The ACES (Automated. Connected. Electric. Shared) Mobility Coalition has announced its newly elected officers for 2026 and welcomed new public sector board members, further strengthening the coalition’s leadership as it advances autonomous, connected, electric, and shared mobility across the United States.

The newly appointed officers and board members represent a broad cross-section of public transportation agencies, local governments, and mobility innovators, reinforcing ACES’ public-sector-led, multi-stakeholder approach to advancing shared autonomous mobility that helps solve first- and last- mile problems, safety, congestion and sustainability issues, among others.

“The strength of the ACES Mobility Coalition has always been the practical, real-world experience our members bring to the table,” said Scott Belcher, Executive Director of the ACES Mobility 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. Their leadership will be critical as we enter a pivotal year focused on education, policy engagement, and scaling solutions that expand transportation access, improve safety, and support the evolving autonomous workforce.”

New Organizations and Public Sector Board Members

Cumberland Community Improvement District (CID) – Kim Menefee, Executive Director

The Cumberland Community Improvement District (CID), Georgia’s first CID, is one of the nation’s premiere models of public-private collaboration and how it can advance transportation access and connectivity for economic vitality. More than 190 commercial property owners voluntarily contribute additional property tax, which the CID strategically leverages to plan, fund, and deliver transportation, infrastructure, and other improvements that improve mobility and business growth throughout the Cumberland area. Today, Cumberland has a $26.6 billion annual impact on Georgia’s economy and is home to major entertainment venues and companies including the Atlanta Braves, Papa Johns, The Home Depot, Synovus, Comcast, and more.

Cumberland CID is a natural fit for the ACES Mobility Coalition because it is actively advancing shared autonomous mobility by moving beyond pilots and into permanent public transportation options for residents through its Cumberland SWEEP initiative, a 3-mile-plus multimodal path designed to improve connectivity for pedestrians, cyclists, and transit riders.

Cumberland CID and Cobb County were recently awarded a $6.6 million grant from the Federal Transit Administration’s Low or No Emission Vehicle (Low-No) Program to create the Cumberland Autonomous Mobility (CAM) Network along the SWEEP corridor, deploying a fleet of eight ADA-accessible autonomous shuttles that will enhance first- and last-mile access, improve quality of life, and integrate with the CobbLinc public transportation system operated by Cobb County. Expected to launch in 2027, the CAM Network positions Georgia as a national leader in integrating autonomous transit technology into a regional transportation system. The CAM Network will be delivered in partnership with fellow ACES Mobility Coalition member Beep Inc., which will serve as the technology and operations provider that will help integrate the autonomous shuttle service into CobbLinc.

Kim Menefee, Executive Director of Cumberland CID, joined the organization in 2019 and has led its efforts to partner with commercial investors, government officials, and stakeholders to advance key transportation and infrastructure projects in the region. Prior to joining the organization, she spent 25 years in senior leadership roles at WellStar Health System, Georgia’s largest not-for-profit health system.

MetroLINK – Ben Limmer, AICP, Chief Executive Officer/Managing Director

The Rock Island County Metropolitan Transit District, commonly known as MetroLINK, is the public transportation provider for the Illinois Quad Cities area serving Rock Island, Moline, East Moline, Silvis, Milan, Carbon Cliff, Hampton, and Colona. It operates a network of fixed-route buses running dozens of routes, seven days a week that serves nearly 3 million customers a year. This transit service connects people to jobs, education, healthcare, shopping, and other daily-life destinations helping to reduce traffic congestion and pollution, and providing mobility to people without cars. Beyond buses, MetroLINK offers ADA-compliant paratransit and special transportation services for riders with disabilities or with medical-transportation needs.

MetroLINK aligns closely with the mission of the ACES Mobility Coalition, through its significant investments in clean transit, and industry leadership in deploying battery-electric buses and electric charging infrastructure.

Ben Limmer, AICP, Chief Executive Officer/Managing Director, is recognized in the public transportation industry as a visionary, transformative, fiscally responsible, and collaborative leader. He took the helm of MetroLINK in 2025 to provide strategic, financial, and operational leadership for the organization. Most recently, Limmer served as the Chief, Public Transportation for the Connecticut Department of Transportation, leading one of the nation’s most dynamic multimodal public transportation systems.
