Transport supply indicators are always calculated for the network objects of the line and stop hierarchy. Additionally, you can calculate them for territories (Fundamentals: Measurement of the transport supply).
As line costing is based on vehicle journeys, empty times and empty kilometers of a line block have to be allocated to the vehicle journeys served by the block. Based on this, costs can be calculated by the PuT operating indicators procedure. Therefore, a line blocking result is required.

Description |
|
For both, the line and stop hierarchy, indicators are always calculated. |
Calculate also for territories If this option has been selected, the indicators are additionally calculated by territory. Also calculate indicators for turns and main turns If this option is selected, the indicators are also calculated by turns and main turns. Also calculate indicators of the 'Territory indicators' procedure If this option is selected, the indicators of the Territory indicators procedure are also calculated (Calculating basic territory indicators). |

Assign empty time and empty km from blocks to vehicle journeys |
No empty time / no empty km If this option has been selected, the properties of empty trips are ignored Empty time from pre- and post-preparation time of vehicle journey / no empty km If this option has been selected, the empty time is calculated as it used to be calculated in previous Visum versions. Empty time(vehicle journey) = pre preparation time + post preparation time Empty km(vehicle journey) = 0 From empty time/empty km of the line block weighted by vehicle journeys If this option has been selected, the empty times and empty kilometers of a line block are uniformly distributed to the vehicle journeys. Empty time(vehicle journey) = empty time(block) / num vehicle journeys(block) Empty km(vehicle journey) = empty km (block) / num vehicle journeys (block) From empty time/empty km of line block weighted by service time If this option has been selected, the empty times and empty km/mi of the line block are distributed to the vehicle journeys according to the service time. Empty time(vehicle journey) = empty time (block) • service time (vehicle journey)/service time (block) Empty km(vehicle journey) = empty km(block) • service km(vehicle journey)/service km(block) From empty time/empty km before + after vehicle journey Considering a user-defined share, the empty time of a vehicle journey results from the total empty time before and after the vehicle journey. The pull-out time is added to the first and the pull-in time is added to the last vehicle journey. Empty time(vehicle journey)= share • empty time before vehicle journey + (1 - share) • empty time after vehicle journey Empty km(vehicle journey)= share • empty km before vehicle journey + (1 - share) • empty km after vehicle journey |

Times from passenger trip chains |
For the calculation of the analysis horizon: Times from passenger trip chains are often included when calculating indicators You can specify how extrapolation is performed for the analysis horizon. An overview of the respective indicators is provided in the IndicatorSource.xls file, in the ...Program Files\PTV Vision\PTV Visum 2025\Doc\Eng.
If this option is selected, you can set the following factors for calculation: Factor for projection of the supply Input of a factor for the projection of the transport supply; data type: floating-point number Factor for extrapolation of time-dependent costs Input of a factor for the projection of the time costs; data type: floating-point number
If this option is selected, the extrapolation factors calculated by Visum for passenger trip chain times are used: Factor supply for passenger trip chain times = Factor supply for valid days (daily) / Number of days of AP Factor hourly costs for passenger trip chain times = Factor hourly costs for valid days (daily) / Number of days of AP Define the Transport supply and the Cost per hour for each PuT valid day (Creating a valid day). |
