Calculating dwell time with PTV Viswalk

PT stop active

 If the option is selected, the public transport stop for the current PT line or PT partial route is activated.

 If the option is not selected, the public transport stop is not operated and is shown in green.

Skipping possible

 If the option is selected, the public transport stop is not operated if the vehicle passes the 50 m mark before the public transport stop and no passengers would like to board or alight.

A public transport stop bay can only be fully skipped if both of these are directly connected to the link, from which the PT vehicle is coming. If the network structure is more complex or if the PT vehicle has already reached the public transport stop bay or the connector, when the 50 m mark is passed, the bay is passed without making a stop.

Skipped public transport stops are reported in the Vehicle Records file with its identifier and recorded as having a public transport stop dwell time of 0 seconds.

Departure offset

Departure time defined according to timetable (Editing a PT line stop)

Dwell time section:All dwell time settings apply for the line stop of a PT partial route.

Minimum

 If this option is selected, a time distribution must be selected to be used as the basis for calculating the minimum dwell time.

 If the option is not selected, the minimum dwell time = 0 seconds.

PT vehicles depart once the minimum dwell time runs out. PT vehicles also depart if the minimum dwell time = 0 seconds when all alighting passengers have alighted.

In addition, you can select the option Late boarding possible for each line stop.

Calculation

Calculation: Alighting percentage as percentage indication when the public transport stop is allocated a pedestrian area as Platform edge or Waiting area. Viswalk pedestrians who board or alight at a public transport stop are modeled. The calculated public transport stop dwell time depends on the time necessary for boarding/alighting passengers. The option Late boarding possible is taken into consideration for the calculation of the public transport stop dwell time.

Alighting percentage

Percentage of the passengers, which will alight at this public transport stop. This value serves the volume-dependent calculation of the stop time.

Boarding and alighting of passengers section

Alighting composition

Composition of the PT-passengers (Defining pedestrian compositions). Within the PT vehicle, the Pedestrian types, corresponding to the selected composition, are generated and the given percentage set is used.

Alighting location

Alighting possible, Boarding possible

Allow or disallow boarding and/or alighting on the right and left. The arrow in the schematic drawing of the public transport vehicle shows the direction of travel.

Late boarding possible

 If this option is selected:

• the minimum dwell time is kept
• the vehicle only departs after all passengers have boarded or vehicle capacity has been reached (Attributes of vehicle types)
• The doors close after three seconds have passed in which no passengers have wanted to board/alight.

 If the option is not selected, the minimum dwell time = maximum dwell time.

• If the Slack time fraction = 0, the PT vehicle departs immediately after the minimum dwell time has been reached.
• If the Slack time fraction > 0, the corresponding share of the remaining time to the departure according to the time table adds to the dwell time if the departure time has not yet been reached.

To ensure that the PT vehicle departs exactly at the time calculated, in case the option is not selected, no passengers can board the PT vehicle as soon as the doors begin to close.

The closing of the doors always begins 3 seconds before departure. The doors also close when a passenger boards immediately before the doors begin to close.
