This guide revises and updates the 2002 second edition of the Austroads Road Safety Audit guide. It provides a comprehensive introduction to the road safety audit process. Easy to read and implement, the guide is suitable for use by any person with a responsibility for, or an interest in, road safety.Designed for use by road safety and traffic engineers, police, academics, local, provincial, state and national government officers, clients, students, researchers, consultants and many others, the guide provides both a comprehensive overview to, and application of, the road safety audit process. Clear details of the audit process are provided, together with a number of audit case studies. The guide includes chapters on legal liability, costs and benefits, the audit process, safety principles and technical issues which need to be considered in road safety engineering. The guide includes updated checklists for use in assessing road designs and inspecting project sites at the different stages of a project's development. These checklists may be printed off from the electronic version of the guide for use in the field.

  • Inputting road safety engineering skills at the start: an alternative to a feasibility stage audit
  • This process does not negate the need for an independent road safety audit at later stages of design. A road safety engineer who becomes involved directly with a project’s design can be as prone as any other professional to missing issues through famili
