Level of organisation of transport flow influences on a day-to-day life of people from modern megapolises. Around 70% of citizens of modern megapolises spend more than two hours a day on the road. Many road networks are overloaded and as a result in the rush hour there are long traffic jams and if the weather is bad, then a situation on the roads gets catastrophic.
Typically this problem is solved by reorganization of transport flows or by modernization of road interchanges. Both variants do not solve the problem without painstaking preliminary analysis. Modelling of proposed solvings of the problem makes possible to prevent from mistakes in calculations and to analyze different scenarios of sequence of events.
It is possible to make models as macrosystems (squares, districts), as microsystems (road interchanges, crossroads). Ended model represents a graphical representation of simulated system, at which there are different input parameters (density of flows by directions, consist of flows) and it makes possible to receive statistic data of chosen scenario (for example, graphs with values of throughputs of road interchanges) and to import results in external files.
Moreover on basis of the ended model of transport system it is possible to conduct optimization experiments, – comparison experiments for different scenarios of the model.
Simulation modelling helps prevent from unnecessary expenses coming from mistakes made in the process of designing roads.
