The Southern California Priority Corridor is one of four priority corridors nationwide, that will serve as a proving ground for testing advanced Intelligent Transportation System (ITS) technologies in the years to come. The Corridor consists of mostly urbanized areas of the six county regions of Ventura, Los Angeles, Orange, San Bernardino, Riverside and San Diego Counties. The area consists of over 150 cities including the major metropolitan cities of Los Angeles, Long Beach, San Diego, Pasadena, Anaheim, San Bernardino, and Riverside. Numerous ITS projects in the form of operational tests, and strategic planning studies are currently underway in the corridor. One such project is the Intermodal Transportation Management and Information System, known as "Showcase". The Southern California Priority Corridor's Showcase project represents a major attempt to demonstrate the benefits of ITS, through its coordination of intermodal traffic and dissemination of traveler information, involving multiple jurisdictions and encouraging public/private partnerships on a regional basis. Showcase's credo of "all modes and all roads", and its guiding principle "to develop an architecture that will provide an interoperable environment for all participants", sums up the corridor vision. The Showcase architecture will also provide initial integration points within each county to enable rapid deployment through its implementation strategy. Since Showcase is the first 5 years of a 20 year deployment of the Southern California Priority Corridor, it is crucial that the architecture is well engineered and far-sighted. In a seven step development process, the National ITS Architecture's Market Packages are used to guide the design of the Showcase architecture. The paper describes how Showcase has locked arms with the National ITS Architecture and in a stepwise manner is producing the fecund environment for the Southern Priority Corridor. |
