Book Description
This study developed a new, better procedure for assessing widespread geographic effects resulting from the use of safety treatments. Most currently used statistical methods for countermeasure evaluation assess the spot or local changes that result from the new treatment. The effects of the treatment on the entire system or near-by contiguous links are seldom evaluated. The new approach is ideal for applications where large quantities of data reside in a PC computer format. Incorporated in the methodology are known procedures for determining if regression-to-the-mean (RTM) problems exist and how those problems can be minimized when they are present. A previous research study developed a computer program - Bayesian Estimation of Accidents in Transportation Studies (BEATS) - that identifies and corrects RTM bias in highway safety studies. Step-by-step guidelines were developed on how to plan and use the new procedure to evaluate highway safety studies. The guidelines describe what are adequate sample sizes, how to identify RTM problems, and how computerized data analysis procedures can be used.

Book Description
TRB Special Report 254 - Managing Speed: Review of Current Practices for Setting and Enforcing Speed Limits reviews practices for setting and enforcing speed limits on all types of roads and provides guidance to state and local governments on appropriate methods of setting speed limits and related enforcement strategies. Following an executive summary, the report is presented in six chapters and five appendices.
Roadside Design Guide

ISBN: 9781560510314
Category : Bridge railings
Languages : en
Pages : 352
Book Description
This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."
