Hybrid driver-vehicle dynamics in microscopic modeling of traffic networks*

In this paper the microscopic traffic modeling framework proposed by the authors is enriched with a hybrid driver-vehicle model. The proposed framework models traffic networks exploring vehicle to vehicle and road to vehicle interactions. Vehicles are modeled as agents composed of simple vehicular dynamics controlled by a hybrid automaton representing the control that each driver applies to his vehicle to steer its dynamics. The continuous dynamics of the hybrid system implements a speed-position tracking control. The discrete event dynamics set the objective of the control according to the driving task chosen by the driver on the basis of the perceived environmental information.
