Abstract | ||
The issue of transportation is of primary importance in our
societies. A large share of greenhouse gases is generated by the
transport sector, and road casualties are one among the most common
causes of death. In the present work, we study commuter choice between
alternative transport modes using an evolutionary- game model, wherein
commuters can choose between using their private car or taking the
bus. We examine the possible dynamics that can emerge in a homogeneous
urban population, where agents are boundedly rational and imitate the
others. We obtain a different number of equilibria depending on the
values of the parameters of the model. We carry out comparative-static
exercises and examine possible policy measures that can be implemented
in order to modify the agents’ payoff, and consequently the equilibria
of the system, leading the society towards more sustainable
transportation patterns.
