Navigation System Traffic Delay Relevance Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to effectively inform users about traffic delays that are relevant to their current route, often making icons visible only when the user is close to the delay incident, which can be too late to change the route and avoid the delay.
Innovation Solution
A method that determines the relevance of traffic incidents based on their position and expected delay, communicating only the most relevant incidents to the user, either through text, graphics, or a combination of both, and providing periodic updates to help users anticipate and prepare for total expected delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traffic delay icons are displayed on the map when the user approaches the delay incident, then the user can see the delay incident information, but it is too late to change the route and avoid the delay
Solution Approach 1:
The system performs preliminary action by displaying traffic delay icons proactively before the user reaches the delay incident location. The icon is displayed when the vehicle is within a predetermined distance threshold of the delay incident, giving the user advance notice and sufficient time to react and change the route if desired, rather than waiting until the user is already at the incident location.
2Loss of information
If all delay incidents are communicated to the user, then the user receives complete information, but it interferes with the providing of usual route information and is difficult to understand
Solution Approach 1:
The system applies the extraction principle by selectively extracting and displaying only the most relevant traffic delay information. Instead of presenting all delay incidents, the system identifies and extracts key delay incidents that are closest to the user's current position and most likely to impact the route, displaying them in a simplified format that does not interfere with usual route information provision.
Solution Approach 2:
The system applies local quality by providing different levels of information detail in different contexts. The display shows simplified delay incident icons and basic information in the main route view, while allowing the user to access more detailed information about specific delay incidents through interactive elements, thus maintaining clarity while providing complete information on demand.

AI summary
A method of indicating traffic delays in a navigation system for planning a route of a vehicle is provided. The method comprises a step of receiving traffic information with position information of each one of a number of delay incidents, a step of determining a position of the vehicle on a planned route, a step of determining a relevance of each one of the delay incidents on the planned route based on the position information of the respective delay incident and on the position of the vehicle, a step of selecting at least one delay incident on the planned route, based on the determined relevance of the respective delay incident, and a step of communicating information concerning the selected delay incident to a user. The method provides an intuitive and user-friendly way of informing the user about delays to be expected.
