USING INTERACTIVE COMPUTER TECHNOLOGIES IN THE PROCESS OF VISUAL SPACE TRAFFIC SITUATIONS SIMULATION
Journal Title: Правовий часопис Донбасу - Year 2017, Vol 59, Issue 1
Abstract
The problem of modeling a traffic situation (a set of events developed on the road due to the interaction of the driver and other road users in certain spatial-temporal limits) with limited visibility from the perspective of different observers is regarded by scientists as during autotechnical expertise, and the organization of road traffic and evaluation of its safety. The possibility of flat graphic picture of traffic situation based on orthogonal drawings, axonometric or other specified metrically car image, road, roadside engineering, plantations and other objects is considered as part of the problem. The flat graphic pattern must be metrically determined, without limiting the angles of the operator of the vehicle reverse in orthogonal drawings that accurately conveys the value and value areas, corners and linear parameters of its elements, universal concerning different visibility requirements without requiring high skills and substantial costs in its creation. In addition, there should be given the possibility of automation by means of modern information technology processes of construction and reconstruction, and allowed to make quantitative and qualitative assessment survey properties of different models of cars at any stage of the analysis of traffic situations. To ensure the formation of flat geometric model elements, definition of numerical characteristics of visual space and analysis of different traffic situation models complex mathematical software solution to problems associated with the description of the functional relationship of visual elements and space of flat display, control the shape and position of of visual space objects, describing elements of the secondary model and its relationship with the original calculation of quantitative and qualitative characteristics of the simulated visual situation was used. Calculation of the quantitative and qualitative characteristics of the simulated visual situation was based on a spherical pattern, which is the base plane simulation visibility of vehicles. Subject area surrounding the operator in the functional areas of the system "man-vehicle" is included to the visual situation. These items include office management and structural elements of the vehicle contours of visual interference, the trajectory of the vehicle, the placement of surveillance, etc. The paper presents the visual space simulation algorithms of road situations with limited visibility to investigate different options of traffic situations, recreating conditions and terms of events and obtaining quantitative and qualitative characteristics of the simulated visual situation. The use of algorithms proposed for the use of interactive computer technologies will explore various options for a traffic situation recreate the situation and conditions of the event, and get quantitative and qualitative characteristics of visual simulated situation. The flexibility of the proposed algorithms will expand as necessary range of tasks and ensure their universality.
