Road design for senior drivers and pedestrians

Due to the ageing of the population and the increasingly larger demands for elderly mobility our profession is facing new issues and requirements. In the future, more attention will have to be paid to the problems and needs of the elderly, as they will constitute a large part of the society. Cognitive, visual and psycho-motor deficiencies of senior drivers which accompany age-related changes, diseases and are often aggravated by drugs were studied in the thesis with the aim to prolong elderly mobility. Because of these changes, senior drivers experience difficulties in merging into traffic, decreased situation awareness, slower reaction times in traffic situations and difficulties in operating the vehicle.\ud In the second part of the thesis, possible solutions from various countries for adapting the road infrastructure to the needs of senior drivers and pedestrians were presented. By adjusting the geometric elements of intersections, building left- and right-turning lanes, improving horizontal and vertical traffic signs as well as traffic lights, replacing traditional intersections with single-lane roundabouts, using advance signals, additional warnings and other improvements it is possible to facilitate elderly mobility and improve their traffic safety. \ud In the practical part of the thesis, we presented a critical evaluation of the existing dangerous section Dolenja Trebuša–Želin and the intersection Dolgi most with the highway access point Ljubljana-west. Based on this, a road design with suggested improvements for senior drivers\ud and pedestrians was developed
