This report reviews the crash cost reduction factors for countermeasures currently listed in the Alaska Department of Transportation and Public Facility's Highway Safety Improvement Program (HSIP) Handbook (HSIPHB) and provides revised values based on a literature survey of research and references. In addition, crash cost reduction factors are proposed for the five treatments that are not currently listed in the HSIPHB, including cable barrier median barriers, pavement traction enhancement, flashing yellow arrow left turn indications, HAWK pedestrian signals, and concrete median barriers. There is also a section on practices by other state DOT organizations. Alaska HSIP data is evaluated for safety effectiveness and the report provides an analysis and recommendations for the HSIP post evaluation process. This project and report also included research of the effectiveness of Active Advance Warning Flashers (AAWF) and shoulder rumble strips based upon Alaskan crash experience.

TRB¿s National Cooperative Highway Research Program (NCHRP) Report 617: Accident Modification Factors for Traffic Engineering and ITS Improvements explores the development of accident modification factors (AMFs) for traffic engineering and intelligent transportation system improvements. AMFs, also known as crash reduction factors, are designed to provide a simple and quick way of estimating the safety impacts of various types of engineering improvements, encompassing the areas of signing, alignment, channelization, and other traffic engineering solutions.

Highway safety practitioners were given a significant new tool in 2010 with the publication of the AASHTO Highway Safety Manual. In the HSM, crash modification factors (CMFs) were provided to estimate the safety effects for a variety of treatments or countermeasures. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 352: Crash Modification Factors in the Highway Safety Manual: Resources for Evaluation provides the appendices to NCHRP Research Report 1029: Crash Modification Factors in the Highway Safety Manual: A Review.

Crash reduction factors are used to identify and prioritize the most effective safety improvement measures, and prioritize and allocate available resources optimally for a highway safety improvement project. Simple before-and after analysis does account for the regression-to-the-mean bias. This research employs an Empirical Bayes (EB) methodology that overcomes the regression-to-the-mean property that is encountered in traditional before-and after analysis. Traffic, geometric and crash data for both the treatment and comparison sites were collected from Ohio in developing the crash reduction factors. Using data collected from Ohio, the EB methodology was applied in developing crash reduction factors for the following improvement categories: add a two-way left turn lane, install a median barrier, flatten slope and remove guardrail, remove or relocate a fixed object, flatten vertical curve, providing highway lighting and close median opening.
