The Dynamic Approach to Evaluation of Visual Road Image
 
The motor road visual quality, which includes such basic categories, as visual clearness and fluency, in conformity with earlier investigations, has an essential significance in the driver’s information perception. The managerial decision taken by the driver depends on its result and, hence, on the traffic safety, too. To secure the road visual depiction, adequate to the situation, it is necessary to perform a visual analysis the designed motor road alignment. Up to now, the described road visual analysis methods have been based on evaluating the static perspective image elements, which do not correspond to the real perception process in case of a car driving. This work describes the opportunity of the dynamic, corresponding to real perception circumstances, visual quality evaluation. The method anticipates the image line evaluation according to the visual fluency criterion, when the image changes corresponding to the observation point location, in the real car movement case. The method is checked by the optimization solution example following the visual quality criterion corresponding to the given road parameters.
 
Keywords: road alignment, road visual quality, car-driving process, image analysis, dynamic image perception.
