Abstract
The high level of motorization in most countries of the world is the reason for the increase in the number of car accidents. Currently, it is understood that a further increase in the number of cars without significant changes in the transport infrastructure will only aggravate the already difficult situation on roads. The article addresses the issues of road traffic injuries and statistical information on road accidents. The analysis of the work of leading transport engineers presents the results of studies on the use of computer modeling tools for designing road conditions at various levels. From the presented analysis, it is possible to conclude that the most suitable tool for assessing the safety of road junctions is the PTV VISSIM software package, which also allows to export vehicle trajectories to SSAM software. In the framework of the analytic survey of the intersection safety, based on the analysis of vehicle trajectories, the parameters of the future conflict of the planned road junctions were established. Studies have shown that a road junction at different levels makes possible to triple the safety of junctions in comparison with the roundabout. The use of simulation allows not to wait for emergency cases, but to evaluate hypothetical structures and alternative layout options for road junctions, where it is not possible to use traditional, statistical models for assessing the probability of car accidents.

Road transport is an important economic tool significantly effecting the pace of socioeconomic growth of the society as a whole
An analysis of the work of the world's leading transport engineers showed that at the moment there are a large number of software products designed to simulate traffic situations at various levels
The considered computer modeling tools are distinguished by functional capabilities and the degree of complexity of the transport tasks being solved
Summary
Road transport is an important economic tool significantly effecting the pace of socioeconomic growth of the society as a whole. The high growth rate of the fleet of cars, in addition to economic reasons, is due to the high level of comfort in the operation of automobiles, which allows for the transportation of passengers and goods in the optimal time and on the shortest route. It is obvious that the intensive growth of the fleet of motor vehicles in most countries of the world has led to a number of negative consequences. A prominent increase of the ratio of vehicles to population has led to a decrease in the operation efficiency of street and road networks [3]. It should be noted that reducing road safety (an increase in the number of emergencies and the number of conflict points) is an urgent problem when a high level of motorization [4]
