Recent developments in the ITS field are orienting the research towards new paradigms or on the development of new traffic models based on existing ones. The main focus of this paper regards the development of a hybrid traffic model using existing models in the literature as a base, being able to support the modelling and control of automatic and connected vehicles. This paper proposes an innovative hybrid model tested in a close loop to verify its continuity and on an arc with a traffic light downstream to analyse the creation and discharge of queues. It also provides traffic indicators to compare these layouts modelled with the Hybrid model with respect to an application of a basic Cell Transmission Model and Cellular Automata model. Results provide three main contributions: i) the local consistency is verified; ii) it is suitable for applications of traffic control strategies; iii) it is reliable in terms of reality reproduction.
