This manual clusters all the knowledge about road safety. It is aimed, on the one hand, at students and lecturers of traffic engineering and traffic-related educational programmes at higher professional education and university levels. On the other hand, it also contains relevant information for professionals in the fields of traffic, transport and related areas, as well as for politicians and people from the media who require a certain degree of knowledge of road safety in the context of their work.

Because all relevant disciplines have contributed to it, the manual provides a balanced and structured picture of traffic practice in the Netherlands. However, a number of remarks should be made here. First of all, this manual discusses relatively ‘timeless knowledge’, such as models, methods and technology. Up-to-date information should be gathered from the internet. Moreover, to keep the manual manageable, its depth has been limited. This is solved in part by including bibliographical references and providing overviews of relevant websites and knowledge institutes. Finally, the manual is aimed specifically at road traffic and not at other transport systems
