A Cyber-Physical System Modelling Framework for an Intelligent Urban Traffic System

Abstract

This paper presents a novel modelling framework for a component-based architecture that allows validating control strategies for urban traffic networks integrating intelligent traffic control based on cyber-physical transport systems, specifically using V2X (vehicle-to-vehicle) technology. The architecture named ITSiE (Integrated tools in a Simulated Environment), is constituted of three components that work in a cooperative way via a middleware, allowing to analyze the traffic behavior in a simulated environment for a defined urban area (selected network streets) and evaluate the impact of using intelligent transport strategies based in V2X. The first component named CiudadelaSIM executes the simulation and communicate in real time with the other components; the second component named SCPV (Road Proposal Capture System (by its meaning in Spanish), is used to define the simulated scenario (traffic lights, traffic policies, information objects) and the third component is a Control Speed System (SpeCo) which allow defining the intelligent strategy, through the capture of multiple techniques and methods to control the speed of the vehicles in a segment with particular features.
