Background & Policy context

A 'federative' action, conceived under the Predit 2 programme, ARCOS brought together some 60 partners in a global approach regarding the vehicle-driver-infrastructure system, in order to contribute to improved road safety.

ARCOS aimed to validate concepts and feasibility to achieve four functions:

  • to regulate inter-vehicle distances,
  • to prevent collisions with fixed, stopped or slow-moving obstacles,
  • to prevent vehicles straying from the lane and 
  • to alert upstream vehicles of accidents or incidents.

Three types results were expected:

  • Knowledge (particularly on the development of human-machine interfaces);
  • Technologies, tools and methods (prototypes of sensors, methods of perceiving the environment, methods of treating information);
  • Experimental prototypes, enriched by co-operation across multi-disciplinary fields.

This public-private collaboration effort should bring about a community of businesses and laboratories capable of collectively assuming responsibility for advancing discussions and technical challenges related to the deployment of road safety objectives. Some examples of developments are:

  • Obstacle detection sensors;
  • Estimation of mobile adherence;
  • Lateral drifting sensors; 
  • Inter-vehicle communication vectors.

In addition, individual acceptance criteria, studies of responsibility-transfer, economic studies for public authorities, etc.


Functional analysis applied to the four safety functions resulted in 11 broad structuring themes:

  1. Perception of environment before the vehicle;
  2. Other measurement techniques: visibility and adherence;
  3. Data processing and command development;
  4. Transmission and communication;
  5. Simulation / evaluation; accidentology;
  6. Man-machine system;
  7. Individual and social acceptability;
  8. Other collective social and technical aspects;
  9. Experimental means;
  10. Functions management / ARCOS technical assistance;
  11. Development of alarms for trucks in potentially dangerous situations.  

Three experimental campaigns were planned in the course of the project.
