Abstract: The issue of using safety islands as an additional tool for influencing the level of accidents involving pedestrians has studied. A new type of modern security island - a modular island - is proposed, and the calculation of the maximum strength of the anchor fasteners of the arrangement is proposed. The proven fact is the effectiveness of the use of so-called "safety islands" on roads - an engineering device that allows pedestrians to safely cross the too wide carriageway of roads and technically narrow the traffic lane. Ensuring a high degree of protection of pedestrians stopped at the safety island from being by a vehicle remains an urgent issue. The search for a mathematical expression of the dependence of the holding capacity of the elements of the safety island on the strength factor of the material and the dimensions of the parts used is of interest from both a theoretical and a practical point of view. The presence of such a dependence would make it quite simple to determine the effect of changes in the cross-section of the fastening elements on the value of the energy intensity of the structures. Ensuring a high degree of protection of pedestrians stopped at the safety island from hit by vehicles remains an urgent issue. The search for a mathematical expression of the dependence of the holding capacity of the elements of the safety island on the strength factor of the material and the dimensions of the parts used is of interest from both a theoretical and a practical point of view. The main task in the search for mathematical dependencies was the modernization of already known structures and the determination of their maximum capabilities without changing the kinematics of the structure when interacting with road transport. In order to determine the possibility of increasing the holding capacity of the safety island fastening elements based on, it is necessary to consider different stages of the construction when cars hit them. The method of calculation proved that modular safety islands have a number of advantages compared to traditional ones, which will be fair if the necessary deterrent ability and strength factor of the material of the fastening elements ensured.
