Data and Analysis Tools
These tools have been designed to assist practitioners understand safety problems on their roadways, link crashes to their roadway environments, and select and apply appropriate countermeasures.
SafetyAnalyst
Provides state-of-the-art analytical tools for use in the decision-making process to identify and manage a systemwide program of site-specific improvements to enhance highway safety by cost-effective means.
Crash Reduction Factors
This is the percentage crash reduction that might be expected after implementing a given countermeasure at a specific site.
Highways for LIFE
All about building faster, safer, with better quality, less cost and causing less work zone congestion.
Market Ready Technologies & Innovations for Improving Roadway Safety
A list containing safety related technologies and innovations that the Federal Highway Administration (FHWA) believe warrant special attention.
Red Light Cameras
This two-page fact sheet provides an overview of the three types of cameras most often used for red light enforcement.
Interactive Highway Safety Design Model
Includes all recently published materials on IHSDM in online and/or hard copy format. Past published materials, denoted as archive, are also available; these materials are somewhat dated due to IHSDM's evolving nature, but may still contain information of interest to serious researchers. Some publications are available only for purchase from the National Technical Information Service (NTIS).
National Data Model
The National Model for the Statewide Application of Data Collection and Management Technology to Improve Highway Safety is a program for sharing information, resources, and technologies to improve highway safety.
Traffic Control Devices
Defines the standards used by road managers nationwide to install and maintain traffic control devices on all streets and highways.
Intelligent Transportation Systems
Advanced safety technologies, especially Intelligent Transportation Systems (ITS), are being actively researched, developed and applied to improve highway safety in the United States, and in other countries.
Pedestrian & Bicycle Safety Tools
Variable Speed Limit Systems
Speed limits that change based on road, traffic, and weather conditions.
Retroreflectivity
The scientific term that describes the ability of a surface to return light back to its source. Retroreflective signs and pavement markings bounce light from vehicle headlights back toward the vehicle and the driver's eyes, making signs and pavement markings visible to the driver.
Law Enforcement Technology Clearinghouse
A clearinghouse for identifying and documenting as many automation projects as possible on technology used in the collection of crash data.
Road Safety Audits
The formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team.
Contacts
Office of Safety staff and primary work responsibilities.
USLIMITS
USLIMITS Expert Speed Zoning Advisor
Resurfacing Safety Resource Allocation Program (RSRAP)
Software developed to allow highway agencies to implement a process that selects a program of safety improvements, to be made in conjunction with resurfacing projects, that maximizes traffic safety and operational benefits resulting from the program.
