Introduction to iTETRIS
The most important question raised today by road authorities is: how can the actual worth of investment and effectiveness of traffic engineering applications on city road traffic be estimated? V2V/V2I communication technologies promise to improve traffic management through Real-Time exchange of Traffic Information (RTTI). However, before cooperative ITS systems are widely deployed and evaluated in Field Operational Tests (FOTs), road authorities need clear evidence at city level of the benefits and impact of these solutions for their own particular scenarios.
The iTETRIS project has set out to satisfy this need through the development of an open, ETSI standard, compliant, and flexible simulation platform that will create close collaboration between engineering companies, road authorities, and communications experts. iTETRIS integrates wireless communications and road traffic simulation platforms in an environment that is easily tailored to specific situations allowing performance analysis of cooperative ITS at city level. The accuracy and scale of the simulations leveraged by iTETRIS will clearly reveal the impact of traffic engineering on city road traffic efficiency, operational strategy, and communications interoperability.
