Editing a PT line stop

PTLine

Name of PT line that services the PT line stop.

Public transport stop

Number and name of public transport stop of the PT line 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. The color is based on the graphic parameter Inactive stop color.

A public transport stop created in the Vissim network according to the definition of PT lines is not automatically contained in a PT line path, even when placed on a link that is traversed by a PT line. You can enable the Active attribute to include the public transport stop into the PT line path.

If a PT stop is not to be serviced by a PT line, disable its Active attribute.

If the Change of driving direction attribute is selected for an active public transport line stop, the stop is displayed in the color of the Active direction-change-stop color graphic parameter.

SkipPoss

Skipping possible: If the option is selected, the stop is not served:

• if the vehicle passes the 50-meter mark before the stop and no passenger wishes to board or alight
• depends on the method used for calculating public transport dwell time (Defining dwell time according to dwell time distribution), (Calculating dwell time according to the advanced passenger model), (Calculating dwell time with PTV Viswalk)

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.

ChgDrivDir

Change of driving direction: If this option is selected, the public transport vehicle will leave the PT stop with the rear edge first, in the direction it came from. For this purpose, a link must be modeled in the opposite direction to the link from which the public transport vehicle accesses the PT stop. If, for example, the public transport vehicle is to follow a public transport line for a continuous timetable, both links must be connected via a connector. If the public transport vehicle is not to follow a public transport line, the public transport line can end downstream of the PT stop. Then the new link sequence must be assigned to the public transport vehicle via a partial PT routing decision.

If the public transport vehicle leaves the PT stop in the direction it came from, its attribute Direction of travel is still Forward, as the direction of travel corresponds to the overlapping link in the opposite direction. The Turned attribute of the vehicle is selected. Turn signal and 2D/3D model are displayed in reverse direction.

DepOffset

Departure time offset: Scheduled departure time at this stop relative to the departure time defined for the PT line for this journey (= scheduled journey time between the first line stop and this stop). If the PT line's slack time fraction is defined as less than 1, the vehicle can also depart earlier accordingly.

The time offset is used additionally for boarding and alighting time (boarding/alighting). The resulting departure time is calculated as follows:

Simulation second of arrival + dwell time + max (0, ((departure time of PT line + departure offset) - (simulation second of arrival + dwell time)) • slack time fraction of PT line)

If the departure time, according to the time table, is later than the point in time, which is the sum of the arrival time and dwell time, the PT vehicle waits until the departure time, according to the time table if the Slack time fraction equals 1. Value range from 0.00 to 1,00.

If the Slack time fraction of the line is 0.00, the timetable will not be taken into consideration. In this case, the settings in the range dwell time are taken into consideration for the calculation of the Dwell time. The timetable is taken into account, if the time offset attribute of the public transport line is > 1.

For line stops in PT partial routes, the following applies:

• As long as a PT vehicle has not completed its original line route, its Departure offset is treated like an offset at a line stop of the original route.
• Once the PT vehicle has passed the "to section" of its original line route, the Departure offset specified for a PT partial route stop is interpreted as relative to the simulation time when the vehicle passes the respective routing decision point.

PedsAsPass

Pedestrians as passengers: Pedestrians of an area are used as passengers for public transport. The area is a waiting area or a platform edge. The area is assigned at least one PT stop.

DwellTmDef

Dwell time definition depends on the method used for calculating public transport dwell time (Defining dwell time according to dwell time distribution), (Calculating dwell time according to the advanced passenger model), (Calculating dwell time with PTV Viswalk)

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.

• Distribution: Time distribution, on the basis of which the minimum dwell time is determined.
• 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.

All settings for the dwell time apply for the line stops of a PT partial route.

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 location: Distribution of the alighting passengers at the doors of the PT vehicle at this public transport stop (Using location distributions for boarding and alighting passengers in PT). Within the PT vehicle, the alighting passengers at this PT stop are distributed to the vehicle doors based on the selected Alighting composition. If areas without passengers are defined on the 2D/3D model segments of the public transport vehicle, these areas are excluded from the distribution.

Alighting possible left,

Alighting possible right,

Boarding possible, left,

Boarding possible, right

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 depending on the value of the Door closure delay attribute.

 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 doors also close when a passenger boards immediately before the doors begin to close.

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.

Door lock duration before departure

DoorLockDurBefDep: This dwell time of the PTV vehicle is the time until departure of the vehicle after the doors have been fully closed. Default 2.0 s

Door closure delay

DoorClosDel: Time after which the last pedestrian has walked through doors until the doors begin to close. Default value 3.0 s.

If the option Late boarding possible is selected at the line stop, the door closer’s delayed mode will only start, if the boarding delay is no longer effective.(Calculating dwell time with PTV Viswalk).

If the option Late boarding possible is not selected at the line stop, the door closer’s delayed mode will start after the last pedestrian has walked through doors.
