This book, which is intended for educators, students, consultants, highway engineers and scientists, provides a practical procedure for the design of highways for maximum safety. On the basis of original research and data amassed over more than two decades, it originates vital criteria for safe design and shows how best to achieve the lowest possible accident risk. A methodology is incorporated for evaluating planned or existing highway alignment designs with respect to their expected impact on traffic safety. The designer is enabled to evaluate alternative designs in terms of the relative danger they will impose on the travelling public. The operations engineer is enabled to prioritise highway improvement strategies based on the expected improvement to traffic accident patterns. Engineers are enabled to predict quantitatively the accident consequences of their proposed or existing alignments by using this process and employing these criteria. Application of the methodology is intended to achieve design consistency, operating speed consistency and driving dynamic consistency. (Author/publisher)
