Abstract

A system for security screening at a venue includes one or more security screening stations, each station having a security level and configured to screen a plurality of subjects in a queue for admitting the subject to the venue. The system may determine the current queue length of all the queues associated with security screening stations based on data received from one or more sensors. The system may also determine whether the throughput for at least one security screening station should be increased or decreased. If the system so determines, the system may decrease or increase, for a variation time period, the security level of the security screening station associated with the queue. The system may also adjust configuration of the stations or place a secondary and complementary screening process to dynamically improve the performance of the security system.

determine a current queue length of all the queues associated with the one or more security screening stations,

determine whether a throughput for at least one security station of the one or more security screening stations should be increased or decreased,

change, for a variation period, a security level of the at least one security screening station upon determining that the throughput for the at least one security station should be increased or decreased from an original value to an adjusted value, and

when the variation period expires;

return the security level to the original value, and

repeat the steps of receiving, determining the current queue length, determining whether the throughput for at least one security station of the one or more security screening stations should be increased or decreased, and changing.

2. The system of claim 1, wherein the security level of the security screening station is a sensitivity level associated with a detector of the security screening station.

3. The system of claim 1, wherein programming instructions for determining whether the throughput for at least one security station of the one or more security screening stations should be increased or decreased are configured to make the determination based on one or more of:

a maximum security wait time for the venue;

a combined size of all of the queues associated with all the security screening stations;

a desired overall level of detection; and

the security level of all other queues associated with all of the one or more security screening stations.

4. The system of claim 3, wherein programming instructions for adjusting the security level of the security screening station are configured to decrease or increase the original value of security level by an amount so that an overall average security is maintained at an acceptable level.

5. The system of claim 4, wherein the overall average security is the overall level of detection.

6. The system of claim 1, wherein programming instructions for determining whether the throughput for at least one security station of the one or more security screening stations should be increased or decreased are configured to make the determination based on one or more of:

information about national security;

statistics about security settings of the system in past events similar to a current event; and

subject-specific information related to one or more patrons waiting in the queue associated with the one or more security screening stations.

7. The system of claim 6, wherein subject-specific information related to one or more patrons comprises an identification of a person, a license plate number of a vehicle, or information about past violation by a person.

8. The system of claim 1, wherein the variation period is a random time period corresponding to a time less than the current estimated wait time of the at least one security screening station.

9. The system of claim 1, wherein programming instructions comprise additional programming instructions that, when executed, will cause the processor to:

upon determining that the throughput for at least one security station of the one or more security screening stations should be decreased or increased, adjust a configuration of the one or more security screening stations at the venue.

10. The system of claim 9, wherein programming instructions for adjusting the configuration of security screening stations comprise:

determining that a security screening station should be closed; and

transmitting a signal to the security screening station that should be closed, wherein the signal, when received by the security screen station, causes the security screening station to close.

11. The system of claim 9, wherein programming instructions for adjusting the configuration of security screening stations comprise:

determining that a security screening station should be closed; and

transmitting a signal to a signage indicating that an operator closes the security screening station.

12. The system of claim 9, wherein programming instructions for adjusting the configuration of security screening stations comprise:

determining that a new security screening station should be opened; and

transmitting a signal to the new security screening station, wherein the signal, when received by the security screening station, will cause the security screening station to open.

13. The system of claim 9, wherein programming instructions for adjusting the configuration of security screening stations comprise:

determining that a new security screening station should be opened; and

transmitting a signal to a signage indicating that an operator opens the security screening station.

14. A security screening station having an adjustable security level and configured to screen a plurality of subjects in a queue associated with the security screening station, the security station comprising:

one or more sensors configured to measure a queue length of a queue associated with the security screening station;

a processor;

a non-transitory computer-readable storage medium containing programming instructions that, when executed, will cause the processor to;

determine whether a throughput for the security screening station should be increased or decreased based on a reading from the one or more sensors,

adjust, for a variation period, the security level of the security screening station upon determining that the throughput for the security screening station should be increased or decreased from an original value to an adjusted value, and

when the variation period expires;

return the security level to the original value, and

repeat the steps of determining and adjusting.

15. The security screening station of claim 14, wherein programming instructions for adjusting the security level of the security screening station comprise programming instructions configured to cause a sensitivity level of a detector of the security screening station to increase or decrease.

16. The security screening station of claim 14, wherein the variation period is shorter than a waiting period that corresponds to a queue length of a queue associated with the security screening station.

17. The security screening station of claim 14, further comprising a communication interface, configured to receive a queue length of a queue associated with an additional security screening station, wherein programming instructions for adjusting the security level of the security screening station comprise additional programming instructions configured to adjust the security level of the second security screening station also based on the queue length associated with the additional security screening station.

19. The method of claim 17, wherein the security level of the security screening station is a sensitivity level associated with a detector of the security screening station.
