Analysis of the accuracy of different geodesic measurements methods for measuring roads

Abstract

Roads, railroads and streets are one of the most important infrastructure, so it is very important rightly construct and to make control geodesic pictures of them. In order to qualitatively and effectively carry out the following operations, it is necessary to assess the methods (advantages and disadvantages) used for these works. The work describes the usage of the measureaments devices, their specifications, data analysis and comparision with the most eficient device. Railway tracks require more thorough maintenance and analysis than regular roads for cars. Defects are here noticed and recorded by using special equipment. Construction of railway roads and their exploitation requires optimal accuracy and monitoring of surveying. It is related to maximum allowed speed of trains, the environment, transport and human safety. Their monitoring needs to be improved by applying geodetic devices for surveying. Comparing analogous surveying conducted using EM140 machine with that of geodetic equipment, one can see the advantage of geodetic surveying. Technical gaps in the surveying process, data storage and procession were evaluated as well. It was discovered that maintenance and monitoring works should be pursued more frequently using high accuracy geodetic equipment. The main aim of this article is to evaluate differences of the technological process and control technology by conducting geodetic investigation in railway objects.
