Urban mobility is usually provided through a transport infrastructure that includes all the elements that support mobility. On many occasions, the capacity of the elements of this infrastructure is lower than the actual demand and thus different transportation activities compete for their use. In this paper, we argue that scarce transport infrastructure elements should be assigned dynamically and in a prioritised manner to transport activities that have a higher utility from the point of view of society; for example, activities that produce less pollution and provide more value to society. In this paper, we define a general model for prioritizing the use of a particular type of transportation infrastructure element called time-unlimited elements, whose usage time is unknown a priori, and illustrate its dynamics through two use cases: vehicle-specific dynamic access restriction in city centres (i) based on the usage levels of available parking spaces and (ii) to assure sustained admissible air quality levels in the city centre. We carry out several experiments using the SUMO traffic simulation tool to evaluate our proposal.},

The concept of Smart Cities is a clear representation of this hype and provides a playground for novel approaches where the aim is to provide a high level of services to citizens in an optimized and thus, more efficient way. As a result of this research effort, many proposals have been and are suggested that could be deployed in the real world. However, such proposals also bring up multiple non-technical issues that need to be tackled before they can be actually implemented in practice.
