                Background Report: Guidance for Roadway Safety Data to Support the Highway Safety Improvement Program
**Description:**
        In 2011, the Federal Highway Administration (FHWA) Office of Safety released a guidance memorandum on the fundamental roadway and traffic data elements that States should be collecting and incorporating into their safety analyses to support their Highway Safety Improvement Program (HSIP). The purpose of this background report is to provide information on why and how the guidance was developed, estimates of the costs of data collection, safety analysis tools and methods, and performance measures that should be implemented to achieve quality safety data.
