In the last few years, an increasing amount of research has been dealing with the development of autonomous vehicles (AVs). With the increasing deployment of the AVs on the roads over the years it is necessary to adapt road infrastructure to accommodate them. This paper gives an insight into the impact of AVs on the road infrastructure such as horizontal and vertical alignment, and dimensions of cross section elements. The implementation of the AVs into the road network will not depend just on the preparation of road infrastructure but also on the future development of vehicle automation and the proportion of AVs according to conventional vehicles (CVs) into the vehicle fleet. Therefore, according to AVs proportion into the fleet, three different scenarios for road infrastructure upgrades are given. Finally, the advantages and disadvantages of the introduction of AVs regarding the requirements for existing and future road infrastructure are discussed.
