CVIS objectives

CVIS main objective is to establish (on the technical, technological and organizational level) wireless communication between vehicles and traffic infrastructure, thus improving traffic safety and efficiency. Other objectives are:

• to create a unified technical solution allowing all vehicles and infrastructure elements to communicate with each other in a continuous and transparent way using a variety of media and with enhanced localization;
• to enable a wide range of potential cooperative services to run on an open application framework in the vehicle and roadside equipment;
• to define and validate an open architecture and system concept for a number of cooperative system applications, and develop common core components to support cooperation models in real-life applications and services for drivers, operators, industry and other key stakeholders;
• to address issues such as user acceptance, data privacy and security, system openness and interoperability, risk and liability, public policy needs, cost/benefit and business models, and roll-out plans for implementation.

The communication

One of the core elements of the CVIS platform is a mobile router. The CVIS vehicle router provides a continuous Internet (IPv6) connection using the “best” available channel or network.

The software will continuously optimize the choice between mobile 2G/3G cellular, wireless LAN, short-range microwave (DSRC) or infra-red based on criteria such as signal strength, price, directivity, etc.

As position is critical for cooperative systems, the CVIS platform includes a hybrid location module combining GPS and innovative wireless positioning techniques that provides up to one meter accuracy.

CVIS implementation

The CVIS project is implementing example applications to prove the system concept and demonstrate the potential efficiency and safety benefits of cooperative systems.

Cooperative Urban Applications provide drivers with optimized speed and route recommendation based on more accurate detection of vehicles, hence of the traffic status on the road network, in order to reduce both delay and vehicle emissions. To improve traffic flow, dynamic bus lanes share spare capacity with non-priority vehicles.

Cooperative Inter-urban Applications deliver alerts and warnings directly from roadside equipment or traffic control center to an in-vehicle display. Typical information includes alerts for speed limits, weather, traffic jams, accidents or a wrong-way “ghost” driver.

Cooperative Freight and Fleet Applications provide safer and more efficient goods transport, such as access control to restricted areas and guidance on safe truck routes. Other innovations include optimized delivery logistics, truck rest area parking booking and dynamic loading-unloading bay reservation.

The Cooperative Monitoring Application provides harmonized traffic and network data collected from vehicles, roadside units and central services. The processed information is made easily accessible to other CVIS applications and road users, improving traffic safety, efficiency and convenience.
