TMD began in 1988 in Dallas and over the next decade grew into a San Diego-based corporation focused on all things transit. TMD was an early leader in embracing and developing new transit industry best practices in GIS, new data, and advanced analytics, computerized scheduling, transit priority, and public mobility beyond just buses and trains.

As we enter our fourth decade, TMD continues to deliver specialized transit solutions using rigorous, data-driven methods and strategic application of best practices. Much of our business is driven by ongoing relationships with transit agencies seeking a variety of on-call planning and technical support services customized to their unique needs.
