Abstract

In addition to four trained observers, video equipment and a traffic radar were used in the conflict measurements. The video equipment was used in collecting background data for traffic conflicts, traffic flows, the number of potential conflicts and vehicle speeds. The method was used in helsinki to study the effects of pedestrian refuges on traffic safety. In a before-after-study the number of conflicts observed on a street before the building of refuges were compared with the observations made after the building of refuges. On another street conflict observations at pedestrian crossings without refuges and a pedestrian crossing with a refuge were compared. In lahti the method was used in evaluating traffic safety at five junctions. The problem areas and spots of the junctions were located using the method. A number of measures to improve the traffic safety of the junctions were proposed based on traffic conflict observations.
