MOVEMENT IS HUMAN

Better data.
Deeper understanding.
Meaningful change.

How we move shapes access to opportunity, exposure to climate risks, and the spread of disease. Understanding those connections is at the heart of our work.

Led by Dr. Chenfeng Xiong, Villanova Human Mobility Labs brings together transportation engineering, data science, and public health. We turn complex mobility patterns into evidence that communities and decision-makers can use.

OUR RESEARCH IN ACTION

Mobility Intelligence for
Transportation, Health
and Climate.

We work with public agencies and research partners to understand travel, improve access, and study the links between mobility, health, and climate.

Transit Equity Credits

Can tradable credits make public transit more equitable? We model dynamic pricing and heterogeneous traveler needs to examine new approaches to transit incentives and financing.
