Electric simulation of urban road traffic flows

На основі виявлених аналогій в закономірностях перебігу процесів в електричних колах та міських автотранспортних потоків розглянуто (на прикладі міського кварталу) особливості електричного моделювання структурної конфігурації міської мережі та автотранспортних потоків. В середовищі NI Multisim зібрано електричну схему (модель) кварталу, на базі якої проведено електричне моделювання розподілу міських автотранспортних потоків на ділянках даного кварталу.The features of electrical simulation of the structural configuration of urban road network and transport flows have been considered based on the identified similarities in the patterns of process operation in electric circuits and city road traffic flows. Given the topology and an implemented plan of traffic organization on road sections of urban areas, using N1 Multisim a circuitry model of the quarter has been created, based on which an electric motor modeling of the distribution of urban streams in areas of the quarter has been conducted. However, simulations were carried out with different parameters of electric circuit sections. In particular, in the first case in the sections of a scheme the magnitude "normative" resistance was set; in the second case the value of an "actual" resistance was set. The "actual" resistance was calculated according to the real parameters of the actual carriage way sections of the urban quarter that allowed to create in the electrical model of the quarter the conditions of motor operation flows close to the real and accordingly - to conduct an adequate simulation of the distribution of road traffic flows in areas of the quarter. In addition, during the calculation of an "actual" resistance in the quarter sections the moving traffic lanes that are used for parking vehicles were taken into account
