Sažetak
Previous studies have shown that a valid roundabout design approach should include a determination of design elements based on the position of design vehicle’s movement trajectories obtained by swept path analysis in early project stages, and not a conduction of swept path analysis at the end of design process. Several software which enable such significant progress in the design practice (optimal design of roundabout elements based on the results of vehicle movement simulation) are currently available on the market. Consequently, it is of great importance to know their accuracy. The reliability of vehicle movement simulation results is usually verified by field tests in which the distances between the test vehicle’s movement trajectories are measured by means of a meter, which is a dilatory and time-consuming process. Within the scope of this study, a new approach for determination of the position of test vehicle’s movement trajectories at the test site using a precise GNSS (Global Navigation Satellite System) device is described. The test vehicle was conducting a critical manoeuvre (left turn for 270°) for ten times, and the distances between its movement trajectories were determined by means of a meter and a precise GNSS device. The situation on the test site was then simulated on a computer and the assessment of the accuracy of chosen software for vehicle movement simulation was made.
