MODERN FOREIGN СAD FOR HIGHWAYS DESIGN

Abstract

Introduction. The analysis of modern processes of design automation shows that with the help of automation of engineering calculations and drawing works it is possible to significantly reduce the time of project development and improve the quality of design. At present, the design of roads is performed with the widespread use of automated procedures, ranging from the collection and processing of geodetic information and ending with the preparation of drawings and estimates. At present, the design of roads is mainly automated, with the help of computer-aided design systems. Computeraided design allows you to create a digital model of the road and all the necessary design documentation. Currently, fully computer-aided design used in Ukraine meet the standards for road design, as well as the requirements of specialists. Purpose. The aim of the article is to analyze the systems of automated design of transport facilities, as well as the analysis of the possibility of using foreign software products in Ukraine. The characteristics of software complexes are given in the work, the analysis of their functional possibilities is carried out and the basic features are revealed. Results. After the analysis of computer-aided design systems of transport constructions the basic principles of designing of highways are established. Almost all programs are based on generally accepted approaches to the design of longitudinal profiles, cross sections, design of transport interchanges and other elements of the highway. Conclusions. The analysis of software solutions in the field of computer-aided design of highways allows to highlight the main trends in road design. Today, modern computer-aided design no longer compete with each other, trying to provide users with the widest possible set of tools to solve almost all possible problems that arise in the design process. This is due to the fact that almost all systems currently have the necessary functionality to perform a wide range of design tasks. In one system some tools are a little more convenient, in another others. Therefore, the choice of appropriate computer-aided design sometimes turns into a subjective perception of the system, where an important role is played by a convenient and friendly interface of the system, ease of development, as well as thoughtful and logical technology.
