Rome historical city centre is the laboratory of a successful experiment leading to consistent reductions of negative transport externalities via the implementation of a technologically sophisticated access control system. Access control embedded in the peculiar transport and mobility context characterising Rome forms the core of this paper. The origins and evolution patterns of access control in Rome are sketched, and the system's characteristics and main components are outlined along with implemented complementary measures. To conclude, research and development returns at the forefront with an overview of current activities to transform the automatic access control system successfully implemented in Rome into a road pricing system.
