Assignment

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

Highway Assignment in VISUM

4 Stage Models

Transit

Post Assignment Analysis

VISUM stores all paths for every OD pair from assignment

Run select flow analysis without having to rerun assignment

Select flow analyses

• Select links, nodes, zones

• Area flows

• Screen lines

• O/D matrices

Travel time isochrones

Node flows

Integration with Traffic Engineering

Traffic Signal Editor

Store traffic signal data using Simple NEMA editor

Traffic signal data shares same format as VISSIM

Intersection Modeling in VISUM

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™)

Turning Movement Based Impedances (using volume delay functions)

Node Based Impedances (using volume delay functions)

Turning Movement Based Impedances (using HCM methodologies)

Intersection Performance

Evaluate Intersection Performance using HCM Methodologies during or after assignment (powered by TRAFFIX™)
