A dynamic wake avoidance system utilizes aircraft and atmospheric parameters readily available in flight to model and predict airborne wake vortices in real time. A novel combination of algorithms allows for a relatively simple yet robust wake model to be constructed based on information extracted from a broadcast. The system predicts the location and movement of the wake based on the nominal wake model and correspondingly performs an uncertainty analysis on the wake model to determine a wake hazard zone (no fly zone), which comprises a plurality of “wake planes,” each moving independently from another. The system selectively adjusts dimensions of each wake plane to minimize spatial and temporal uncertainty, thereby ensuring that the actual wake is within the wake hazard zone. The predicted wake hazard zone is communicated in real time directly to a user via a realistic visual representation. In an example, the wake hazard zone is visualized on a 3-D flight deck display to enable a pilot to visualize or “see” a neighboring aircraft as well as its wake. The system substantially enhances the pilot's situational awareness and allows for a further safe decrease in spacing, which could alleviate airport and airspace congestion.

A vehicle platooning control system is a vehicle platooning control system that controls a relative relationship between vehicles so that a plurality of vehicles runs in a row. In this system, each target value of a relative relationship between vehicles continuous in the longitudinal direction of a row is determined on the basis of a relative relationship error propagation ratio which is a ratio of an error of the relative relationship propagated to the rear vehicles running in the row.

A dynamic road marking system for influencing a flow of traffic has a plurality of road marking units (3, 3′, 3″, . . . ) provided with a light source emitting light in the direction of a driver of a vehicle (6, 6′) traveling over a roadway (10). The road marking unit includes detection apparatus (2) for detecting the intensity of the flow of traffic, and conversion apparatus for converting the detected traffic intensity to a desired traffic intensity with a desired mutual distance between the vehicles (6, 6′) and / or a desired velocity of the vehicles (6, 6′). The road marking system generates a guidance light (1, 1′, . . . ) which seemingly moves along with the flow of traffic by suitably switching on and off the light source in the road marking units (3, 3′, 3″, . . . ). The flow of traffic moves along with the moving guidance light (1, 1′, . . . ). The speed of the guidance light (1, 1′, . . . ) is adapted to the desired mutual distance between the vehicles (6, 6′) and / or to the desired velocity of the vehicles (6, 6′). Preferably, guidance lights (1, 1′, . . . ) are disposed between each of the vehicles. The dynamic road marking system enables higher traffic intensities on roadways and improved traffic safety. In addition, the road marking system including guidance lights (1, 1′, . . . ) facilitates interweaving of vehicles.
