Project Goals and Objectives

Improve modeling process to address policy and investment questions

Facilitate further development, deployment, and application of procedures

Make operational an advanced travel demand model integrated with a fine-grained, time-dependent network

5

Secondary Objectives

Produce a portable, transferable product

Incorporate products from related SHRP projects

Incorporate travel time reliability into the modeling capabilities

Demonstrate the application of outputs of the integrated model to estimate greenhouse gas emissions using MOVES

Demonstrate the dynamic integrated model set in a real-world environment on selected policies
