MODELS CREATED

•Forecasts travel patterns on a daily basis for a specified region.

MACRO

•Forecasts travel patterns on a peak hour basis for a more specialized region.

MICRO

MACRO TRAVEL DEMAND MODEL

•Determines the number of trips produced or attracted to each TAZ

Trip Generation

•Origins and Destinations are paired using a gravity model.

Trip Distribution

•Trips proportioned onto all available modes of transportation.

Mode Choice

•Allocates trips between O/D pairs to particular routes based on travel costs.

Conventional Auto

•Origin / Destination tables for trucks and other large goods vehicles.Trucks

•Origin / Destination tables for NEVs. Considered an alternative mode of transportation expected to account for a large portions of traffic throughout the Project.

Neighborhood Electric Vehicles

•Expected transit vehicles required along a given route in the network.

DESTINY MICRO MODEL

• Construction of the Destiny model is in the very preliminary stages, and is evolving on nearly a daily basis. Future goals include:

• Determining optimum location of signalized intersections. 100+ signals anticipated.

• Investigate all transportation systems that conserve energy, have little environmental impacts, and provide congestion relief for potential implementation into the project.

DESTINY MICRO MODEL

Summary• Paramics is being used as a

planning tool for design of Destiny due in part from the success of the Paramics model for Miami, Florida (140 signalized intersections).
