Understanding the relationship between perceived and objective bicyclist safety

We are facing a paradigm shift towards transport diversity. Cycling belongs to it. Safety is one main barrier to cycling, mostly related to the lack of proper infrastructures. For that, we need to rethink cities and build appropriate infrastructures to make cycling safer and more attractive. However, cycling infrastructures’ objective safety might not be perceived the same way by cyclists. If the infrastructure is not safe and cyclists think they are safe, they are at risk. By exploring the relationship between cyclists’ objective and subjective safety, the project will determine indicators that detect locations where they misperceive risk exposure. Ultimately, this research aims to propose cost-effective objective-safety interventions that can correct risk exposure’s subjective perception. Besides compiling potential corrective interventions, the research proposes a computer-assisted procedure for the respective Cost-Benefit Analysis to generate a cost-benefit ratio and rank them.
