摘要：	The San Diego Intermodal Transportation Management System (IMTMS) is a regional project consisting of the integration of six transportation modal management systems: the Intermodal Advanced Traffic Management System (ATMS(I)) for freeway management, the Regional Arterial Management System, Transit Management System, Commercial Vehicle Management System, Incident Response Management System for public safety systems and Advanced Traveler Information Management System for ATIS users. A regional communications network will be built (or leased) to support connection of the modal management systems. Systems connecting to this regional network will conform to Interface Definition Language specifications developed for the Southern California Priority Corridor Showcase network. Each of the modal management systems listed above has completed initial definition of user requirements accompanied by an intermodal flowchart that shows the flow of data between modes and within individual mode subsystems. The regional Transportation Management Center (Caltrans TMC) will be the network hub that integrates information from all the modes represented in the regional network. The regional TMC will also act as the point of integration of ATMS and ATIS information being exchanged among the four regions of the Priority Corridor: San Diego, Orange County, Inland Empire and Los Angeles/Ventura. The regional TMC contains several subsystems that act largely independently of each other – the primary subsystem relating to the regional intermodal network is the Caltrans Advanced Traffic Management System. Some of the more important decisions regarding intermodal operations include the following: · Arterial management will be decentralized to the individual agency level using a 2-tier approach: Tier 1 provides traffic signal coordination among jurisdictions using IP-based networking. Tier 2 adds ATMS functions to each city system such as CCTV and CMS control and freeway traffic surveillance. Tier 2 also adds an arterial travel time function. · Freeway/arterial coordination will be facilitated by the regional network and the technology to allow the exchange of real-time traffic data and the monitoring/control of field devices such as CMS’s and CCTV’s. Much of this effort will be institutional rather than technical in nature. · A joint transit/city traffic operations center has been proposed to integrate operations of the City of San Diego, San Diego Transit and San Diego Trolley. This will include a regional parking and event management subsystem focused on the new San Diego Padres ballpark being built in the downtown complex and the existing Qualcomm Stadium. · The transit management system will support multiple transit operators (2 bus, 1 light rail and 1 commuter rail) using separate but standardized transit functional modules, such as automatic vehicle location, dispatch, scheduling and on-board bus equipment.
