VehiLux model

The VehiLux model generates vehicular traces using freely accessible data sources, like open-source maps and real traffic counting data [1]. Parameters of the model were tuned by genetic algorithms (GAs) [2]. The model can be applied easily to any area for which map topology and basic traffic volume counting data exist. The overall architecture is presented in Fig. 1.

Generated traces consider:

aspects of vehicular traffic. Uneven distribution over a space is obtained by an original traffic demand model. It specifies individual origin-destination pairs (OD) in a process presented in Fig. 2.

A trace is additionally determined with a departure time that enables to reproduce the rush-hour peak in traffic demand. Traces are further assigned by a vehicle type that brings heterogeneity into microsimulation (e.g. acceleration and maximum speed capacities).
