ICMS Description

The ICMS will be a system that consists of three major subsystems:

* System Services, consisting of systemwide functions of Data Management, System Management, and Life Cycle Support;
* IMTMS, an existing data acquisition and dissemination network within the San Diego region; and
* Decision Support System (DSS), a new capability that provides the integration of event management, multi-agency collaboration tools, multi-modal response plans, and impact assessment (modeling) to the existing IMTMS network.

The IMTMS subsystem is, in turn, connected to a number of existing and planned external systems in the region (shown in Figure 2‑1) that provide static and dynamic data on the condition of the region’s transportation networks. The IMTMS system also provides a degree of shared changeable message signs (CMSs) and closed circuit television (CCTV) control, data processing, and information display capabilities that will be enhanced by the ICMS development process.

I-15 ICMS functions will be developed for extensibility and adaptability to other corridors in the San Diego region. Figure 2‑2 provides a preliminary architectural view of ICMS and its component subsystems.
