Defining parking routes

If you want a vehicle to use a parking lot, define a vehicle route of the type Parking lot that leads to the desired parking lot (Parking routes). To define a parking route, insert a routing decision on a link and on a destination section located on the parking lot of your choice. For a routing decision, you may also define multiple destination sections located on different parking lots. Your routing decision may lie on a connector. The destination section may also lie on a connector, if the parking lot is located on a connector. The Reverse parking attribute must not be selected for these connectors. When modeling a parking route on links and connectors, avoid self-intersecting.

If the vehicle traverses a routing decision of the type Parking lot, Vissim, checks whether there is a parking rate and a parking duration for the current time interval at the routing decision. If this is the case, Vissim can decide whether the vehicle will park or not.

You can assign the interval limits via the time intervals (Defining time intervals for a network object type), (Calling time intervals from an attributes list). If a distribution on a percentage basis of the traffic volume to the routes of a routing decision varies temporally, you must define multiple time intervals which do not overlap each other.

For parking routing decisions, time intervals assigned in the Select Attributes window, from the list on the left, are taken into account for the subattributes Parking duration and Parking rate. They can be selected and displayed in the Parking Routing Decisions list (Selecting attributes and subattributes for columns of a list).

If you define a parking route to a parking lot in which the vehicle can back out of the parking space, Vissim will create the parking route internally, using several sections: The shortest path search defines the section of the routing decision leading to the parking lot. For driving backwards onto the original route, Vissim defines the following sections:

• A section extends up to the turning point where the vehicle stops reversing, comes to a standstill and then continues its route driving forward.
• A section extends up to the point where a connector begins that leads to the parking lot.
• A section extends from the beginning of this connector up to the next section of the original route.

Notes:   You can specify that you need not press the Ctrl key when adding network objects (Right-click behavior and action after creating an object). For some network objects there are windows in which the attributes of a network object can be defined and edited. There are lists for this, for all network objects. You can choose whether you want to open a window, a list or neither of the two for the definition of network objects in the Network Editor (Right-click behavior and action after creating an object).

1.  On the network object sidebar, click Vehicle Routes.

The button is highlighted. The variant of the network object type is displayed in parentheses and the button is shown.

2.  Click Vehicle Routes again.

A list box opens.

3.  Then select Parking lot.

Tip: Alternatively to the following steps, to insert a routing decision, on the shortcut menu, click Parking routing decision.

4.  Hold down the Ctrl key and in the Network Editor right-click the desired link or connector on the desired position of the routing decision cross section.

5.  Release the keys.

By default, a purple bar is inserted. If for this start section you want to insert multiple destination sections, carry out the following steps accordingly. Thereby you can insert a destination section into a parking lot and subsequently define each of its attributes.

If you would like to insert a destination section for this start section, execute the next steps only once.

6.  Move the cursor into the parking spaces of the desired parking lot.

If Vissim does not find a valid link sequence, neither a blue band nor a turquoise bar are displayed, or the band might be interrupted. Select another parking lot for the destination section or correct the Vissim network, for example if a link is not connected properly to a connector.

If Vissim finds a valid connection via a link sequence, between the start section and the position the mouse pointer is pointing to, the link sequence is displayed as a blue band by default.

On the edge of the link, which you are pointing to with the mouse pointer, a black arrow is shown in the direction of travel. A turquoise bar within the parking lot indicates the possible position of the destination section.

7.   Click this position.

8.  To insert additional destination sections, in respective parking lots, click the desired position.

9.   If you do not want to add an additional destination section, in the Network editor, click in an empty area.

A turquoise bar is added for the destination section by default. For vehicle routes of the type Parking Lot, the route ends at the beginning of the destination parking lot. The Parking routing decisions list opens, if automatic opening of a list after object generation is selected (Right-click behavior and action after creating an object). The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

10.  Edit the attributes (Attributes of parking routing decisions), (Attributes of parking routes).

Tip: You may assign a routing decision to a destination section later on: 1.  On the network object sidebar, click Vehicle Routes > Parking Lot. 2.  Hold down the Ctrl key. 3.  In the Network Editor, right-click the routing decision. 4.  Release the keys. 5.  In the parking lot of your choice, click the desired position of the destination section. 6.   If you do not want to add an additional destination section, in the Network editor, click in an empty area.
