For additional information on safety-related data collection and analysis, see the following resources:
NCHRP Report 500 Series: Guide for Implementation of the AASHTO Strategic Highway Safety Plan, Volume 19: A Guide for Collecting and Analyzing Safety Highway Safety-related data.
This guide was produced to assist State and local users in locating and analyzing pertinent safety-related data for use in their planning effort for any of the 22 emphasis areas of the AASHTO Strategic Highway Safety Plan. It provides analytical methods that can assist safety analysts in choosing and targeting safety improvement strategies and it provides guidance on sources of safety-related data, the procedures for choosing the best strategies and countermeasures within a given emphasis area, and targeting those strategies to either roadway locations or road-user subgroups.

Model Minimum Uniform Crash Criteria (MMUCC) Guideline
The Model Minimum Uniform Crash Criteria Guideline (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.

FHWA Crash Data Improvement Program (CDIP)
The CDIP is intended to provide States with a means to measure the quality of the information within their crash database. It is intended to provide the States with metrics that can be used to establish measures of where their crash data stands in terms of its timeliness, the accuracy and completeness of the data, the consistency of all reporting agencies reporting the information in the same way, the ability to integrate crash data with other safety-related databases, and how the State makes the crash data accessible to users. Additionally, the CDIP was established to help familiarize the collectors, processors, maintainers and users with the concepts of data quality and how quality data helps to improve safety decisions.

FHWA Work Zone Traffic Analysis
Links to reports, guidelines, examples, tools, articles, and webinars on analyzing and understanding various work zone impacts are available at this FHWA website. This information is intended to assist practitioners with determining appropriate mitigation strategies to use during project planning and design, and to include in their transportation management plans.

FHWA Work Zone Performance Measurement
Links to useful resources to assist practitioners at the National, State, and local levels with tracking and analyzing performance measures are available at this FHWA website. These resources include the following: Work Zone Self- Assessment tool, Process Review Toolbox, Performance Measurement Development, Performance Measurement Examples, and I-95 Corridor Coalition Performance Measures Course.

AASHTO Highway Safety Manual
The American Association of State Highway Transportation Officials (AASHTO) Highway Safety Manual (HSM) provides practitioners with information to facilitate roadway planning, design, operations, and maintenance decisions. AASHTO's webpage provides links to HSM-related tools as well as recorded training events that can be viewed free of charged providing individuals with an introduction to the HSM and how it can be used.

Crash Modifications Factors (CMF) Clearinghouse
Crash Modification Factors (CMFs) provide practitioners a method to quickly estimate the expected number of crashes after implementation of a crash countermeasure. The USDOT's CMF Clearinghouse contains a wealth of information CMFs, searchable by countermeasure category, crash type, crash severity, and roadway type. In addition, the clearinghouse provides practitioners the ability to submit and share CMFs documented through studies in their State.

FHWA Work Zone Data Examples Page
FHWA maintains a webpage on relevant work zone data examples to assist agencies in developing their own methods of data collection and analysis. In addition to the State examples, this webpage includes guidance and technical resources on work zone data collection and analysis, including webinar recordings, reports, and training information.

AASHTO/FHWA Domestic Scan on Work Zone Data Collection, Assessment, and Performance Monitoring
This report highlights a domestic scan held by AASHTO and FHWA in March 2010 that investigated how 14 State agencies are planning for, monitoring, and managing work zone performance. Also included in this report are key recommendations to develop and improve work zone data collection and analysis.
