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."

Book Description
This publication sets out the statutory requirements for signing, lighting, and guarding at street works and road works. This is the core reference manual for utility companies, local authorities, street work contractors and others whose day-to-day business involves street works (works by statutory undertakers and other utility companies etc) and road works (works to maintain or repair road infrastructure). The code, which covers all of the UK and includes national variations, is now compulsory for highway/road authorities in England, Wales and Northern Ireland. It applies to all single carriageway roads and dual carriageways with a speed limit of 40 mph or less. The code is now divided into three parts: Basic Principles, Operations, and Equipment and Vehicles; site layout diagrams have been redrawn to make them easier to understand. There is: increased emphasis on using risk assessment and guidance on what to consider in such assessments; strengthened guidance on providing for pedestrians and cyclists and new guidance on traffic control measures related to road closures, one-way working and temporary road obstructions; enhanced advice on other traffic control measures including works near tramways and railways, and mobile/short duration works; and updated advice on high visibility clothing and the signing and conspicuity requirements for work vehicles. Effective from 1 October 2014 when it will supersede the 2001 edition (ISBN 9780115519581).

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
Driving is a privilege and not a right. Drivers must drive responsibly and safely, obey traffic laws, and never drink and drive. Finally, make sure that you and your passengers are properly buckled up - it's the law! Today's vehicles are loaded with technology that was unheard of even a decade ago. Systems that warn when you are drifting from your lane, assist you in parallel parking, automatically brake in emergency situations and provide 360 degrees of vision around the vehicle via a camera are becoming standard, even on moderately priced vehicles. As remarkable as these leaps in automotive technology are, the truth is that the most important safety feature in any vehicle remains you as the driver. Therefore, it is to your benefit to continue improving and expanding your knowledge of traffic laws and safe driving practices. Driving is a privilege. Once you have been issued a driver's license, you have the responsibility to continually demonstrate the skill and knowledge to drive safely. Whether you have been behind the wheel for decades or are just starting to venture out, driving is a discipline that requires judgment, knowledge, physical and mental self-awareness, and practice. "What Every Driver Must Know" is an excellent resource for assisting you on this lifelong journey.

Book Description
The primary objective of this research was to systematically review past studies on rear end crashes, examine strategies for reducing rear end crashes on both freeway and non freeway facilities, and develop a set of rear end crash reduction strategies for use in Ohio, which will be appropriate for various traffic engineering solutions, operations and ITS improvements. Accordingly, this study conducted an extensive review of past literature related to rear end crashes and strategies to reduce them. A determination of specific strategies for a road safety improvement program requires an understanding of probable crash reduction capabilities for various geometric, operational and environmental factors on the roadways. Studies of crash reduction strategies have usually focused on before-and-after comparisons of specific locations or conditions. Based on the data provided by the Ohio Department of Transportation, this study attempted to examine the crash reduction capabilities for signalized intersections, unsignalized intersections, freeways and non-freeways where countermeasures were implemented. An attempt was made to compute crash reduction factors for rear end collisions for these roadway facilities. However, this task could not be performed because of the severe limitations in the ODOT countermeasure and roadway site data. In response to the researchers' request for additional data, ODOT decided not to proceed ahead with this research as it required the dedication of district resources that were not currently available. It was believed that breaking the project into smaller, more manageable pieces, would not yield results that would be statistically significant. There were also several national projects underway which would limit this project's benefits. In view of these circumstances, ODOT decided to terminate the contract for this project and all work stopped.

Book Description
Expectancy relates to a driver's readiness to respond to situations, events, and information in predictable and successful ways. This report describes the concept of driver expectancy in the context of the driving task, and provides examples of expectancy and expectancy violations. It includes a procedure for identifying general and specific expectancy violations to enable engineers to develop remedial treatments to deal with expectancy problems.

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.
