Many technical reports have been completed about developing and Many technical reports have been completed about developing and integrating a Linear Referencing System (LRS) within a state integrating a Linear Referencing System (LRS) within a state transportation agency. The magnitude of costs related to the transportation agency. The magnitude of costs related to the development of a LRS and the commitment required by an agency can development of a LRS and the commitment required by an agency can be overwhelming, especially if there are no data to support the costs or be overwhelming, especially if there are no data to support the costs or expected benefits. The Value Analysis (VA) Report will help the states expected benefits. The Value Analysis (VA) Report will help the states by providing credible quantitative and qualitative benefits obtained from by providing credible quantitative and qualitative benefits obtained from a s state’s investment as well as sample costs and requirements for a s state’s investment as well as sample costs and requirements for implementing and maintaining a Multi-Level Linear Referencing System implementing and maintaining a Multi-Level Linear Referencing System (MLLRS).
