Modeling links for vehicles and pedestrians

You can model links on which vehicles and pedestrians move. This vehicle and pedestrian must be defined as vehicle types.

Within a link section, the number of lanes cannot be changed. If the number of lanes should deviate, you must set a link for every link section. Subsequently, you can split links and change the number of links (Splitting links).

Defining sequence and modeling techniques for links

• Define the links for main roads in one direction.
• Add intermediate points and model the curvature of a link.
• Define the opposite lane. Thereby you can generate the newly created link with a different number of lanes. Allow the links to run corresponding to the line of a road.
• If you add additional links, connect them via connectors.
• Determine the number of legs per intersection and add links. In the intersection area, allow links in the middle of the intersection to begin and end. If the number of lanes changes, pay attention to the correct connection via connectors.
• Define the number of lanes per link on the nodes.
• Define the number of turning lanes in the node.
• Define the possible turns, lane expansions and lane reductions at the connectors.

Deleting a link or lane

When you delete the lane of a link bordering connectors, this lane will also be deleted from the connectors.

Even if for a link the attribute Has overtaking lane is selected, you can delete the link. To delete a lane from such a link, the link must have at least three lanes, including the overtaking lane.
