Iowa’s LRS Implementation of NCHRP 20-27 model. Which separates business data from the location components of linear features (roads, navigable rivers, railroads, pipelines, etc.).

AASHTO’s Technology Implementation Group – or TIG – scans the horizon for outstanding advancements in transportation technology and invests time and money to accelerate their adoption by agencies nationwide. Each year, TIG selects a highly valuable, but largely unrecognized procedure, process, software, device, or other innovation that has been adopted by at least one agency, is market ready and is available for use by other interested agencies. Guided by the vision of "a culture where rapid advancement and implementation of high payoff, innovative technologies is the expectation of the transportation community," TIG’s objective is to share information with AASHTO member agencies, local agencies, and their industry partners to improve the Nation’s transportation system.

Many technical reports have been completed about developing and integrating a Linear Referencing System (LRS) within a state transportation agency. The magnitude of costs related to the 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 expected benefits. The Value Analysis (VA) Report will help the states by providing credible quantitative and qualitative benefits obtained from a s state’s investment as well as sample costs and requirements for implementing and maintaining a Multi-Level Linear Referencing System (MLLRS). The use of the word “baseline system” throughout the report represents the minimum requirement for a fully functioning MLLRS. The use of the term “optional functional elements” refers to supplemental elements that will improve the baseline MLLRS.
