People Flow Control Evaluation Angular Difference Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing people flow control evaluation systems cannot accurately assess the impact of people flow control on individual activity changes, as they lack the capability to evaluate how effectively people are guided towards their destination.
Innovation Solution
A people flow control evaluation apparatus that includes a position obtaining unit to track the position of target individuals, a direction calculation unit to determine their movement directions, and an effect evaluation unit to calculate the angular difference between the individuals' movement directions and their intended destination paths, thereby evaluating the effectiveness of people flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If people flow control evaluation is performed using only area-based congestion degree and route-based delay time, then the evaluation covers overall people flow distribution, but the evaluation cannot accurately assess the impact on individual activity changes and destination guidance effectiveness
Solution Approach 1:
The patent segments the evaluation into multiple dimensions: area-based congestion degree, route-based delay time, and individual-based destination guidance effectiveness. By dividing the evaluation into these separate components, the system can assess both overall people flow distribution and individual activity changes without requiring a single overly complex evaluation metric.
Solution Approach 2:
The patent adds a new evaluation dimension by introducing destination guidance effectiveness based on angular difference calculation. This transforms the evaluation from traditional two-dimensional metrics (congestion and delay) to a three-dimensional assessment that includes directional accuracy, thereby improving comprehensive evaluation precision without merely increasing complexity.
2Measurement precision
If traditional evaluation metrics (congestion degree, delay time) are used, then the evaluation is simple to compute, but it cannot correctly evaluate whether people flow control effectively guided individuals to their destinations
Solution Approach 1:
The patent replaces traditional mechanical evaluation methods (area-based and route-based metrics) with a more advanced angular difference calculation method. This substitution enables the system to measure directional accuracy and destination guidance effectiveness by comparing movement directions with destination directions, providing a more precise evaluation of individual guidance effectiveness.
Solution Approach 2:
The patent introduces angular difference as an intermediary metric that bridges the gap between simple movement tracking and complex destination guidance evaluation. By calculating the angular difference between actual movement direction and destination direction, the system creates a measurable intermediate value that effectively assesses guidance effectiveness without requiring direct observation of destination arrival.

AI summary
A people flow control evaluation apparatus (100) evaluates an effect of people flow control. A position obtaining unit (110) extracts a position of a target person chronologically from people flow information (20) and stores the position of the target person as chronological position information (41). A direction calculation unit (120) calculates a movement direction of the target person chronologically based on the chronological position information (41) and stores the movement direction of the target person as a chronological movement direction (42). An effect evaluation unit (130) calculates an angular difference between the movement direction of the target person and a direction towards a destination position from the position of the target person chronologically, and evaluates the effect of the people flow control using a chronological change of the angular difference calculated chronologically.
