Cyklisters hastigheter: Kartläggning, mätningar och observation

Many different road users share space on pedestrian and cycle paths, and their speeds may differ greatly. Differences in speed can complicate the interactions between road users which in turn may cause incidents and accidents. The purpose of this project is to enhance the understanding of cycle speeds on the pedestrian and cycle paths and to understand how the cyclists adapt their speed to other road users and to the surrounding environment. Three different data collection methods were used: Previous measurements of cycle speed and flow in three different municipalities, Eskilstuna, Linköping and Stockholm (18 locations); new measurements in Linköping (4 locations) and Stockholm (1 location); and new observation studies of bicycle types at these locations.

The average speed of cyclists on the paths selected varies between 15–25 kilometer per hour. As expected, the lower average speeds were found in the uphill directions, near intersections and in paths with high pedestrian flow. The higher speeds were found in downhill directions and on commuter routes. No general increase in cyclists’ speed was found between years, neither in mean speed nor in proportion of high-speed cyclists. However, bicycle flow has increased in many of the locations over the years. This implies that the number of cyclists holding a high speed, above 30 kilometer per hour, will be increased, even if the proportion of high-speed cyclists stays the same. This may mistakenly be interpreted as increased mean speed. About 70–95 percent of the road users observed on the pedestrian and cycling paths were cyclists and roughly 5–30 percent were pedestrians. An extremely small proportion were mopeds, 0.2 percent. The comfort bike was the most common type, followed by the trekking bike. The electric and racer bike occurred in all locations, but varied 1–10 percent respectively 1–15 percent. The relationship between the type of bike and the speed claim is not entirely clear, but cyclists on the electrical and racer bikes generally have higher speed claims.
