Sažetak
Computer programs designed for traffic microsimulation have gained considerable popularity and widespread use, both in practical application as well as in research works. The number of traffic simulation models has increased significantly and until the end of the last century there were more then 50 simulation models available already. Their advantage is the ability to predict behaviour in everyday traffic, as well as in emergency situations. Unlike conventional analytical methods for traffic analysis, simulation models can also display the dynamics of traffic systems and 2D or 3D animations, as a result of their modeling, are much more understandable to incompetent population. The aim of this paper is to briefly describe the basic settings of microsimulation computer programs. The AIMSUN computer program will be described in details and the process of making the AIMSUN (Advanced Interactive Microscopic Simulator for Urban and Non-Urban Networks) microsimulation model for roundabout in Radnička Street in Rijeka will be shown. Since the traffic simulation computer programs are commonly used to estimate characteristics of traffic flow, such as the average travel time, the capacity of roads or the average speed of vehicles, models are based on adjusting the input parameters in order to reach a reasonable matching between model results and field data. This process is called calibration, and it is necessary in proving the authenticity of the simulation model and model validation. For the calibration and validation of the planned simulation model in this case, the obtained results were compared with those obtained by another analytical capacity method (Austrian method) and the SIDRA INTERSECTION (Signalised & Unsignalised Intersection Design and Research Aid) computer program which is based on the Australian calculation method for roundabout capacities.
