Cooperative systems are systems by which a vehicle communicates wirelessly with another vehicle or with the roadside infrastructure, like intersections, with the ultimate aim of achieving benefits for many areas of traffic management and road safety.
Intersections could be fitted with sensors (radar, cameras, RFID readers) that would locate the whereabouts of cyclists and wirelessly transmit this information to the relevant vehicles. Such information could also be gathered from vehicles and transmitted to the infrastructure or other vehicles for analysis purposes. Cooperation means shared perception, decision-making and action planning between several vehicles and traffic infrastructures (e.g., traffic light control) and increased awareness of crash risks between road users on intersections.
The overall architecture of the system will include: a detection system, a situation assessment system and a communication gateway that can interact efficiently through different technologies with the given in-vehicle systems and roadside signalling. The heart of the cooperative platform that will be used is the application of communication standards for the real-time exchange of information between vehicles and roadside systems.
In the demonstration phase, XCYCLE will use a stationary and a mobile demonstrator.
The “Stationary demonstrator” will be placed in Braunschweig, Germany at AIM (Application Platform for Intelligent Mobility) test bed (at an intersection). The test site AIM is a new large-scale research infrastructure. An entire city serves as a platform for application-focused science, research, and development in the field of intelligent mobility services.
The “Mobile demonstrator” is based on two quasi-stationary poles with a respective sensor head (setting equals the stationary version). One of the poles incorporates an additional RSU-unit for communication with the traffic participants; the poles both incorporate an outdoor cabinet for the computer hardware.
