Developing a model for Transit Oriented Development in Latino Immigrant Communities: A National Study of Equity and TOD

Gerardo Sandoval
Multimodal transportation and land use decisions have important effects on vulnerable low-income communities.

In this era, building new freeways to reduce congestion is less feasible due to the high capital and social costs. Thus, the effective management and operation of existing freeway facilities has become a preferred approach to reduce traffic… Read More
