Abstract

Road safety is an important issue for several sectors of society, and the speed practiced by drivers of motorized vehicles is a risk factor for both the occurrence and the severity of accidents. The objective of this research is to identify the influence of road and environmental factors in the choice of speed by drivers of passenger vehicles in urban intersections through the collection of naturalistic driving data. A total of 780 conversion maneuvers were analyzed in the city of Curitiba and its metropolitan region (Southern Brazil). The statistical analyzes showed that the highest speeds during the turning movement are practiced in left turns, without vertical deflections and without rain. The situations of speed variation were more significant at tighter angles of intersections, on secondary roads, without the presence of speed bumps and with higher approach speeds (entry speeds from 40 km/h). The naturalistic data showed to be adequate for the study of speeds in turning maneuvers.
