The use of simulation when designing road junctions

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.

El software de simulación como herramienta para el análisis de estructuras metálicas automotrices

“…Herramientas como ANSYS y SolidWorks se utilizan ampliamente para el modelado y el análisis de elementos finitos (FEA) a fin de evaluar la resistencia a los choques y la integridad estructural de los vehículos. Por ejemplo, ANSYS con su complemento LS-dyna se emplea para simular choques frontales y analizar la tensión y la deformación en carrocerías fabricadas con materiales como el aluminio y el acero, lo que ayuda a comprender la absorción de energía y la resistencia a los impactos durante las colisiones (Muhammad & Shanono, 2019;Terentyev et al, 2020). Del mismo modo, SolidWorks se utiliza para el modelado 3D de componentes automotrices, que luego se someten a análisis por elementos finitos para evaluar su rendimiento en diversas condiciones de carga (Arun et al, 2021;Choudhari et al, 2019).…”

Traffic Modeling of Intersections on Vajnorska Street in Bratislava

“…In such localities, there are schools, shops and services, hospitals, etc. Also, traffic modeling is a useful method to find a solution that would improve the current situation [12,13]. In this way, we can determine the impact of several possible solutions on traffic and compare them with each other.…”
