Wireless Traffic Alert Transceivers for Emergency Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for communicating cautionary and emergency notifications are limited by the need for recipients to be attentive and receptive, and often rely on infrastructure that may not be available or reliable, particularly in vehicular environments where external noise and distractions are prevalent.
Innovation Solution
A self-contained, wireless communication system using transmitters, receivers, and transceivers that can operate independently of infrastructure, utilizing technologies like ZigBee for point-to-point communication, capable of interrupting existing audio or video systems to deliver alerts via audio and visual messages within a defined range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alert systems (sirens, visual signs, radio) are used, then coverage area is large, but reliability is low because recipients must be attentive and infrastructure may not be available
Solution Approach 1:
The patent introduces wireless transceivers as intermediary devices that relay emergency notifications between the alert system and recipients. These transceivers receive notifications from a central source and automatically transmit them to designated recipients' devices, eliminating the need for direct line-of-sight or infrastructure dependency on traditional sirens and radio systems.
Solution Approach 2:
The notification system is designed to operate autonomously without requiring recipient attention or action. The transceivers automatically receive, process, and transmit notifications based on pre-configured parameters, and the system self-manages message routing and delivery confirmation without human intervention in the communication path.
2Reliability
If comprehensive intelligent transportation systems are deployed, then notification coverage is complete, but cost and infrastructure requirements are extremely high
Solution Approach 1:
The patent divides the notification system into independent, modular transceiver units that can be deployed individually or in networks. Each transceiver operates as a standalone device with its own transmission and reception capabilities, allowing incremental deployment without requiring a comprehensive infrastructure overhaul. This segmentation enables cost-effective implementation while maintaining reliable coverage.
Solution Approach 2:
The transceiver devices are designed to handle multiple functions including receiving emergency notifications, transmitting alerts to multiple recipients, providing two-way communication, and operating across different environments. This multi-functionality reduces the need for specialized equipment and lowers overall system costs while maintaining comprehensive coverage capability.
3Ease of operation
If external alert systems are used, then notification reach is broad, but effectiveness is low due to noise and distractions in vehicular environments
Solution Approach 1:
The system transitions from broad external alert transmission to localized point-to-point communication. Each notification is specifically targeted to individual transceivers within a defined geographic radius of the emergency event, ensuring that alerts are delivered only to affected areas rather than being broadcast broadly where they compete with ambient noise and distractions.
Solution Approach 2:
The patent replaces mechanical acoustic alert systems (sirens, horns) with electronic wireless communication transceivers that transmit digital notifications. This substitution eliminates the limitations of acoustic propagation through noisy vehicular environments, as electronic signals are not affected by external noise, weather conditions, or physical obstacles in the same way acoustic waves are.

AI summary
A traffic calming (broadly defined as methods and apparatus for the purpose of reducing or otherwise controlling vehicle speeds and improving safety appropriate to the state of the road), cautioning, early warning and emergency notification system using secure wireless transmitters, receivers and transceivers for localized point to point notification. Static, desktop, portable and vehicle mounted transmitters/transceivers are automatically or manually triggered to transmit cautioning, early warning or emergency alert messages within a specified range to desktop, portable or vehicular-mounted receivers/transceivers, notifying the user of the receiver/transceiver of an approaching traffic calming or cautioning situation (children crossing, train crossing, construction detour, accident scene, etc.) or emergency situation (approaching emergency responder vehicle, such as police, firefighters, ambulance, etc). The system utilizes secure, localized point-to-point wireless technology to overcome typical impediments to effective targeted traffic calming, cautioning, early warning and emergency notification at home, work and in a vehicle by allowing emergency responders and others responsible for cautioning, early warning and emergency notification, who have one or more transmitter/transceiver, to communicate directly and effectively with the immediately affected individual(s) within a specified range, who have at least one receiver/transceiver.
