Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crowd management systems for mass gatherings lack reliable methods to quantify, predict, and track participant movements and behavior, leading to increased risks of accidents due to congestion and unpredictable crowd behavior, with insufficient data for effective decision-making.
Innovation Solution
A system utilizing network sensors and image acquisition devices to collect data from electronic devices, processed through supervised and unsupervised learning models to provide real-time, corrected distribution data, enabling dynamic management and predictive analytics for crowd control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional crowd management techniques (entry/exit controls, temporary channels) are used, then crowd control is simplified, but crowd movements between control points cannot be managed and control points become congestion points
Solution Approach 1:
The system divides the gathering area into multiple virtual zones using image acquisition devices, enabling granular monitoring and control of crowd distribution across different spatial segments rather than relying on single control points
Solution Approach 2:
The patent replaces physical control mechanisms (barriers, channels) with an information-based system using image acquisition devices and processing units to monitor and manage crowd movements, eliminating the need for physical infrastructure between control points
2Measurement precision
If passive RFID tags are used for pilgrim identification, then individual tracking is enabled, but detection failures occur in high density or when people are in vehicles
Solution Approach 1:
The system uses image acquisition devices that can detect and track both individuals and groups simultaneously, making the system universally applicable whether people are moving individually or in vehicles, eliminating the detection failures associated with RFID tags
Solution Approach 2:
The patent introduces image acquisition devices as an intermediary between the tracking system and the crowd, using visual recognition to identify and track participants without relying on electronic tags that may be obscured or inactive
3Measurement precision
If wireless sensor networks with GPS modules are used, then location tracking is achieved, but the system complexity and energy consumption increase
Solution Approach 1:
The system combines multiple image acquisition devices into a unified monitoring network, merging their data through a central processing unit to achieve comprehensive location tracking without requiring complex individual tracking devices for each participant
4Device complexity
If no data collection system is used, then the system remains simple, but accurate quantification of participant distribution and movement is impossible
Solution Approach 1:
The system creates a virtual copy of the physical crowd through image acquisition and data processing, generating a digital representation of participant distribution and movement that can be analyzed without physically interfering with or complicating the actual crowd
