Driving speed is one of the most important factors in road safety and speed not only affects the severity of a crash, but is also related to the risk of being involved in a crash. Inappropriate speed is responsible for more than a third of all fatal accidents occurring on roads. In Poland every year about 70% of all traffic accidents occur in urban areas from which most is recorded at junctions. In order to improve traffic safety many efforts have been undertaken but their performance is still not satisfactory. One of the solutions for improving safety in cities is designing new and replacing already existing crossroads by roundabouts. They offer improved safety over other types of intersections having fewer conflict points, slower speeds and easier decision making. Specially single-lane roundabouts are pointed as an example of a very safe junction when compared to not-signalised and signalised. Author’s previous research considering traffic safety at crossroads in Bialystok, Poland has confirmed lower number of accidents and deaths at roundabouts when compared to other types of junctions but at the same time the number of collisions remained at unexpectedly high level. The aim of this paper is to analyse the influence of roundabouts on drivers’ behaviour and approach and exit speeds at roundabouts located in Bialystok, Poland. Measurements of instantaneous speed, acceleration, deceleration and route tracking data were undertaken to develop the investigation.
