The object of this study is the theoretical and methodological approaches to determining coefficient moisture conductivity subgrade soils. work focuses on considering European standards when devising a method for In course research, was developed soils K1, which characterizes diffusion movement water, through filtration K0, calculated in accordance with requirements based laboratory test data. proposed mathematical model built basis differential equation changes soil moisture. special that,...

Annotation: The study presents the results of research impact traffic intensity and flow composition on capacity highways bridge crossings based mathematical numerical modeling methods. main factors affecting have been identified. methodology for determining level approved by State Service Highways (now Restoration Agency) was adopted as calculation basis modeling. Also, calculations, updated statistical data, given in open literary sources, were used. 11 test options with different...

Summary The main aspects of methodological approaches to teaching mathematical disciplines with the aim forming fundamental professional competences future engineer are considered at article. study mathematics in a higher technical school is substantiated as necessary condition for formation an engineering type thinking. features and basic conditions effective competencies process training engineers considered, namely: using educational such methodical system mathematics, which would allow...

Optimal engineering solutions are not always available in the design of road pavement, resulting large losses construction. The justification optimal should be based on an analysis range natural conditions. An assessment technical and technological parameters determining work shallow drainage structures is carried out by means a collective expert questionnaires from leading experts sector. A target function has been defined for finding most under two groups criteria: estimated cost set...

The paper is devoted to the solution of nowadays relevant issue regarding scientific substantiation most effective methods mining rocks for various needs national economy, including construction highways. research was carried out on basis mathematical modeling methods, taking into account rheological properties rocks, heterogeneity their structure, microdamage and behavior rock massif over time. As part work, geological material consisting an isotropic viscoelastic matrix with stochastically...

To solve the applied problems of road and bridge construction, a method calculating effect damping flow wave height by vegetation on floodplains is given. achieve necessary extinguishing dangerous waves, parameters strip shrub plantings are substantiated. The proposed implemented in form engineering formulas for determining degree reduction wind waves during their passage through thickets floodplain areas open water flows zone influence crossings.

The paper examines the main indicators of road safety measurement based on European experience and countries world. It was determined that there are three allow for a qualitative assessment indicators, they indicative in case most reliable data number population, functioning vehicles accounting length roads traveled by these vehicles. An statistical deaths due to accidents made 2022 report V International Transport Forum. per 100,000 thousand population studied trend towards decrease...

The paper presents theoretical and methodological approaches to forecasting pricing in the real estate market based on study of stochastic models time series, which are statistical samples prices certain segments this generated consistently over time. main stages research series given. Two components distinguished - fundamental (regular) random (irregular). component contains trend, cyclical seasonal trends. is noise, slightly deviates value from trend. work analyzed price-forming factors...

The conducted researches aimed to analyze modern models and methods of implementation the comparative approach in property real estate appraisal, investigate evaluate their effectiveness, suggest ways further improving valuation. To achieve this aim, authors carried out a series computational experiments on computer. essence these was evaluation cost test properties based following methods: expert evaluation, solving systems linear algebraic equations, normalized distances space pricing...

До теперішнього часу практично не існує експериментальних досліджень дренажних споруд. Об'єктом представленого дослідження є дорожня конструкція з поперечним дренажем мілкого закладання, яка влаштовується на перезволожених ділянках автомобільних доріг. З метою визначення інтенсивності водовідведення дренажної конструкції, в залежності від властивостей матеріалів-наповнювачів, спеціальній моделюючій установці дорожньої конструкції проводився експеримент

. The effectiveness of modern mathematical methods implementation the comparative approach in real estate evaluation is analyzed work. Within this following determining corrective amendments to value valuation object were analyzed: expert method, method based on solving a system linear equations, calculation normalized distances space price-forming factors, and correlation-regression method. main computing formulas sequence calculations for each researched are outlined. criteria choosing one...

The paper investigates environmental risk factors that determine the value of real estate assets and make valuation decisions. It is determined components environment are object cumulative impact risk, indirectly through them objects people. Among all components, most decisive atmosphere, as harmful substances coming from atmospheric air into human body absorbed intensely. main criterion for assessment degree influence on health population. systematization factors, which provides an analysis...
