Simulations of different scenarios of the use of autonomous vehicles with a multi-agent model

Abstract

With technological advances and real-life trials taking place, the advent of autonomous vehicles (AVs) seems to be a matter of time. This raises many questions about the impacts that such a mode of transportation would have on mobility and its externalities. Using a multi-agent model, MATSim, this paper provides some answers to these questions by proposing three possible scenarios of use for autonomous vehicles that are simulated for the Montreal region:

• Private autonomous vehicles

• Robotaxis

• Shared robotaxis

Depending on the scenario, the introduction of AVs can engender a strong increase in travel distances due to empty driving. These additional kilometers lead to an increase in greenhouse gases, as well as an increase in congestion. Only one scenario, in which AVs are used as shared robotaxis, makes it possible to limit these effects.
