Pedestrian Group Restoration System for Traffic Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedestrian traffic flow is often hindered when a pedestrian trails behind a group, leading to vehicle congestion and safety risks, as vehicles must wait for the straggling pedestrian to cross.
Innovation Solution
A group restoration system that uses sensors to identify isolated pedestrians and employs visual/audible notifications and user device alterations to encourage them to join the group, thereby improving traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles wait for straggling pedestrians to cross, then safety is improved, but vehicle traffic flow deteriorates
Solution Approach 1:
The system performs preliminary detection of straggling pedestrians using sensors before they become a traffic hazard. By identifying isolated pedestrians early in their crossing path, the system can alert them proactively to join groups, preventing the safety-traffic flow conflict from arising in the first place.
Solution Approach 2:
The system implements feedback loops where sensor data about pedestrian positions and group formations continuously informs alert generation. When a straggler is detected, the system provides real-time feedback through alerts to encourage rejoining, and continues monitoring to confirm compliance, creating a closed-loop control system that dynamically balances safety and traffic flow.
2Object-affected harmful factors
If vehicles wait for isolated pedestrians, then accident risk is reduced, but crossing time increases
Solution Approach 1:
The system alerts isolated pedestrians in advance before vehicles need to stop, giving them time to join groups proactively. This preliminary warning action prevents the situation where vehicles must wait, thereby reducing both accident risk and crossing time by addressing the hazard before it materializes.
Solution Approach 2:
By providing timely alerts to stragglers, the system enables them to quickly join groups and complete their crossing faster. This allows the crossing process to rush through the critical phase where isolated pedestrians create hazards, minimizing the time vehicles need to wait while maintaining safety.
3Productivity
If the system provides continuous monitoring and alerts, then pedestrian traffic flow improves, but system complexity increases
Solution Approach 1:
The system uses existing sensor infrastructure and pedestrian-carrier devices to perform monitoring and alert delivery. Rather than requiring a completely new complex system, it leverages available resources (sensors, mobile devices) to provide the group restoration function, thereby improving traffic flow while limiting the increase in overall system complexity.
Solution Approach 2:
The system employs multi-functional components where sensors serve both autonomous vehicle navigation and pedestrian group monitoring purposes. The pedestrian carrier devices serve both as communication interfaces and as indicators of group presence. This universality allows the system to improve pedestrian traffic flow without proportionally increasing system complexity.

AI summary
Systems, methods, and other embodiments described herein relate to encouraging pedestrian group movement to enhance traffic flow. In one embodiment, a method includes identifying, based on sensor data, a movement behavior of a pedestrian. The method also includes classifying the pedestrian as being isolated from a group of pedestrians based on the movement behavior of the pedestrian and movement behavior of the group. The method also includes producing a group restoration countermeasure responsive to the pedestrian being classified as isolated from the group. The group restoration countermeasure encourages the pedestrian to join the group.
