Abstract
In order to make effective plans of comprehensive traffic safety measures including the application of ITS technology, it is important to evaluate objectively the risk of traffic accidents for road sections. The microscopic data on vehicular movements required for the analysis are extracted from video data using the image processing technique. Especially, the objective indices to evaluate traffic conflicts are used for the analysis of the risk of vehicle collision at a weaving section. As an initial stage for developing a microscopic traffic simulation, this study analyzes the speed adjustment processes of the vehicles in the lane-changing situation.
