The purpose of the roads on construction sites, also referred to as site roads, is to enable unobstructed internal transport and timely supply of both the construction site and construction process with materials. They connect storage areas, workshops and plants on the construction site with the place where works on the structure are performed. The quality of site road construction depends on the quantity, type and duration of the traffic they will need to withstand. When solving the issues of internal transport, it is important for the transport to be compatible with construction processes. Transport must be adapted to construction so that it conforms to the necessary dynamics of the construction process. It is possible to determine the trajectories of movement of construction machines and to analyse the swept path of vehicles through the planned routes by using computer programs for analysing horizontal paths of vehicles. The goal of the swept path analysis of construction vehicles is to maintain unobstructed work dynamics. Site roads are built in accordance with legal and technical regulatory requirements in order to enable unhindered internal transport for vehicles on construction sites and safety for people participating in the construction process, as well as to ensure visibility and to preserve the quality and quantity of transported materials needed to build the structure. This paper presents the particularities of designing and construction site roads and describes the process of analysing movement trajectories of the design vehicles on the selected construction sites by using computer programs Autopath 2017 and Autodesk Vehicle Tracking.
