RSAP is an encroachment-based computer software tool for cost-effectiveness evaluation of roadside safety improvements originally developed under NCHRP Project 22-9(1). Subsequently, some improvements were made, bugs corrected and patches installed under NCHRP Project 22-9(2). A third NCHRP project, 22-9(3) was initiated but never completed. Various releases of RSAP have been distributed with the AASHTO Roadside Design Guide (RDG) since the 2002 edition. This version of RSAP (i.e., RSAPv3) was developed under NCHRP Project 22-27 which was completed in 2012. The analytical model behind the encroachment-based approach uses a series of conditionally independent probabilities representing vehicle roadside encroachment events, the conditional probability of a crash given a roadside encroachment has occurred, the probable severity of crashes that are likely to occur and the expected benefit cost ratios of various roadside design alternatives.

Based on the sequential nature of these conditional probabilities and the assumption that they are independent, the RSAPv3 is basically structured into the following four modules, similar to its predecessors: Encroachment module, Crash prediction module, Severity prediction module and Benefit-cost module.

Geometric Design Title 23 USC 109 provides that design standards for projects on the (NHS) must be approved by the Secretary of the U.S. Department of Transportation in cooperation with the State highway departments. The Secretary has delegated this authority to the Federal Highway Administrator. The State highway departments, working through the American Association of State Highway and Transportation Officials () develop design standards through a series of committees and task forces.

FHWA contributes to the development of the design standards through membership on these working units, sponsoring and participating in research efforts, and many other initiatives. Following development of the design standards, FHWA uses a formal rulemaking process to adopt those it considers suitable for application on the NHS.
