Crash Costs for Highway Safety Analysis (FHWA)

The Crash Costs for Highway Safety Analysis publication by FHWA provides guidance on effective practices for estimating the costs of crashes by severity for use in economic analyses. The document provides discussion around different approaches to estimating crash costs, the impacts of injury scale, crash type, and severity on unit costs, conversions between crashes, injuries, and vehicles, and other related topics. A synthesis of current state practices on determining and utilizing crash costs is also provided, helping to build an understanding of contemporary practices and what may be most suitable depending on the needs of an agency.

Model Inventory of Roadway Data Elements (MIRE)

MIRE is a listing and accompanying data dictionary of roadway and traffic data elements critical to safety management. MIRE provides the basis for what constitutes a robust data inventory, a critical need when using the new generation of safety data analysis tools and methods, including the HSM and related tools (IHSDM and SafetyAnalyst). There are a total of 202 elements in MIRE divided among three broad categories including roadway segments, roadway alignment, and roadway junctions. Click here for more information on MIRE.

Model Minimum Uniform Crash Criteria (MMUCC)

MMUCC is a minimum, standardized data set for describing motor vehicle crashes and the vehicles, persons, and environment involved. The Guideline is designed to generate the information necessary to improve highway safety within each state and nationally. This data set has 110 data elements, including 77 data elements to be collected at the scene, 10 data elements to be derived from the collected data, and 23 data elements to be obtained after linkage to driver history, injury and roadway inventory data.

Crash Data Improvement Technical Assistance Program (CDIP)

CDIP gives states a way to measure the quality of their crash database in terms of its timeliness, accuracy, and completeness as well as the consistency in the way agencies report the information. Other measures in the program examine the state's ability to integrate crash data with other safety databases and how the state makes the crash data accessible to users.
