Adding platform edges
|
|
Notes:
- You require the add-on module Viswalk for microscopic pedestrian simulation.
- Platform edges are not automatically moved along with the link or the public transport stop nor are they adjusted to changes in length. Therefore, only add the platform edges once the links and PT stops will no longer be changed. This way you ensure that a transition between the network and the PuT vehicle remains possible for pedestrians.
|
You can define areas of the type Polygon and Rectangle as a Platform edge.
For a stop, you can add an area of the type Rectangle as platform edge to the left or right of the link on which the stop is located. This platform edge follows the user-defined link using inserted points, if, for example, the link is not straight. Platform edges are created with a width of 2 m immediately next to the link.
If boarding passengers are to board and/or alight from both sides, add platform edges to the left and the right.

Notes:
- When generating platform edges, the volume [Pers./h] is changed in the attribute Boarding passengers in a relative volume and existing values are taken over. Every public transport stop with an area for Public transport usage is used by the passengers, who are generated as pedestrians. These passengers are proportionately distributed among the PT lines.
- If there are no pedestrian areas with the attribute Public transport usage, the passenger volume is distributed over the PT stops exactly according to the absolute values.
|
- The Public transport usage attribute can be used to define a pedestrian area as a Platform edge or a Waiting area for one or more selected stops (Modeling construction elements). Based on its type, you determine the shape of the platform edge using the shape of a polygon or the rectangle of the pedestrian area.
- A pedestrian area with the attribute Public transport usage defined as a Platform edge must fulfill the following conditions:
- The platform edge and the lane with the public transport stop must be directly adjacent or overlap so that alighting passengers may alight on the platform edge and boarding passengers may board the PT vehicle from the platform edge. The overlapping must be smaller than half of the width of the pedestrian area. This means that the center line of the platform edge, which is parallel to the lane and thus to the public transport stop, must lie outside the lane.
- The length of the pedestrian area parallel to the lane must be at least the length of the public transport stop, so that when the public transport vehicle stops, no vehicle door lies outside of the platform edge.
- If you have not defined the area of the platform edge via the shortcut menu commands Add platform edge left or Add platform edge right or have decided to edit it later on in the network editor, make sure that the distance between the lane on which the public transport vehicle stops and the platform edge are is 2 m maximum. Otherwise, the PT vehicle will not open its doors.

Note: When two platform edges with different parameters overlap, a warning is displayed during the check. Even so, Vissim assigns the platform edges to the right doors and the simulation is not interrupted.

1. On the Network objects toolbar, click Public transport stops.
2. In the Network editor, right-click the desired PT stop.
3. From the shortcut menu, choose Add platform edge left or Add platform edge right.
The platform edge is displayed in the Network editor next to the link. Default color: pink. All relevant area attributes are set automatically, e.g. for public transport usage Platform edge and for public transport stop(s), the number of the PT stop selected. The name of the pedestrian area includes numbers and sides of the PT stop, e.g. platform edge PT stop 1 (right). The name is not automatically adjusted when the area of the platform edge is allocated a later point in time of another public transport stop.
