Säkerhetseffekten av ökat cyklande: kartläggning av nuläget för att planera för framtiden


During the last decades, cycling has been highlighted as a travel mode with many positive qualities. The documents of Swedish national strategy reveal a trend of an increased cycling. At the same time, it is important that the safety of cyclists must be improved so that an increased cycling does not contribute to more injuries and fatalities in accidents. To cope with the increased cycling without compromising the safety, there is fore example, a need for better understanding of the relationship between the cycling flow and the injuries in various traffic environments.

In this project, three different studies were carried out to understand how the trend of cycling changes over time and how cyclists' injury risk is influenced by the cycling flow and the traffic environment. In the first study, a travel demand model has been developed that includes both mode choice and destination choice for cycling. In the second study, models for cyclists’ injury risks have been developed for different types of accidents and traffic environments. In the third study, interactions between different road users have been observed, to study how these are affected by the level of bicycle flow. Overall, the studies in this project have shown that bicycle flow is an important factor influencing cyclists’ accident risks. Higher bicycle flow corresponds to fewer interactions per cyclist and a lower risk of injury in a single bicycle accident as well as in a collision accident with motorised vehicles. We have also been able to demonstrate that it is possible to model travel choices and destination choice of cyclists and to develop models that describe cyclists’ injury risk. However, to provide better estimates, data with better quality are necessary for the model inputs, especially when it comes to the cycling and the description of cycling infrastructure.

Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.
