Highway Assignment in VISUM

Simultaneous loading of multiple modes (SOV, HOV, …):

• All or nothing

• Incremental loading

• Equilibrium (user-optimal)

• Learning method (user-optimal)

• Bi-criterion user optimal equilibrium (“TRIBUT”)

• Stochastic Assignment

• Dynamic-Stochastic Assignment

Assignment can be link based and/or node based

Delay computation at intersection can be:

• Turning movement based (using volume-delay functions)

• Entire intersection based (using volume-delay functions — T-Model™ standard)

• Turning movement based (using HCM or similar methodologies — powered by TRAFFIX™)
