depot hour from vehicle units) |
