Links: DUE tab

In this tab, you can specify settings for the procedure Dynamic User Equilibrium (DUE) (Dynamic User Equilibrium (DUE)).

Note: The settings in the DUE tab only apply to the PrT procedure Dynamic User Equilibrium (DUE).

Element

Description

Average space required by car unit per lane

Enter the length required by a car unit in case of a fully congested link, i.e. when the maximum vehicle density has been reached.

Note

The value needs to fulfill the following condition:

SpacePerPCU <= 1000 • v0PrT / (2 • 1.05 • CapPrT/ NumLanes)}

The default value is calculated as follows:

SpacePerPCU = MIN {7.00, 1000 • v0PrT/(2 • 1.05 • CapPrT/ NumLanes)}

vWave

Enter the slope for the hypercritical branch of the fundamental diagram (Fundamentals: Network performance model)

Note

The default value is calculated as follows:

Max{ v0PrT • 0.3, CapPrT/(1000/LinkSpacePerPCU – CapPrT• 2/v0PrT)}

Tip

Use the Multi-edit functionality to allocate a value to all links (Resetting DUE attributes to the default values).

Fundamental diagram type

Use the list box to select one of the two types of the fundamental diagram (Fundamentals: Network performance model).

Out capacity

If the option has been selected, you can enter an out capacity for the link.

If the option has not been selected, the regular capacity PrT (CapPrT) will be used.
