  • Experimental and theoretical study of physical and chemical transformations of woody biomass in the production technology of fibreboard

    In accordance with the theory of mathematical and statistical modeling, evaluation studies, selected the main characteristics of the models describing the studied production process of fiberboard using different types of binders. In accordance with the developed plan of the selected controlled studies, uncontrolled and controlled factors of the process under study. The levels, steps, and intervals of variation of the studied factors. As a method of obtaining the mathematical dependencies of the quality indicators of fibreboard from the kind of used binder was enacted active single-factor experiment. The results of the studies conducted statistical analysis of the dependence of physical-mechanical characteristics of the performance of the finished plate thickness fibreboard manufactured by wet and dry methods, interpretation of research results, quantitative and qualitative relationships between the studied parameters.

    Keywords: strength, water absorption resin, fiberboard, thickness, experiment planning, mathematical model

  • Estimate travel time based on the simulation of traffic flows

    To solve the traffic problems , namely the coordination of the movement of transport modes have been developed micro-and macro-modeling programs that predict traffic situations , to choose the most appropriate solutions for specific problems by using real data and statistics. The emergence of intelligent transportation systems, traffic simulation pushed to the fact that it has become one of the most used methods for studying the traffic flow, allowing to plan and predict the situation on the roads. The possibilities offered by the modeling of traffic flows , helping to simulate the situation on the roads, and it becomes a unique tool for understanding the complexity of transport systems. For precise work of model needs an indicator such as the time of the trip. Travel time - the time it takes to travel from one point to another , consisting of travel time and the stop time of the vehicle.

    Keywords: travel Time, microsimulations , flows, methods of intelligent transport systems

  • Research of the influence of the development level of intelligent transport network on the efficiency of intermittent bus lane priority application

    The article deals with the analysis of intermittent lanes priority based on simulation. The implementation of intermittent lanes priority system is only possible within the framework of urban intelligent transportation system (ITS).  In some cases, there are not always enough ITS components for the operation of intermittent lanes priority system. Based on the simulation it is possible to determine the efficiency of the intermittent lanes priority system with the minimum or complete number ITS components. To compare the effectiveness of intermittent lanes priority system the simulation was performed for the four scenarios:
    1. Without the use of public transport priority
    2.  Classically  marked priority lane
    3. Using the intermittent lanes priority system with a minimum number of ITS components
    4. Using the intermittent lanes priority system with the full amount of ITS components 
    According the results of simulation we concluded that the minimal intermittent lanes priority system is noticeably inferior to a fully functional intermittent lanes priority system on the effectiveness, but such system does not require a high level of development of the urban ITS and can be considered as the first stage of a complete intermittent lanes priority system.

  • Methods of estimating the adequacy of simulation results

    This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation

  • Modeling and analysis of the demand for new transport network improving objects

    When introducing a new facility to improve the transport network, there are appear many risks. The priority is the financial riskbecause core funding for these projects comes from private organizations. Careful calculation of demand is an integral part of the development project. For the effective analysis of the transport network since the project requires a conscientious approach to the latest technology.
