Vehicle Traffic Data System Using GPS Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems are limited by the data provided by suppliers and have restricted data transmission capacity, which may not include operator-specific traffic information, leading to suboptimal route planning and lack of real-time updates.
Innovation Solution
A system that allows operators to input and allocate attribute data to location data, using a computer-based navigation system to generate and communicate personalized traffic information, including environmental and driving-specific data, which can be updated in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traffic data is received from external information stations via radio (RDS/TMC), then traffic information can be obtained, but the data transmission capacity is restricted to about 320 to about 430 traffic announcements per minute
Solution Approach 1:
The patent uses GPS satellites as an intermediary to transmit traffic data. Instead of relying on the limited RDS/TMC radio system, the invention receives traffic information directly from GPS satellites, which have much higher data transmission capacity and can provide unlimited traffic announcements per minute, thereby resolving the bottleneck of the radio-based system.
2Adaptability or versatility
If digital map data is stored on a storage medium, then route calculation can be performed, but there may not be enough memory to store operator-specific traffic information
Solution Approach 1:
The patent extracts traffic data from the limited onboard storage memory and relocates it to the GPS satellite system. By receiving traffic information directly from satellites, the system eliminates the need to store large amounts of operator-specific traffic data locally, thereby resolving the memory capacity constraint while maintaining full adaptability to operator preferences.
3Ease of operation
If conventional navigation systems use supplier-provided traffic data, then basic routing is available, but operator-specific traffic information is not included leading to suboptimal route planning
Solution Approach 1:
The patent implements a feedback mechanism where the system receives and processes operator preferences and characteristics, then uses this information to customize traffic data reception and route planning. The GPS-based system continuously adapts to operator-specific needs by filtering and prioritizing traffic information based on individual preferences, thereby eliminating the information loss inherent in conventional supplier-provided data systems.
Data Source
AI summary
A system that communicates traffic data to a vehicle is presented. The system generally includes a method that communicates traffic data to an operator of the vehicle. The system provides location data to a computer-based system, and allocates attribute data to a subset of the location data. The allocation may be initiated by the operator. The traffic data is processed by the computer-based system, and/or communicated to the operator. The system may further include a device that provides traffic data to the operator. The traffic data device generally includes a locator for providing location data, an allocator for allocating attribute data to a subset of the location data, a storage medium for storing the generated traffic data, and an output device.
