Navigation Device Traffic Data via Server Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems using the TPEG protocol struggle to provide accurate, real-time traffic information, making it difficult for drivers to identify actual traffic conditions effectively, especially when conditions change rapidly.
Innovation Solution
A method and device that utilize a wireless communication device to receive and provide traffic condition data from a content managing server, integrating this data with map information to offer users precise and efficient traffic updates, including CCTV and variable message sign data, through a navigation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time traffic information is received through TPEG protocol, then traffic information can be obtained, but it fails to reflect traffic conditions varying fast and is difficult to identify actual traffic conditions in a specific position
Solution Approach 1:
The patent introduces a server as an intermediary between the navigation device and traffic information sources. The server receives map data from the navigation device, acquires corresponding traffic condition data from various sources, and returns processed information. This intermediary approach enables more accurate and timely traffic condition identification by centralizing data processing and coordination.
Solution Approach 2:
The patent transitions from traditional TPEG protocol to a three-dimensional data architecture involving map data, traffic condition data, and their spatial relationships. By integrating traffic information with specific map coordinates and locations, the system achieves precise identification of traffic conditions at specific positions rather than providing generic traffic updates.
2Ease of operation
If traffic information is provided with location association, then users can identify traffic conditions more efficiently, but the system complexity increases
Solution Approach 1:
The server acts as a mediator that handles the complex tasks of data acquisition, processing, and location association. By offloading these complex operations to a centralized server, the navigation device itself remains relatively simple while still providing enhanced location-associated traffic information to users.
Solution Approach 2:
The system divides functionality into separate modules: map data management, traffic condition data acquisition, location association processing, and user information delivery. This segmentation allows each component to specialize in specific tasks, making the overall system more manageable and easier to implement despite the increased functionality.
Data Source
AI summary
A traffic condition data providing method using a wireless communication device and a navigation device performing the method are disclosed. The navigation device includes a travelling path displaying unit that searches a travelling path to a destination set by a user and displays the travelling path on map data, a traffic condition data receiving unit that receives traffic condition data from a content managing server through a wireless communication device in response to a request of providing the traffic condition data over the travelling path, and a traffic condition data providing unit that provides the user with the received traffic condition data.
