Book Description
The objective of this study was to establish a set of written guidelines identifying traffic and road conditions where No U-Turn and No Left Turn signs should be installed. The effect of these signs on traffic safety was also investigated. A questionnaire was sent to all Virginia Department of Transportation District Traffic Engineers, selected city and county traffic engineers in Virginia, and selected state, city and county traffic engineers outside of Virginia, asking about their current procedures for installing No U-Turn and No Left Turn signs. Eight signalized intersections where these signs had been installed were studied to determine the effect of the signs on left-turn and U-turn related accidents. The signs reduced left-turn and U-turn related accident rates an average of 63 percent for the restricted movement, and 66 percent for the intersection. The decrease in accident numbers paralleled the decrease in accident rates, a 59 percent reduction for the restricted movement and a 62 percent reduction for the intersection. Based on the results from the questionnaire and a literature review, guidelines were established to aid traffic engineers in determining where to install these signs.

Book Description
"The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--P. xxiii.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Description
The New Official K53 Manual is a comprehensive and effective guide to passing your Learner’s Licence and K53 Driver’s Licence – first time. Covering both light and heavy motor vehicles, and motorcycles, each chapter discusses the knowledge and skills expected of you. The learner’s section explains the K53 Defensive Driving principles, road signs and the rules of the road, with questions and detailed answers to test your knowledge. At the end of this section there is a test similar to that compiled by traffic departments. The driver’s section explains how candidates are tested and what examiners look out for, with step-by-step instructions on how to perform every manoeuvre in both the yard and road tests. With detailed, full-colour illustrations throughout, this is the definitive manual for both the learner’s and driver’s tests.
