COOPERATIVE URBAN APPLICATIONS

The CURB Sub-project is one of the three application projects of CVIS.

It will develop and validate cooperative service components to improve the efficient use of the urban road network; there are positive effects on traffic safety and the environment as well. Main innovation will be the cooperative exchange of data between individual vehicles and the roadside equipment, and provision of dedicated, targeted services to individual vehicles from the roadside. This will create a cooperative system for detailed travel data collection, personalised travel information, greatly improved management of traffic at all urban levels and promote the efficient use of road space.

CURB will develop concepts and a toolkit for vehicle-infrastructure cooperation suitable for urban roads, within the high-level CVIS architecture. This will enable advanced traffic optimization scenarios, effective throughout the network, at the same time maintaining a high level of local response to momentary traffic fluctuations, disturbances and priority vehicle requests.

Four useful and realistic example applications will be developed, implemented and tested in parallel, for three fundamentally different (system) levels. However they are ultimately part of the same management process and contribute to the same efficiency objective.

Cooperative Network Management

Optimum area traffic management by using vehicle/driver destination and other characteristics, and individualised route guidance.

Cooperative Area Routing

Intersection controllers signal momentary disturbances in traffic flow in their area of control, and give individual, destination-based and appropriate rerouting advice to approaching vehicles.

Cooperative Local Traffic Control

Enhanced local intersection traffic control that cooperates with the approaching vehicles, gives control and traffic state related information to the driver and supports and creates green waves through speed recommendations (profiles) for the drivers and data exchange with neighbouring intersections.

Cooperative Flexible Lane Allocation

To increase the capacity of the road infrastructure, a dedicated bus lane is made available to “licensed” and CVIS-equipped vehicles, travelling in the same direction, allowing them to use the lane when and where it would not be a nuisance to public transport and the arguments of speed, punctuality and economy would not be compromised.
