Roadway Safety Data Program (RSDP)
The FHWA Office of Safety established the Roadway Safety Data Program (RSDP) to advance State and local safety data systems and safety data analyses. The RSDP is an overarching program of roadway data improvement efforts that is cohesive, well-informed, and visionary enough to not only serve as the basis for near-term projects but also anticipate and plan for mid- and longer-term improvements.
A data-driven safety program combines crash, roadway inventory, and traffic data for systemic identification of infrastructure safety improvements. State crash data systems are advancing with the electronic capture of crash data, electronic transfer of information to central crash databases, and the identification of performance measures to assess crash data quality. Roadway data, however, have not been as thoroughly or uniformly documented or assessed. The RSDP will contribute to the evolution of more robust roadway data systems and advance data-driven safety capabilities.
MAP-21 Guidance on State Safety Data Systems: This guidance clarifies (1) State safety data capabilities to satisfy the "Moving Ahead for Progress in the 21st Century Act" (MAP-21) (P.L. 112-141), and (2) the safety data collection, integration, improvement, and analysis activities eligible for HSIP funding.
Model Inventory of Roadway Elements (MIRE): The MIRE is a listing of roadway and traffic data elements needed to support advanced safety analyses.
MIRE FDE Cost Benefit Estimation – Report No FHWA-SA-13-018: This report estimates the potential cost to States in developing a statewide Linear Referencing System and collecting the Minimum Inventory of Roadway Elements, Fundamental Data Elements, on all public roadways. The expected benefit is that collecting additional roadway and traffic data and integrating those data into the safety analysis process will improve an agency's ability to locate problem areas and apply appropriate countermeasures, hence improving safety.
State Safety Data Capability Assessment: FHWA Office of Safety initiated the Roadway Safety Data Capability Assessment to better understand the current status of State safety data systems.
Crash Data Improvement Program (CDIP): The CDIP provides States with a means to measure the quality of the information within their crash database.
Roadway Data Improvement Program (forthcoming): The Roadway Data Improvement Program (RDIP) is a program to help transportation agencies improve the quality of their roadway data to support their safety initiatives.
Highway Safety Manual (HSM) Implementation: The FHWA Office of Safety supports various HSM implementation efforts.

MIRE Data Collection Guidebook. The MIRE Data Collection Guidebook builds upon the MIRE, Version 1.0 document to identify issues State's should be cognizant of when collecting information on specific MIRE elements. The Guidebook discusses methods of collecting the MIRE elements and potential limitations of those methods. It provides data managers and collectors with information regarding techniques for collecting MIRE data elements that potentially will allow them to collect the elements more efficiently.
MIRE Management Information System Lead Agency Data Collection Report. The Lead Agency Data Collection Report presents the findings from an effort to assist two States to expand their roadway inventory data collection to include MIRE intersection data elements. The development of this information into their databases was intended to facilitate the use of this information to use more advanced analytic methods. The report documents two different methods of data extraction used by the two pilot states. The implications from this effort may lead to more effective and efficient methods of increasing the collection and use of MIRE by State and local transportation agencies. Further, these results may better assist States in complying with the guidance and requirements of the Moving Ahead for Progress in the 21st Century (MAP-21) legislation.
MIRE Element Collection Mechanisms and Gap Analysis. The Element Collection Mechanisms and Gap Analysis Report presents the findings of an effort to 1) explore existing and emerging data collection technologies, and 2) to narrow the gaps between the elements in the MIRE listing and the current data available from transportation agencies' inventories and supplemental databases. This report provides data managers and data collectors with potential techniques for advancing future data collection of roadway and traffic inventory data.
Performance Measures for Roadway Inventory Data. The Performance Measures Report builds upon NHTSA's Model Performance Measures for State Traffic Records Systems Report and identifies issues to be considered and performance measures to assess the quality of the roadway and traffic data. This report provides data managers and collectors with refined techniques for assessing the quality of the roadway and traffic data inventory data they collect and maintain.
Development of a Structure for a MIRE Management Information System. The Structure Report identifies issues State's should be cognizant of when collecting, correcting, and maintaining information for a safety management system. The report presents a conceptual model that identifies the business functions a state is likely to need from a safety management system. This document provides data managers with information and issues they should address in establishing or improving an integrated safety data file structure to enhance the safety performance of the state's roadways.
MIRE MIS – Feasibility of a Model Inventory of Roadway Elements Management Information System. The Feasibility Report serves as a summary document for that activities conducted as part of the MIRE MIS program. This report provides information about each of the component projects and the findings and implications of the effort.
The Exploration of the Application of Collective Information to Transportation Data for Safety White Paper. The White Paper explores the technique of collective information as a means of gathering data needed for transportation safety. Collective information is a process of assembling or gathering information on a subject through the use of a large, disperse and potentially uncontrolled group of individuals. The White Paper also examines current uses of collective information gathering and potential next steps for this process to support the collection of transportation data.
Integrating MIRE – Better Data for Better Decisions to Save Lives. The Integrating MIRE Brochure highlights the major findings from the MIRE MIS program. It includes information about data collection, integration and management, and about measuring data quality.
