Resumen

Vehicle automation is not yet a reality which casts huge speculation of what will really happen when implemented in the near future. The effective deployment of such novelty, especially full automation, foresees potential impacts at different levels, the most direct ones being on the mobility level. Since the deployment of fully automated vehicles cannot be realized instantaneously in all areas of a city, a transitional phase must be assumed to mitigate the changes to come. It is critical to devise policies in order to implement such technology to leverage the benefits that it may bring. According to a literature review, deployment on urban networks revealed to be a gap in the literature. In order to address that gap, we want to support city planners by developing a strategy of integration for such technology into urban networks. At a traffic level, a strategy of dedicated zones for automated vehicles will be settled. We develop a model whereby the aim is to minimize the congestion problem through dedicated links where only automated vehicles can drive. A traffic assignment approach is used where the minimization of the sum of link travel times is part of the objective function. The number of automated vehicles is changed in function of a penetration rate. Each scenario is simulated and compared. This study begins the discussion of how to help public authorities plan the deployment of such automated vehicles and bring improvement to traffic in cities.
