A process that compares the utility of two travel mode choices and determines the probability of using each mode.

An equation used to determine the speed on a network link based on the ratio of the volume to the capacity.

A point that is linked to a TAZ that loads traffic onto the network

The link that connects a centroid to the rest of the network.

An assignment method that iteratively assigns and reassigns traffic based on revised travel times on each link.

Factors that are used in distribution to refine the distance measure between zones.

A process of modeling that began in the 1950s that performs four major steps: trip generation, trip distribution, mode choice, and assignment.

An iterative gravity model used to determine trip interchanges where total productions and attractions are known, but not necessarily balanced.

A process to determine the likelihood of traveling from one zone to another based on the attractiveness of the destination compared to the distance from the origin to the destination.
