Prioritized Traffic Data Broadcasting for Vehicle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems are inundated with redundant and superfluous traffic information, making it inefficient for vehicles to receive relevant and prioritized route guidance.
Innovation Solution
A system and method for prioritizing and broadcasting traffic information to vehicles, where an information center generates and relays data messages based on road type and relevance to the vehicle's route, ensuring that higher priority information is broadcast first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the same traffic information is transmitted to many or all vehicles in a given geographic region, then the information coverage is comprehensive, but many vehicles are inundated with a large amount of redundant and superfluous information
Solution Approach 1:
The patent applies local quality by customizing traffic information transmission according to each vehicle's specific characteristics, including its geographic location, route, destination, and vehicle type. Instead of uniform broadcasting to all vehicles, the system tailors the information content to match local needs of each vehicle, thereby reducing redundant information while maintaining comprehensive coverage of relevant traffic data.
Solution Approach 2:
The system changes parameters such as information priority levels, transmission frequency, and data selection criteria based on vehicle-specific parameters like route importance, traffic conditions, and vehicle type. This dynamic parameter adjustment allows the system to optimize information delivery by transmitting only the most relevant data to each vehicle, reducing overall data volume while preventing information loss.
2Loss of information
If all traffic information is broadcast to vehicles, then complete traffic data is provided, but users and navigation systems must sift through redundant information to pick out pertinent traffic information
Solution Approach 1:
The patent implements preliminary action by pre-processing and prioritizing traffic information before transmission to vehicles. The system预先 (in advance) determines which traffic information is relevant to each vehicle based on their route, location, and destination, and assigns priority levels to different information types. This preliminary filtering and organization eliminates the need for users and navigation systems to sift through redundant information, while ensuring complete delivery of pertinent traffic data.
3Productivity
If traffic information is prioritized and filtered before broadcasting, then data efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary component (traffic information management system) that acts as a mediator between the traffic data source and vehicles. This intermediary system performs the complex tasks of filtering, prioritizing, and customizing information based on vehicle characteristics, thereby simplifying the overall architecture. The intermediary handles the computational complexity centrally, allowing individual vehicles to receive pre-processed, optimized information without requiring complex onboard processing capabilities.
Data Source
AI summary
Systems and methods are provided for prioritizing traffic information and broadcasting the traffic information in a prioritized order. The method generally comprises receiving data regarding traffic conditions on various roads, wherein each road can be characterized as being a major, medium, or minor road. In one approach, traffic data regarding major roads are broadcast to vehicles first, followed by traffic data regarding medium roads, while traffic data regarding minor roads are either broadcast last or not at all, depending on the traffic information handling capacities of the vehicles and the traffic information system in general.
