The presented information shows that in all selected emergency areas, the most common cause of accidents is speeding. A study of drivers' compliance with speed limits on the roads has showed that the vast majority of them does not comply with speed limits that operate in accordance with the requirements of Chapter 12 of the Traffic Rules of Ukraine and the requirements of prohibitory signs restricting speed. So, 100% of drivers have not followed a speed mode in the conditions of a dry covering. Setting speed limits only with road signs or legal requirements is ineffective. A comprehensive combination of structural elements of the road and means of traffic calming is necessary. The article presents the effectiveness of some traffic means calming on accident-prone sections of the highway M-06 Kyiv-Chop on the basis of world experience and the experience of some countries and Ukraine.","PeriodicalId":440945,"journal":{"name":"Automobile Roads and Road Construction","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117081687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of modern mathematical methods of implementation the comparative approach in real estate evaluation is analyzed in the work. Within this approach the following mathematical methods of determining corrective amendments to the value of the valuation object were analyzed: expert method, method based on solving a system of linear equations, calculation method based on normalized distances in the space of price-forming factors, and correlation-regression method. The main computing formulas and the sequence of calculations for each of the researched methods are outlined. The main criteria for choosing one or another method are defined on the basis of their advantages and disadvantages and application restrictions. The results of a computational experiment investigating the degree of sensitivity of mathematical methods regarding ways of formalization (digitization) of the initial qualitative information in determining the value of real estate objects within a comparative approach are presented. It is represented that the method of determining corrective amendments based on the solution of a system of linear equations is the most sensitive to the choice of the method of digitization of the initial data, the method of calculation based on normalized distances in the space of price-forming factors is less sensitive, and the correlation-regression method is not sensitive at all.","PeriodicalId":440945,"journal":{"name":"Automobile Roads and Road Construction","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128271757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydraulic calculation of bridges is one of the most important stages in determining its basic geometric parameters. Therefore, it should be based on the exact equations of hydraulics that characterize the behavior of water flow. Currently, the hydraulic calculation of a small bridge is based on an empirically established dependence, which is that the compressed depth under the bridge hc is associated with the support H approximate dependence hc ≈ 0,5H and is independent of the compression of the flow bridge crossing. In this work, it is theoretically proved that taking such a relationship between depths, you can get quite large inaccuracies in determining the depth in the compressed section hc, and hence in determining the speed in the calculated cross section of the bridgehead. Results. Based on the three basic laws of physics, namely: the law of conservation of mass (continuity equation), the law of conservation of energy (Bernoulli equation), the law of momentum (equation of the momentum change theorem), obtained an analytical relationship that establishes a relationship between compressed depth parameters hc and support H at different degrees of flow compression ε. Based on this dependence, an equation was obtained that establishes the relationship between the flow rate Q and the pressure in front of the bridge H. The obtained equation is similar in form to the flow equation through a wide-threshold spillway, with the difference that the flow coefficient m(ε) in the obtained equation depends on the degree of flow compression. Conclusions. The equation for determining the flow rate through the opening of a small bridge taking into account the flow compression is obtained. It is shown that the obtained equation coincides in form with the flow equation, which determines the flow through a wide-threshold spillway. The difference between these equations is that the flow coefficient m(ε) is a function of the flow compression coefficient ε. Using the boundary transition, it is obtained that m(ε) can vary from 1/3 √(2/3) to √0,5. Graphs are presented, which allow to analyze the change of hydraulic characteristics of the flow depending on the compression coefficient ε.","PeriodicalId":440945,"journal":{"name":"Automobile Roads and Road Construction","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124303259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every year, geodetic production faces new tasks that require a quick and correct solution. The modern level of automation of geodetic work is characterized by the widespread distribution of electronic total stations and satellite receivers, digital aerial photography complexes, field portable computers, as well as multifunctional software packages. This requires the use of new technologies and an automated information processing system, which includes the availability of a software complex for processing field measurement materials, means of automated data entry and graphical information, programs for processing graphics and automated drawing, devices for outputting graphic and textual information. The software for processing the received data of geodetic measurements should be such that the most complex tasks are performed, and at the same time it is easy to use. The development of software tools for processing geodetic measurements will help to reduce the time for camera data processing. The article evaluates the software in terms of the possibility of their practical implementation in the field of geodesy, as well as in terms of accessibility, comprehensibility and the presence of additional functions.
