The research leading to these results has received funding from the European Research Council under the European Union's Horizon 2020 Research and Innovation programme/ ERC Grant Agreement n. [833915], project TrafficFluid. ; Summarization: This paper presents the ongoing development of the microscopic TrafficFluid-Sim simulator, aimed primarily for Connected and Automated Vehicles (CAVs) under a novel lane-free traffic paradigm. In particular, TrafficFluid-Sim builds on the SUMO simulation infrastructure to model traffic environments featuring two novel vehicle characteristics: (i) Vehicles can be located at any arbitrary lateral position within the road boundaries; and (ii) Vehicles may exert, based on their automated driving and connectivity capabilities, "vehicle nudging" to other surrounding vehicles. As such, TrafficFluid-Sim enables simulation of novel CAV movement strategies for various types of road infrastructure and is an indispensable tool for the design, testing and evaluation of the characteristics of a future CAV traffic flow as an efficient artificial fluid, as envisaged by the ongoing TrafficFluid ERC project. ; Παρουσιάστηκε στο: 24th IEEE International Conference on Intelligent Transportation Systems

Conventional traffic management measures, currently applied, are valuable, but face limitations. During the last decades, a variety of vehicle automation and communication systems (VACS) have been developed and deployed, and many more are expected to appear in the near future. These systems provide a novel basis for a new generation of traffic management, which exploits emerging vehicle automation functions and connectivity channels to enable sensible traffic flow improvements in terms of efficiency and safety. A number of innovative concepts, tools and results that open up new horizons for traffic management research and practice in presence of VACS have been produced recently in the frame of TRAMAN21, an ERC Advanced Grant. This paper presents a collection of novel problems as well as of related traffic flow modelling, estimation and control developments for motorway traffic that can be used in the evolving traffic environment with VACS. ; Presented on: Annual Reviews in Control
