Perception of three-dimensional geometric shapes as virtual 3D road markings

Excessive speed and poor driver perception are the causes of a large number of traffic accident. Analysis of the influence of geometry in driver behavior has been widely performed by different researchers. One way to improve road safety is to provide adequate visibility in order to help drivers adopt adequate behaviors. When budget and financial situation do not allow the implementation of expensive traffic solutions, some of them can be replaced by innovative, but simple solutions. In this study, the experiment was performed to explore how driver perception and behavior are influenced by two virtual 3D shapes projections - 3D alternative crosswalk pattern and speed bumps consisted from triangular prisms. The results show statistically significant differences between willingness to reduce vehicle speed as a response to the road marking using the square (rectangular prism) as the basis compared to one that has been used triangle (triangular prism).
