Safety Resource Allocation Programs and Input Processor: User's Manual

摘要

The report is the users manual for the SRAP (Safety Resource Allocation Programs) microcomputer program package on IBM-PC and compatible microcomputers. The SRAP package contains three computerized methodologies--incremental benefit-cost analysis, integer programming, and dynamic programming--developed by the Federal Highway Administration (FHWA) to aid highway safety planning decisions by prioritizing projects based on their costs and benefits. The three models maximize total net accident savings under a given budget constraint by selecting the optimal mix of accident locations and the preferred countermeasure alternatives at those locations. Also included in SRAP is an interactive input processor to assist users in creating and modifying input data files. The input processor, through a menu-driven, full-screen editing interface, relieves the user of the 'clerical' requirements of data coding, such as card types, card order, data fields, and data formats.
