The ACES Mobility Coalition has appointed its 2026 leadership team and added two public sector organizations to its board. The two new member organizations join the coalition’s public sector board are: Cumberland Community Improvement District (CID), represented by executive director Kim Menefee; and MetroLINK, represented by CEO and managing director Ben Limmer.
The ACES Mobility Coalition is a public sector-led alliance of government agencies, private companies, and academic organizations working to advance autonomous, connected, electric, and shared mobility solutions. The coalition focuses on deploying shared autonomous vehicles to address first- and last-mile transportation gaps, improve safety, reduce congestion, and enhance sustainability in communities across the United States.
Greer Johnson Gillis, senior vice president and chief infrastructure & development officer at Jacksonville Transportation Authority, will serve as president. Jim Derwinski, CEO of Metra, takes the vice president role, with Joe Moye, vice chair of Beep Inc.’s board, as second vice president. Kerri Stewart, chief strategy officer at Miller Electric Company, becomes treasurer, while Frank Martz, city manager of Altamonte Springs, assumes the secretary position. Tim Haile, executive director of Contra Costa Transportation Authority, continues as immediate past president.
“The strength of the ACES Mobility Coalition has always been the practical, real-world experience our members bring to the table,” says Scott Belcher, executive director of the coalition. “Our newly elected officers and newest board members represent agencies and organizations that are not just talking about shared autonomous mobility – they’re deploying it, integrating it into public transportation systems, and proving its value to communities every day.”
Cumberland CID manages transportation improvements in Georgia’s Cumberland area through public-private partnerships. The organization recently secured $6.6 million in federal funding to deploy eight autonomous shuttles along a multimodal corridor, integrating with Cobb County’s transit system. The service is expected to launch in 2027 with Beep Inc. providing technology and operations support.
MetroLINK operates public transit across Illinois Quad Cities communities, serving nearly 3 million passengers annually through fixed-route buses and paratransit services.
