Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic signals for pedestrians lack the ability to proactively provide duration information for passing and fail to effectively communicate pedestrian intentions to drivers, especially with the increasing use of smart devices that may distract pedestrians from traffic states.
Innovation Solution
A traffic information interaction system that includes lighting apparatuses and electronic devices capable of emitting light signals indicating passable or not passable states, and allowing electronic devices to transmit requests to adjust these signals, enabling proactive information push and pedestrian intention communication without needing a central control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional traffic signals use only lighting signals to indicate passable paths, then the system is simple, but pedestrians cannot obtain duration information and may overlook traffic states when using mobile devices
Solution Approach 1:
The patent introduces electronic devices (smartphones, tablets) as intermediary components between the traffic signal system and pedestrians. These devices receive traffic state information from the lighting apparatus via wireless communication and display it to pedestrians, serving as a mediator that delivers information without requiring direct interaction with the traffic signal infrastructure.
Solution Approach 2:
The patent replaces the traditional mechanical button press system with an electronic communication system. Instead of requiring physical button presses at the traffic signal, pedestrians use electronic devices to send requests wirelessly to the lighting apparatus, substituting mechanical interaction with electronic data transmission.
2Ease of operation
If conventional systems require button presses to notify pedestrian intention, then the infrastructure is simple, but pedestrians using mobile devices cannot easily indicate their intention and drivers cannot know about pedestrian intentions
Solution Approach 1:
The patent replaces the mechanical button press system with an electronic communication system. Instead of requiring physical button presses at the traffic signal, pedestrians use electronic devices to send requests wirelessly to the lighting apparatus, substituting mechanical interaction with electronic data transmission.
Solution Approach 2:
The electronic device serves as an intermediary that captures pedestrian intention through input operations and transmits it to the lighting apparatus via wireless communication, bridging the gap between pedestrian intent and traffic signal response without requiring direct physical interaction with the signal infrastructure.
3Device complexity
If no central control system is used, then the system complexity is reduced, but coordination between lighting apparatus and electronic devices becomes challenging
Solution Approach 1:
The lighting apparatus autonomously processes received requests from electronic devices and independently adjusts its pushed information accordingly. Each lighting apparatus operates as a self-contained unit that can interpret and respond to pedestrian requests without requiring centralized control, enabling distributed autonomous operation.
Solution Approach 2:
The system implements a feedback loop where the lighting apparatus receives requests from electronic devices, adjusts its information pushing behavior in response, and continues to monitor for additional requests. This closed-loop feedback mechanism ensures reliable coordination without centralized control.

Function Achieved in This Case
Enhances pedestrian safety by clearly indicating traffic states and durations to nearby devices, allowing pedestrians to plan their passage and alerting drivers of potential pedestrians, thereby reducing accidents and improving traffic awareness.
Implementation Method 1
Each of the lighting apparatuses emits light according to received power, so as to indicate whether a corresponding path is passable with the emitted light
Data Source
AI summary
A traffic information interaction system is provided. The system includes a plurality of lighting apparatuses and a first electronic device. Each of the lighting apparatuses emits light according to received power, so as to indicate whether a corresponding path is passable with the emitted light. In addition, each of the lighting apparatuses further pushes information. The first electronic device generates a request according to received information, and transmits the request to a target lighting apparatus of the lighting apparatuses. The target lighting apparatus adjusts target information pushed by the target lighting apparatus according to the request.
