Adaptive Cooperative Control in Urban (sub) Systems
2013 - 2016
Urban systems like traffic, energy, and outdoor lighting are managed by self-contained embedded systems – though the managed processes are deeply interconnected. New applications and collective optimization require integration of these systems which represents a truly “systems of systems” integration problem: these urban systems evolve independently, have their own purpose and internal policies which must not be affected by such integration and have their own management. As a result, the integration has to manage emergent behavior and take non-availability of components as the norm rather than the exception. This is particularly challenging when control loop span across several systems. The project is aimed at developing an integration and coordination platform for urban systems to build applications across urban systems, provide adaptive and cooperative control for urban subsystems to optimize the combined performance, and provide general methodologies and tools for creating real-time collaborative applications for systems of systems.
Our role
We collaborated in development of the platform for the integration and coordination of urban systems (transportation, outdoor lighting, energy) to build applications across urban systems, to provide adaptive and cooperative control for urban subsystems, and to optimize the combined performance. We upgraded the traffic flow simulation framework, based on OpenDRIVE logical description of road network. The framework includes the descriptions of road network and traffic lights and allows the simulation of vehicle flows, according to the IDM (Intelligent driver model). It allows simple and intuitive planning of new and/or changed road segments, since their influence can be easily observed. The upgraded simulator also allows optimization of traffic lights’ switch segments, resulting in more fluent traffic flows.
