Castle Rock was founded in 1984 and remains a leader in the development, integration, deployment, and hosting of ITS (Intelligent Transportation Systems) solutions.

While we have been at the forefront of many cutting-edge ITS developments throughout our company’s history, the CARS and MODES platforms are now at the very heart of our business.  CARS is a modular system that provides 511, ATIS, open data sharing, and other traffic- and transportation-related functions. MODES is a platform that allows transit agencies of any size to create and maintain GTFS and GTFS-realtime data.

We continue to innovate in the field and are actively working with several of our clients in cutting-edge research areas, including ICM, Connected Vehicles, and Smart City integrations.

Castle Rock is a certified Woman Business Enterprise (WBE) and Woman-Owned Small Business (WOSB).
