Case Study: Road user behaviour in a complex intersection

During autumn 2017, Trafikverket (Swedish Transport Administration), Trivector and the City of Stockholm tested an experimental road design. The main objective was to increase the safety and mobility of cyclists. The experiment was performed at the busy and complex intersection between Kungsgatan and Sveavägen in central Stockholm. Viscando provided a detailed and objective study of road user behaviour through the experimental setup, and a detailed analysis of red light violations by vehicles and cyclists.

Road user behaviour
This is what Viscando’s measurements showed:

  • 27% of the cyclists used the experimental street design for turning left.
  • About 10% of the cyclists ‘jaybiked’ through the crossing, often taking ‘creative’ paths by combining the cycle path, pedestrian crossing and pavement.
  • About 3–5% of vehicles run a red light at the crossing.
  • About 20% of cyclists run a red light. With a right turn, the amount increases to 50%.
  • During the daytime about 20–30% of pedestrians walk against a red light. At night and in the early morning hours, this goes up to 60%.

“Viscando allows rapid evaluation of changes in the traffic environment. Instead of waiting for years to see the effect of a traffic safety improvement project, for example, we can instantly deliver objective information.” Amritpal Singh, CEO at Viscando AB.
