Abstract

The increasing complexity of modelled systems opens up questions of combining several modelling approaches in order to achieve higher efficiency and the required clarity of the simulations performed. For this reason, in addition to standard application-oriented modelling tools, we can see the growing popularity of the so-called hybrid or multimethod modelling approaches. A typical representative of such a modelling environment is the AnyLogic general-purpose modelling tool. This article describes the authors' experience with this tool in solving a selected problem in the field of modelling transport processes in urban areas. Using the example of the uncontrolled selected intersection, the procedure of creating a model with a more detailed analysis of its selected parts is discussed. The model based on real conditions is elaborated and compared with the model containing the fictitious traffic light control. Comparison is based on measuring the time that vehicles moving in the critical direction spend in the model. Both discussed models are stored in the cloud and may be run and study free.

Highlights

Computers allow researchers to simulate how different types of devices or processes work
In order to summarize the implemented steps, we briefly describe a sequence of individual modelling actions, some of which supplemented by comments and described in more details
cumulative distribution function (CDF) is displayed as a polyline on top of probability distribution function (PDF), and the mean value as a black vertical line placed at the corresponding x-axis value position [26]

Summary

Introduction

Computers allow researchers to simulate how different types of devices or processes work. To make this possible, a set of assumptions are to be defined in the form of logical or mathematical relationships that make up the model. Models being simple enough make possible to apply analytical (mathematical) approaches; most real-world systems are too complex and may be studied by means of simulation only. The domain of road transportation and traffic operation is not an exception. For a comprehensive and state-of-the-art treatment of all the important aspects of a simulation study, see [1]. A comprehensive, in-depth, and state-of-the-art summary of the important aspects of transportation analysis and modelling and simulation is provided in [2]
