Flow corridor detection and display system

A vehicle driving aid system comprising:

• sensors configured to measure a space in front of a vehicle;
• a module having trajectory data predictive of vehicle trajectories via a memory defining vehicle dimension data, a dynamic memory including behavior and skill data, and a processor to combine the space with the trajectory data to detect a corridor, and quantify a risk level associated with the corridor, wherein the module is configured to, in response to the sensors detecting that a proximity to neighboring vehicles has fallen below a predetermined threshold, automatically detect the corridor and quantify the risk level;
• and
• a display to represent the corridor and risk level as a series of nested gates showing a recommended vehicle trajectory that is overlaid onto data indicative of the space.
