"Road operators, infrastructure providers, fleet operators and their drivers as well as other road users will cooperate to achieve the most efficient, safe, secure and comfortable journey. Vehicle to vehicle and vehicle to infrastructure cooperative systems will contribute to these objectives and go beyond the improvements possible with stand-alone systems" (definition of cooperative systems given by the European Commission)


Cooperative Intelligent Transport Systems (C-ITS) is an ever-growing field within the transport sector. C-ITS systems allow vehicles to communicate with other vehicles, other road users and with the road infrastructure. C-ITS services advise drivers on how to act within specific situations to optimise mobility for both people and goods.

Compass4D services 

Compass4D focused on three services which will increase drivers' safety and comfort by reducing the number and severity of road accidents, as well as by optimising the vehicle speed at intersections and by possibly avoiding queues and traffic jams. The three services are: the Energy Efficient Intersection (EEI), the Road Hazard Warning (RHW) and the Red Light Violation Warning (RLVW). Compass4D services have also a positive impact on the local environment by enabling the reduction of CO2 emissions and fuel consumption for equipped vehicles.


As the focus of Compass4D is on actual deployment, these services have been implemented through a combination of established technologies and available pre-commercial equipment. Dedicated short-range communication (ITS-G5) and cellular networks (3G/LTE) have been used, following ETSI TC ITS standards. In addition, Compass4D has identified solutions to deployment barriers and elaborated business models to make the services self-sustainable for a wide commercialisation. This work includes cooperation with standardisation organisations and global partners to achieve interoperability and harmonisation of services.


The Compass4D services have been piloted during one year in seven cities: Bordeaux, Copenhagen, Helmond, Newcastle, Thessaloniki, Verona and Vigo. Prior to the pilot operations, the implementation phase lasted more than one year and was a result of teamwork involving all consortium partners. Overall, during the three years of the project duration, Compass4D has installed equipment and implemented cooperative services on almost 300 road side units and traffic lights and on more than 600 vehicles, with over 1200 drivers involved in the pilot operation.


In October 2015, the Compass4D partners decided to continue operating the C-ITS services in 2016, that is to say beyond the EU funded project life and for at least one year, with the goal of moving from pilot to large scale deployment to ultimately paving the way towards a self-sustained market.
