Driving style is affected by development of cars and it has influence on the capacity of designed elements of roads and highways. Therefore, based on research, more accurate methods for assessing the capacity of road infrastructure are being developed. This paper presents the results of the research of weaving segments. It is focused on capacity assessment of these sections within the Czech Republic. Attention is focused especially on weaving segments in urban conditions with high traffic volume and on road sections with a speed limit less than 80 km per hour. Research verified the possibility of using these purposes by existing methodology developed for roads with a speed limit up to 80 km per hour.
