Book Description
Arizona's experience, with the 65 mile per hour speed limit is presented in terms of driver behavior and accident experience. The speed limit on Arizona's rural Interstate was raised to 65 miles per hour on April 15, 1987. Driver behavior is presented in terms of the speeds which motorists actually drive on the rural Interstate. Before and after data are presented from the last quarter of 1983 through the first quarter of 1988 Vehicle speeds increased by only about three miles per hour or less during the four quarters following the speed limit increase. A five year history of Interstate accident data --1983 through Spring 1988 is presented which provides a before and after comparison. Total accidents, fatal accidents, and injury accidents information is presented. Accident rate information is presented to account for the effect of increasing vehicle miles of travel. Accident data on the urban Interstate are presented for comparison purposes.

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).
