Functional Summary
• Modular and scripting-based structure allows the development of any model system
(4-step, discrete choice, activity..)
• Equilibrium feedback on part or all of model chain using fixed number of iterations or
user-controlled criteria
• Automated naming and saving of intermediate results in model equilibrium feedback
iterations
• Module for network merging, comparison, calculation, analysis
• Module for matrix and vector merging, squeezing/expanding, comparison, calculation
and analysis
• Module for supply checking, calculation, pathbuilding, assignment and skimming
• Module for public transit checking, generalized cost calculations, discrete route
identification, alternative selection, skimming, and multi-path assignment
• Module for highway and public transit matrix estimation and updating from existing
matrices, partial matrices, counts..
• All calculations done in floating point, maintaining complete accuracy at all levels
• Combined mode and destination choice models
• Heirarchical (nested), multinomial, binary mode choice models
• Generalized cost mode choice models using aggregate logit techniques
• Unlimited matrix and vector manipulations, merging, computations
• Regression trip generation models
• Destination choice models using discrete choice techniques
• Stochastic traffic assignment
