Public ISBD Titre : Roadside safety : a knowledge-based system for alternative configuration of fixed roadside objects Type de document : texte imprimé Auteurs : A. Ramache, Auteur ; M. G. H. Bell, Directeur de thèse Editeur : University of Newcastle Upon Tyne Année de publication : 1991 Importance : 177 f. Présentation : ill. Format : 27 cm. Note générale : Thèse de Doctorat : Génie Civil : Royaume-Uni, University of Newcastle Upon Tyne : 1991 Bibliogr. f. 178 - 192 . Annexe f. 193 - 227 Langues : Anglais (eng) Mots-clés : Roadside  safety  improvements ROSDIS Vehicle  roadside  accidents Index. décimale : D001091 Résumé : Every time vehicles leave the road they are likely to collide with fixed roadside objects, such as lighting columns, signposts, etc. Traffic and highway engineers have always been faced with the difficult task of making important decisions regarding the selection and implementation of roadside safety improvements. To facilitate their decisions, a knowledge-based system called ROSDIS (ROadside Safety Design and Improvement System) has been developed. This thesis describes the knowledge-based system which constitutes a significant extension of an existing model and uses system safety methodology. A fault tree depicting the process behind any single vehicle roadside accident has been implemented in a prototype program written in Prolog, which has since been refined. Since the most important part of the fault tree lies in the determination of the probabilities of basic underlying events, consideration was given to how they can be related to available and measurable data. An analysis of single vehicle roadside accidents was carried out. The objective here is to extract information from the available data, so it can be utilised by the system. Accident records do not provide all necessary information on the engineering aspect of single vehicle roadside accidents. This lack of information led to the design and implementation of a field procedure to collect the missing data manually. The system enables the user to experiment with different configurations of fixed roadside objects and select the configuration which minimises the probability of collision. The explanation facility of the system allows the user to see why a question is asked by the system and how the probability of collidion was reached. The result of this research should eventually be a quantitative design tool through which a risk situation at the roadside can be assessed and safety decisions made concerning the locations and types of roadside objects.
