This Regional ITS Architecture is a roadmap for transportation systems integration in the Longview-Kelso-Rainier metropolitan area. The architecture was developed through a cooperative effort by the region's transportation agencies, covering all modes and all roads in the region. Developed and maintained by the Cowlitz-Wahkiakum Council of Governments (CWCOG) on behalf of all of the transportation providers and users in the region, it represents a shared vision of how the systems will work together in the future, sharing information and resources to provide a safer, more efficient, and more effective transportation system for travelers in the region. The architecture provides an overarching framework that spans all of the region's transportation organizations and individual transportation projects. Using the architecture, each transportation project can be viewed as an element of the overall transportation system, providing visibility into the relationship between individual transportation projects and ways to cost-effectively build an integrated transportation system over time.

The purpose of this regional ITS architecture web site is to encourage use of the regional ITS architecture and gather feedback so that the architecture is used and continues to reflect the intelligent transportation system vision for the region. The menu bar at left provides access to the stakeholders, the transportation systems in the region (the Inventory), the transportation-related functions that are envisioned, and the existing and planned integration opportunities in the region.

This website was generated using the RAD-IT database that contains the complete baseline architecture definition. In addition to the database and website, the architecture also includes two documents that define how it is used and maintained:
