The instructor then asks: How would the outputs of conventional four-step travel demand models differ between these two future land use scenarios.

This study aims to examine the limitations in the dominant approaches to understand how they may misguide the planning process for multifamily housing development. Specifically, we aim to examine the vehicle and person trip generation rates associated …
