The Contra Costa Transportation Authority (CCTA) and Tri Delta Transit are marking another milestone in the innovative East Contra Costa County Dynamic Personal Micro Transit (DPMT) Project. Today, CCTA and Tri Delta Transit are announcing a partnership with East County Connection Partners, LLC (ECCP), made up of transportation innovators Glydways and Plenary Americas; and lead construction contractor Flatiron.

The DPMT Project is a multi-city, on-demand transit option designed to meet the diverse mobility needs of the 347,896 residents who live in Eastern Contra Costa County. ECCP will help bring the vision of a safe, on-demand, single-party, transportation system into reality with its zero-emission, autonomous, four-person Glydcars. These electric vehicles travel in narrow, dedicated elevated or at-grade guideways, making more efficient use of space, substantially cutting operational costs, and providing a sustainable option that aligns with local, regional, and state emission reduction goals. The Glydcars are designed with convenience in mind, with enough space for passengers to easily travel with their luggage or bikes. The vehicles are also fully compliant with the Americans with Disabilities Act and provide enough room to comfortably fit a wheelchair.

This new, fare-based transit solution will help enhance transit accessibility in East County by improving connections to existing options such as BART and local bus services. When the project is successfully completed, the transport will help to alleviate the increasing congestion on State Route 4 (SR-4) and major arterials in East County.

In Spring 2021, the cities of Antioch, Brentwood, Oakley and Pittsburg completed the East County DPMT Feasibility Study (Study) to support a potential micro-transit deployment with Autonomous Vehicles (AVs) in East Contra Costa County. Subsequently, the CCTA and Tri Delta Transit partnered to evaluate the potential deployment of the East County DPMT project.

ECCP specializes in a revolutionary on-demand public transportation system. CCTA in partnership with Tri Delta Transit, selected ECCP as the preferred vendor for the DPMT project after a comprehensive evaluation process. CCTA, Tri Delta Transit, and ECCP will work together to deliver an initial viable segment of the larger project through a unique public-private partnership (P3).

“We’re very excited about this project and believe it will significantly improve the quality of life in our community,” said CCTA Board Chair Federal Glover. “It’s a bold step towards a more sustainable and accessible future for Contra Costa.”

To actualize that future, CCTA and Tri Delta Transit determined last year that engaging a private sector partner to collaborate with would be the most beneficial strategy. The P3 approach has proven to be a highly efficient agreement, allowing for smoother delivery and deployment of transportation projects. P3s unlock the ability to quickly mobilize the resources required for state-of-the-art, effective, and sustainable transportation solutions, such as the DPMT project.

“This partnership is a significant milestone for us,” said Tri Delta Transit Board Chair, Lamar Thorpe. “By working with ECCP, we can leverage their expertise in innovative transportation technologies to better serve East County residents.”

The partners will also collaborate to pursue funding for implementation of the initial segment. More information about the DPMT project is available here.

Glydways is an automated personal rapid transit system (PRT) that provides on-demand, high capacity service moving riders in purpose-built autonomous vehicles on narrow and lightweight fixed guideways. The system has a fundamental focus on the rider experience – on-demand, direct to destination trips, single-party (4 people) – to attract more ridership out of cars and onto transit. The net results are small, lightweight vehicles that operate extremely efficiently at all times of day, significantly less intrusive and costly infrastructure to build, and sustainable economics and environmental impact. Glydways can safely and reliably move thousands of people per hour in fleets of small battery electric autonomous vehicles by creating an interconnected and intelligent system of omnipresent infrastructure monitoring systems and communications systems that work with the vehicles to create a highly controlled operational environment. This approach allows Glydways to solve the many mobility challenges where rail is not feasible or affordable but requires more throughput than mixed-traffic or protected lane on-road modes.

Glydways, which was born into public transit at GoMentum Station with the vision of addressing equity and congestion and has received significant hands-on field reviews and user testing feedback from various East Contra Costa County stakeholders. Glydways, formerly known as Wayfarer, was founded in 2016. Learn more at
