22.3 ROAD TRAFFIC SIMULATORS
Road trafc simulators also play a key role in the simulation of vehicular networks. In general, traf-
c simulators can be categorized as macroscopic and microscopic, depending on the level of details
describing the trafc ows [21]. Macroscopic models represent vehicles as an aggregated trafc
ow for simplicity. On the other hand, microscopic models have the ability to describe each vehicle
as an individual object with unique characteristics and so are able to account for the complex inter-
actions among vehicles and between drivers and transportation infrastructures.
Road trafc simulators require a complete set of inputs for reliable modeling of vehicula ...
