Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current road traffic control systems face challenges such as manual operation, lack of flexibility, and safety risks due to reliance on personnel to adjust traffic sign settings, especially during peak hours or adverse weather conditions.
Innovation Solution
A road traffic control system that uses a mobile terminal to transmit parameter data to a fixed terminal, which then automatically adjusts traffic sign instructions in real-time via a communication network, reducing the need for manual intervention and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual control by personnel is used to adjust traffic sign waiting time, then flexibility and adaptability to traffic conditions are improved, but time consumption, manual operation complexity, and safety risks increase
Solution Approach 1:
The traffic sign system automatically adjusts its own waiting time based on real-time traffic flow detection without requiring manual intervention. The system serves itself by using detected traffic conditions to autonomously modify operational parameters, eliminating the need for personnel to manually adjust settings while maintaining adaptability to changing traffic conditions.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where traffic flow is continuously detected and fed back to the control unit, which automatically adjusts waiting time based on this feedback. This real-time feedback loop enables the system to adapt to traffic conditions dynamically while eliminating manual operation and reducing time consumption.
2Productivity
If personnel manually adjust traffic signs at specific times to save manpower, then operational cost is reduced, but flexibility and timeliness are lost
Solution Approach 1:
The traffic sign system performs self-adjustment of waiting time based on real-time traffic detection, eliminating the need for personnel intervention. The system automatically serves its own operational needs by using detected traffic conditions to modify its parameters, maintaining full flexibility while achieving manpower efficiency.
Solution Approach 2:
The system transitions from static, pre-scheduled adjustments to dynamic, real-time automatic adjustment. The waiting time is continuously modified based on current traffic conditions rather than following a fixed schedule, enabling the system to adapt flexibly to changing conditions while operating without manual intervention.
3Reliability
If relevant personnel conduct on-site traffic command during high traffic flow, then direct control capability is improved, but safety risks and operational complexity increase
Solution Approach 1:
The system replaces the mechanical/manual control system with an automated electronic control system. Instead of personnel physically adjusting traffic signs on-site, the system uses electronic detection and automatic control units to adjust waiting time, eliminating the presence of personnel in dangerous traffic environments while maintaining effective control.
Solution Approach 2:
The system introduces an intermediary automated control unit between the traffic detection system and the traffic sign adjustment. This intermediary component processes detection data and automatically executes control decisions without requiring human intervention in the field, reducing safety risks while maintaining control effectiveness.
4Productivity
If traffic sign waiting time is extended to accommodate high traffic flow, then traffic congestion is reduced, but vehicle waiting time increases
Solution Approach 1:
The system dynamically adjusts waiting time based on real-time traffic conditions rather than using fixed extended waiting times. When traffic flow is high, the system automatically extends waiting time to prevent congestion; when traffic is light, it reduces waiting time to minimize vehicle delay, optimizing the balance between traffic flow efficiency and vehicle waiting time.
Solution Approach 2:
The system changes the waiting time parameter dynamically based on detected traffic flow conditions. The control unit modifies the waiting time parameter in real-time according to actual traffic conditions, allowing the system to extend waiting time when necessary to prevent congestion while reducing it when traffic is light, thus optimizing overall system performance.
