Vehicle Speed Detection System with Compliance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed detection systems fail to provide real-time warnings to vehicle users about exceeding location-based speed limits, often relying on roadside cameras that punish after the fact and lack adaptability to varying locations and user responses.
Innovation Solution
A system comprising position providing means, determining means, comparison means, signalling means, and compliance means that use GPS data to detect vehicle location and speed, compare it with location-based speed limits, generate warnings or control signals, and monitor user compliance, allowing for adaptive warnings and vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roadside speed cameras are used to detect and punish speeding, then speed limit enforcement is achieved, but real-time warnings to drivers are not provided and the system lacks adaptability to varying locations
Solution Approach 1:
The portable device integrates multiple functions into a single unit: GPS reception for location tracking, speed detection for monitoring vehicle speed, database storage for speed limit references, and warning signal generation for real-time alerts. This multi-functional integration enables the system to adapt to various locations and provide comprehensive speed management capabilities.
Solution Approach 2:
The system automatically receives GPS data to determine its location, queries the database for applicable speed limits, compares current speed with limits, and generates warnings without requiring manual intervention. This self-service operation enhances adaptability to different locations while maintaining reliable enforcement.
2Adaptability or versatility
If portable devices with GPS and speed detection are used, then real-time warnings and adaptability to locations are achieved, but device complexity increases
Solution Approach 1:
The patent combines GPS reception, speed detection, database storage, and warning signal generation into a single integrated portable device. This merging of previously separate functions reduces the overall system complexity while maintaining real-time warning capabilities and location adaptability.
Solution Approach 2:
The portable device is designed as a multi-functional unit that performs location tracking, speed monitoring, database querying, and warning generation simultaneously. This universal design approach consolidates multiple components into one device, managing complexity while enhancing adaptability.
3Reliability
If compliance monitoring is added to track user response to warnings, then user compliance can be ensured, but device complexity and processing requirements increase
Solution Approach 1:
The system incorporates compliance monitoring that tracks whether drivers respond to warnings by reducing speed. This feedback mechanism provides information about driver behavior, enabling the system to adjust warnings and improve compliance while managing processing requirements through efficient monitoring algorithms.

AI summary
Provided is an apparatus and a method for detecting a speed of a vehicle, and also providing a warning to the vehicle if the vehicle is travelling above a location-based imposed speed limit. The apparatus and method also make use of a compliance means that determines whether, or not, a user actively complies with the warning that is generated, thereby ensuring that a user is correctly adhering to the legally imposed speed limits.
