Dual assessment for early collision warning
First Claim
1. A system for facilitating warning of collision between a primary principal and one or more non-primary principals, comprising:
- a triggering mechanism configured to determine whether a trigger condition is met based on a state of the primary principal, wherein the state of a principal is represented by a geometric object which indicates a location of the principal at a given time interval; and
a preliminary assessment mechanism, wherein when the trigger condition is met, the preliminary assessment mechanism is configured to;
generate one or more collision scenarios associated with the trigger condition, wherein a collision scenario indicates a possible collision at a future state of the primary principal;
assess a preliminary probability of collision in a collision scenario, which involves determining that geometric objects for the primary principal and a non-primary principal intersect at a future state of the primary principal; and
based on the preliminary probability of collision in the collision scenario, activate a specialized assessment mechanism to assess a refined probability of collision in the collision scenario.

Abstract
One embodiment of the present invention provides a system that facilitates warning of collision between a primary principal and one or more non-primary principals. The system includes a triggering mechanism and a preliminary assessment mechanism. During operation, the triggering mechanism determines whether a trigger condition is met based on the state of the primary principal. When the trigger condition is met, the preliminary assessment mechanism generates one or more collision scenarios associated with the trigger condition, assesses a preliminary probability of collision in a collision scenario, and, based on the preliminary probability of collision in the collision scenario, activates a specialized assessment mechanism to assess a refined probability of collision in the collision scenario.
