Satellite Broadcast Traffic Camera Data Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems lack timely and accurate updates for traffic enforcement camera locations, with user-generated data being unreliable and not differentiated by type, leading to inefficiencies and false alarms.
Innovation Solution
A satellite/terrestrial network-based data service that provides verified traffic enforcement camera location data through an SDARS broadcast, distinguishing between camera types and allowing customizable warnings, using a database updated from reliable sources and stored in-vehicle for real-time alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GPS-based systems use user-generated camera location data, then the system can provide camera location information, but the data reliability deteriorates due to lack of verification and differentiation by camera type
Solution Approach 1:
The patent introduces a centralized database as an intermediary between camera operators and GPS-based detection systems. This database serves as a verified repository that filters and standardizes camera location data before distribution to users, eliminating the need for users to submit unverified data directly to the system.
Solution Approach 2:
The system enables automated data verification and differentiation through structured database entries that include camera type classification. The database automatically organizes data by camera type (speed camera, red light camera, etc.) and provides this differentiated information to GPS systems without requiring manual user verification or intervention.
2Reliability
If conventional systems update camera location data via internet downloads, then users can access updated data, but the updating process becomes complex and requires internet connectivity
Solution Approach 1:
The database is designed to serve multiple functions: storing verified camera location data, classifying data by camera type, providing automated updates to GPS systems, and enabling differentiation between camera types. This multi-functional database replaces complex internet-based update mechanisms with a unified data distribution system.
3Reliability
If GPS systems provide undifferentiated camera warnings, then all camera types are covered, but false alarms increase due to lack of camera type differentiation
Solution Approach 1:
The patent applies local quality by differentiating database entries according to camera type characteristics. Each camera location record includes specific attributes (speed camera, red light camera, etc.) that allow GPS systems to provide tailored warnings appropriate to each camera type, rather than uniform undifferentiated alerts.
Data Source
AI summary
An enhanced broadcast data service with reports locations of traffic enforcement camera locations (e.g., red light cameras and speed cameras) to users. Traffic enforcement camera information is aggregated, verified (e.g., particularly as to traffic enforcement camera type) and stored (e.g., at a server). A broadcast signal comprising program channels and at least one data channel having traffic enforcement camera information is transmitted to a plurality of receivers. Receivers store at least a subset of the traffic enforcement camera information available from the server and synchronize to it using periodic transmitted updates. Receivers compare receiver location data with stored camera location data, and display or generate audible alerts when the receiver is within a selected geographic range of a traffic enforcement camera. Alerts can be filtered as to camera type. A alerts can employ different color camera icons superimposed on a screen map depending on camera type or whether the camera is newly added.
