SP4 - SCOVA

The overall objective is to collect needs and requirements, to specify and to develop the safety application based on cooperative system implementing the active Safety Margin concept.
Moreover the sub-project will validate and evaluate those applications on the real test site reproducing the different use cases that will be available on the different driving contexts.
In particular, for this specific sub-project, the cooperative system channel will be mainly based on the V2V communication even if the information will be retrieved by the infrastructure system (SCOVA is mainly, but not exclusively, based on V2V cooperation).
The objectives, in terms of safety, are common to the COSSIB sub-project and referred to the local area in which the cooperative vehicles will run to:

• Increase the Safety Margin of vehicles using in-vehicle and infrastructure information;
• Improve, as an extension of autonomous intelligent vehicle, the range, the quality and the reliability of information;
• Create applications for Extended Cooperative Awareness by means of real-time reconstruction of the driving context and environment;
• Open the development of new safety applications based on cooperative approach;

The development will be characterized by a complete reconstruction of the driving context and road environment using in combination on-board sensors data and cooperative system information (vehicles net concept) in order to:

• Support drivers preventively to the proper maneuvers in the different contexts;
• Prevent the critical situation or manage them correctly;

The "dynamic vehicle net" and the minimal "vehicle to infrastructure net" extend the operative range of the actual on-board vehicle systems and allow the driver to receive the information on possible acceptable maneuver or to continue to maintain the same behavior avoiding the mentioned critical situation.

Hereafter the descriptions of some of the applications that will be developed in SCOVA subproject are reported:

• Road Intersection Safety. [more]

  Information to the driver and situation awareness at the intersections about blind spots and obstacles in a medium time-to-collision situation (1-10s before a critical event). The concept is that a driver will be informed in an early stage about possible threats, with special considerations taken to complex scenarios at intersections as well as information about vehicles appearing in blind spots due to obstructing structures and other vehicles.

• Lane Change Maneuvers in generic roads. [more]

  The vehicles are equipped with sensors measuring the road friction (sensors are available from a number of sources and will not be developed here). Vehicles following into the areas are informed about the presence of a black spot to be able to take appropriate actions. The context is generic roads, slippery conditions can cause severe accidents on straight highways, it does not need to be a curve to be dangerous; this is an especially important application for the Nordic countries.

• Frontal Collision Warning in generic roads. [more]

  The systems will be able to inform the driver in an early stage about potential risk of frontal collisions due for instance to the reduced speed of the preceding vehicles or. The SAFESPOT cooperative vehicles will communicate, directly to the other vehicles or to the SAFESPOT local infrastructure, their position and dynamics or the presence of obstacles on the road. The SAFESPOT information can be combined and processed together with the other on-board information about the obstacles, as available from possible sensors (e.g. radar or camera) in case preventive and active safety systems are already integrated in the vehicle configuration.

• Cooperative Vulnerable Road User Detection and accident avoidance in urban black spot. [more]

  A vehicle detecting a vulnerable road user (VRU, for example a pedestrian) informs the following vehicles about the presence of a VRU. This especially applies to known problematic spots like intersections and roundabouts.

• Road Condition Status Information. [more]

  The road condition is evaluated from the input of several sensors. The information is used to warn the driver and following vehicles of dangerous spots.

• Curve Warning in black spots. [more]

  The SAFESPOT system integrated in the vehicles will inform the driver about the risk of road departure and the driving safety margin, mainly in terms of speed to be maintained, according with the received information on the road geometry, surface status, traffic conditions etc.

• Predictive Speed Limitation and Safety Distance. [more]

  Thanks to the cooperative systems, the driver will be informed in advance about the driving safety margin in the black spots situations in front, such as the presence of static obstacles on the road or road works. Safety driving behaviours will be suggested (e.g. safety speed, lane to be occupied, trajectory etc.
