Need for an Integrated Modelling Approach for Mixed Traffic Flow Phenomena
Abstract: Traffic flow modelling can be in general categorised into three broad categories.Macroscopic models are generally based on aggregate level of traffic flow; whereasmicroscopic tools are more disaggregated and dynamic in nature. Benefiting from thesteadily increasing availability of affordable computing power, these more detailedmodels have become the tool of choice for operational studies, commonly in the form ofmicroscopic simulators. Among other dynamic models, mesoscopic ones are acompromise between the macro and …
