Commercial Wholesale Web Portal (CWWP)


The Commercial Wholesale Web Portal (CWWP) is designed to assist commercial and media Information Service Providers (ISPs) requesting and receiving traveler information generated by the California Department of Transportation (Caltrans).  Caltrans recognizes ISPs are considered experts in media and customer needs, and are better able to widely distribute travel information to businesses and the public.

Caltrans anticipates ISPs will use the information made available through the CWWP to support Caltrans’ mission to “provide a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability.”  Caltrans intends to maximize the widespread distribution of travel information, providing travelers with access to real-time travel information to make informed choices on transportation modes and routes.

The CWWP standardizes and ensures all ISPs have equitable access and standardizes ISP registration.
