US 2019/0197640 A1 · FLOCK-BASED CROWD MOVEMENT ANALYSIS FOR PREDICTIVE CONFLICT IDENTIFICATION IN A SAFETY RESPONSE SYSTEM

Abstract

Approaches presented herein enable predictive conflict identification in a safety response system. More specifically, a likely intersection location of two or more flocks of people is determined based on predicted travel vectors of the flocks. Information about attributes of the people in each of the flocks is obtained to determine whether a potential conflict exists between the intersecting flocks. These flock attributes are analyzed, with attributes indicative of a potential conflict between the flocks being assigned a greater weight than attributes not indicative of a potential conflict. Based on the analysis, a conflict factor score is assigned to the intersection of the flocks. A security authority is then selectively informed by a generated notification, in the case that it is determined that the conflict factor meets or exceeds a predetermined security threshold, of the predicted intersection of the flocks.

Dependent claims

A method for predictive conflict identification in a safety response system, comprising:

determining, based on a predicted travel vector of a first flock and a predicted travel vector of a second flock, an intersection location of the first flock and the second flock;
obtaining attribute information associated with people of the first flock and people of the second flock;
analyzing the obtained attribute information to determine a conflict factor between the first flock and the second flock;
determining whether the conflict factor exceeds a predetermined security threshold;
and
selectively generating, responsive to a determination that the conflict factor exceeds the predetermined security threshold, a notification.

3 more elements

A safety response computer system for predictive conflict identification, the computer system comprising:

a memory medium comprising program instructions;
a bus coupled to the memory medium;
and
a processor, for executing the program instructions, coupled to a predictive conflict identification engine via the bus that when executing the program instructions causes the system to:
determine, based on a predicted travel vector of a first flock and a predicted travel vector of a second flock, an intersection location of the first flock and the second flock;
obtain attribute information associated with people of the first flock and people of the second flock;
analyze the obtained attribute information to determine a conflict factor between the first flock and the second flock;
determine whether the conflict factor exceeds a predetermined security threshold;
and
selectively generate, responsive to a determination that the conflict factor exceeds the predetermined security threshold, a notification.

7 more elements

A computer program product for predictive conflict identification in a safety response system, the computer program product comprising a computer readable hardware storage device, and program instructions stored on the computer readable hardware storage device, to:

determine, based on a predicted travel vector of a first flock and a predictive travel vector of a second block, an intersection location of the first flock and the second flock;
obtain attribute information associated with people of the first flock and people of the second flock;
analyze the obtained attribute information to determine a conflict factor between the first flock and the second flock;
determine whether the conflict factor exceeds a predetermined security threshold;
and
selectively generate, responsive to a determination that the conflict factor exceeds the predetermined security threshold, a notification.
