CONFLICT STUDIES AT RURAL INTERSECTIONS

KONFLIKTSTUDIER I LANDSVAEGSKORSNINGAR. REDOVISNING AV TVAA PILOTSTUDIER

Accident analysis, the conventional method for studying the effects of measures for improved road safety, is very time consuming, and has deficiencies when it comes to describing the chain of events leading to the accident. The method described in this report, the conflict method, is based on the hypothesis that there is a connection between accidents and situations when accidents almost happen; here called conflicts. Conflicts are registered by observers, and tests show that the observers are able to identify serious conflicts in a reliable way after only four days of training. The method has been tested at 115 road intersections in urban areas, and a distinct connection between conflicts and accidents was detected in regard to two parameters: road user category and intersection traffic speed profile. The primary purpose of this report is to determine whether the method can be used to study intersections in rural areas with higher traffic speed. Two intersections with mean traffic speeds of 65 and 85 km/h were studied. The report gives a detailed account of the projects, and concludes that although much remains to be done concerning the development of methods to register conflict situations and to clarify the connection between conflicts and accidents, the method can be used to evaluate traffic safety measures in rural areas as well. /TRRL/
