Traffic Controller Dual-Transmission Cellular RF Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic control systems are not equipped to handle emergency response vehicles effectively, leading to unsafe scenarios due to reliance on sirens and lights, and lack integration with modern communication technologies, resulting in inefficient and unsafe traffic management.
Innovation Solution
Implementing a system that allows traffic controllers to communicate with vehicles and pedestrians using cellular and radio frequency data to modify traffic light states and provide real-time traffic information, enabling safer and more efficient traffic management through simultaneous RF and cellular signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional traffic control systems use only sirens and lights for emergency vehicles, then the system complexity remains low, but the safety and effectiveness of emergency response is insufficient
Solution Approach 1:
The patent combines multiple communication technologies (cellular and RF) into a single traffic control system. The emergency vehicle communication system integrates both cellular transmitters/receivers and RF transmitters/receivers to communicate with traffic controllers, creating a more reliable and safe system for emergency response while accepting increased system complexity.
2Area of stationary object
If traffic controllers communicate with mobile devices using only cellular signals, then the communication range is extended, but the reliability in areas with poor cellular coverage is reduced
Solution Approach 1:
The patent segments the communication function into two separate systems: cellular communication for extended range and RF communication for reliable local communication. The traffic controller system includes both cellular transmitters/receivers and RF transmitters/receivers, allowing it to use cellular signals when range is needed and RF signals when reliability is needed, particularly in areas with poor cellular coverage.
3Adaptability or versatility
If the system processes signals from multiple sources simultaneously, then the traffic management becomes more adaptive, but the signal processing complexity increases
Solution Approach 1:
The patent introduces a cloud-based server as an intermediary to handle the complex signal processing. The traffic controllers communicate with the server, which processes signals from multiple sources (emergency vehicles, mobile devices, traffic sensors) and coordinates the responses. This mediator approach allows the system to be highly adaptive while distributing the processing complexity to a centralized cloud infrastructure rather than requiring complex processing at each traffic controller.
Data Source
AI summary
Systems, methods, and devices are disclosed for improving traffic safety and efficiency. The system includes various signal transmitters and receivers positioned throughout roadways, within automobiles, in smartphones, or supported by a cellular network backbone, for distributing traffic related information to users and traffic controller equipment. Embodiments of the present disclosure allow for vehicles and/or pedestrians to initiate a dual-transmission of cellular and RF signals for changing a traffic light state, where the first signal received at a traffic intersection controller unit is processed for changing the traffic light state (e.g., changing a light from red to green on-demand). Other embodiments of the present disclosure allow for users to receive visible and/or audible traffic related alerts on mobile devices, where the alerts are based on data shared between nearby drivers, pedestrians, and the traffic controlling equipment.
