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.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

Book Description
The Commitment-Reflectivity Circumplex (CRC) model of religious orientation is introduced and the results from a series of model testing experiments are reviewed. The CRC model was developed through a series of studies in the United States and Romania and was created in an effort to reduce the theoretical and empirical difficulties associated with the traditional Allportian religious orientation models and measures. Toward this end, the difficulties associated with the Allportian religious orientation models are reviewed, along with how the CRC model attempts to address them. Next, the CRC model is introduced and a list of its predictions are given and compared to those of the Allportian models. The results of 10 model testing studies using multidimensional scaling are then reviewed. In these studies, the CRC model, which posits that all religious orientation can be located along dimensions of commitment (importance) and reflectivity (complexity), is found to be more accurate than the Allportian models in both the U.S. and Romania. Based on these studies, the meaning and interpretation of the Allportian measures are reviewed and new interpretations are suggested. Lastly, the relationships between religious orientation, mental health, personality, ideology, and prejudice are explored. In every area, the CRC model, and the measures based on it, show superior predictive abilities to traditional approaches in both the United States and Romania.

Book Description
This guide replaces the 1984 publication entitled An Informational Guide for Roadway Lighting. It has been revised and brought up to date to reflect current practices in roadway lighting. The guide provides a general overview of lighting systems from the point of view of the transportation departments and recommends minimum levels of quality. The guide incorporates the illuminance and luminance design methods, but does not include the small target visibility (STV) method.
