Everyone deserves the freedom to move.

We power a global network of change leaders advancing transportation that works for all.

Transportation shapes how we live.

It determines how we access work, education, and opportunity.

When people need a car just to participate in daily life, mobility becomes a barrier instead of a bridge.

Transportation can connect us or divide us.
Create opportunity or limit it.


Who gets to move determines who gets to participate.

We bring together research, relationships, and expertise from around the world to help communities create shared transportation systems that are safe, accessible, affordable, and sustainable.

  • We are researchers who generate evidence, translate insights, and equip mobility leaders with the tools they need to implement solutions that improve everyday lives.

  • We are practitioners who help communities navigate complexity, align priorities, and develop solutions that work in their unique context.

  • We are conveners who bring people together to build shared understanding, strengthen partnerships, and move from conversation to collective action.

The work, in their words

“SUMC was a critical partner for us in successfully delivering high-quality technical assistance to communities as part of USDOT’s Thriving Communities Program. We relied heavily on SUMC staff’s flexibility, technical insights, and community engagement capabilities to navigate complex challenges and deliver tangible results.”

Steve Abbott, Principal, RMI

“The New Summit is a perfect example of what investing in people looks like. The summit format involved getting a group of leaders together in a room for a few days and pushing the envelope in discussions about mobility, connectivity, planning and funding. When we take the time out of our busy schedules to sit in a room together and focus, new plans and ideas take shape.”

Natalie Bond, Land Development Manager, Bedrock Detroit (Detroit/Greater Michigan Change Team)

“We’ve worked with SUMC for many years now on a variety of international research projects. I always find they are creative and flexible, but also reliable and executive.”

Henrik Nolmark, Director of Volvo Research and Educational Foundation
