Abstract

Traffic flow modelling can be in general categorised into three broad categories.
Macroscopic models are generally based on aggregate level of traffic flow; whereas
microscopic tools are more disaggregated and dynamic in nature. Benefiting from the
steadily increasing availability of affordable computing power, these more detailed
models have become the tool of choice for operational studies, commonly in the form of
microscopic simulators. Among other dynamic models, mesoscopic ones are a
compromise between the macro and micro levels. With the introduction of new
technologies, data of unprecedented quantity and ultimately quality, development of next
generation simulation models becomes an interesting research direction.This paper
proposes the need for next generation simulation models and presents a lead to
development of integrated models. The driver behaviour is a cause-reaction approach
involving several tasks within a short time interval. Hence an integrated system
comprising of driver decision making and the inter-dependence among the decisions and
anticipation capabilities better replicates the realistic diving behaviour. These integrated
models are driven by the distinct difference in driving behaviour, vehicle-type
characteristics, level of traffic etc. These kind of models are more apt particularly for
Indian mixed traffic conditions where the static and dynamic characteristics of the
vehicle vary widely.
