INTERSECTION CONFLICTS

Commencing with the classical conflict diagrams for t-intersections, fourway intersections and multi-leg intersections, an exhaustive analysis of conflicts between two, three and four vehicles, with and without turning vehicles, is made. Conflict analysis is applied to the evaluation of priority rules, the effects of regulatory traffic control devices and accident analysis. For the latter risk rates are calculated for intersection flows in which turning vehicles are present. Conflict analysis is also applied to the dynamic situation i.e. When other vehicles not in conflict may nevertheless influence the way in which conflicts are resolved. The study of conflicts in the field is commented on, including observations of intransitive conflicts or conflicts that cannot be resolved by the direct application of priority rules.(a) /TRRL/
