Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current vehicle sensors are used to detect incoming traffic, then traffic detection is provided, but the recognition accuracy is inadequate and driver intentions cannot be properly understood
Solution Approach 1:
A neural network processor is introduced as an intermediary between traditional sensors and traffic control decisions. The neural network receives sensor data about traffic conditions and driver actions, processes this information to recognize traffic patterns and driver intentions with high accuracy, then outputs control decisions for traffic lights. This intermediary system bridges the gap between basic sensor detection and sophisticated intention recognition.
Solution Approach 2:
Traditional mechanical and electronic sensor systems are replaced with a neural network-based computational system. Instead of relying solely on conventional sensors and simple control logic, the patent employs neural networks that can learn from data and make intelligent decisions about traffic flow, enabling accurate recognition of complex traffic patterns and driver intentions.
2Productivity
If traffic light control systems use fixed algorithms, then implementation is simple, but traffic flow optimization is insufficient and wait times are increased
Solution Approach 1:
The traffic light control system transitions from fixed, static algorithms to dynamic, adaptive control based on real-time neural network processing. The system continuously monitors traffic conditions, driver actions, and traffic flow patterns, adjusting traffic light sequences dynamically to optimize throughput and minimize wait times for all traffic directions.
Solution Approach 2:
The neural network processor receives continuous feedback about traffic conditions, vehicle positions, and traffic flow patterns from sensors, processes this information in real-time, and adjusts traffic light control decisions accordingly. This closed-loop feedback mechanism enables the system to adapt to changing traffic conditions and optimize flow dynamically.
3Productivity
If neural network technology is implemented for real-time traffic control, then traffic flow management is significantly improved, but device complexity increases
Solution Approach 1:
The traffic control system is segmented into distinct functional modules: sensor arrays for data collection, a dedicated neural network processor for intelligent decision-making, and traffic light control outputs. This modular architecture allows the complex neural network functionality to be isolated in a separate processing unit, simplifying the overall system design and enabling independent optimization of each component.
Solution Approach 2:
The neural network processor serves multiple functions within the traffic control system, including recognizing traffic patterns, detecting driver intentions, predicting traffic flow, and making real-time control decisions. This multi-functional approach consolidates various control functions into a single intelligent processing unit, reducing the need for multiple specialized devices.
4Adaptability or versatility
If current sensor systems are used, then basic traffic detection is provided, but comprehensive traffic control functionality is not achieved
Solution Approach 1:
The neural network processor performs preliminary analysis and prediction of traffic conditions, driver intentions, and potential conflicts before traffic light changes are effected. By anticipating future traffic states and preparing appropriate control responses in advance, the system can respond more reliably and accurately to complex and changing traffic conditions.
