WSDOT has two paths for identifying needs. The programmatic approach is a technical process. In preservation, this process is used for assets like paving, structures, unstable slopes, high crash locations, etc. Our Pavement Management System, the Bridge Preservation system, and the Unstable Slopes Management System are examples of the programmatic preservation programs. Other programmatic approaches include, for example, the safety program based on data analysis and principles of systematic safety.
The other approach for identifying needs is by corridor. As this relates to mobility and economic vitality performance the process has more public engagement for identifying related needs. One of the tools for identifying needs by corridor is the Corridor Sketch initiative, which is a set of planning activities. For more information about this tool, visit the Corridor Sketch Initiative website.
Corridor needs may also be identified through data analysis or through a state modal plan that incorporates local and regional plans. For example, a systematic safety analysis and crash data may identify the need for infrastructure changes, or a modal plan may provide information on needs and priorities for programming and projects.
Identifying needs applies to certain performance measures and metrics, as summarized in the linked tables below. Note that not all system needs are focused on mobility and economic vitality. Additional performance measures and metrics will be developed to evaluate how WSDOT projects advance WSDOT’s goals around the environment, preservation, safety, and stewardship.
