Vehicle Navigation Traffic Information Filtering and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems face inefficiencies in transmitting and displaying traffic information to vehicles, often inundating users with redundant data, wasting bandwidth, and requiring vehicles to sift through unnecessary information, which hampers effective route determination and user understanding.
Innovation Solution
A system utilizing a one-to-many communication network for broadcasting traffic information and a two-way communication network for personalized updates, featuring a user display that filters and presents relevant traffic flow and incident information efficiently, including pop-up windows and scrollable options, to provide clear and concise navigation guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same traffic information is transmitted to all vehicles, then all vehicles receive traffic information, but many vehicles are inundated with unwanted traffic information and bandwidth is wasted
Solution Approach 1:
The system transmits traffic information selectively to specific vehicles based on their location and route needs. The server determines which vehicles require which traffic information and transmits only that information, rather than broadcasting to all vehicles. This localized approach ensures reliable delivery of relevant information while minimizing bandwidth waste by avoiding transmission to vehicles that do not need the information.
2Loss of information
If one-to-one communication is used to send vehicle-specific traffic information, then each vehicle receives relevant information, but the same regional traffic information is transmitted multiple times to different vehicles
Solution Approach 1:
The system merges traffic information transmission by sending a single copy of regional traffic information to multiple vehicles simultaneously through broadcast or multicast communication. The server identifies vehicles that need the same traffic information and transmits it once to all of them, rather than sending separate copies to each vehicle. This combining approach maintains information relevance for each vehicle while dramatically reducing bandwidth consumption.
3Loss of information
If all traffic information is displayed to the user, then complete information is provided, but the user is overwhelmed with redundant and superfluous information
Solution Approach 1:
The system extracts and displays only the relevant traffic information for the user's current route and location, filtering out redundant and superfluous information. The navigation device processes the received traffic information and selectively presents only those updates that affect the user's planned route or current position. This extraction approach maintains information completeness for route determination while greatly improving ease of operation by presenting a manageable, relevant subset to the user.
4Ease of operation
If traffic information is filtered to show only relevant data, then user understanding is improved, but route determination may miss important traffic updates
Solution Approach 1:
The system segments traffic information processing into two distinct functions: complete information reception for route determination, and selective display for user presentation. The navigation device receives and processes all relevant traffic information to maintain accurate route determination, using this complete data set for route calculations. Simultaneously, it segments the display function to show only the most relevant updates to the user. This segmentation ensures that route determination reliability is maintained through complete information processing while user interface clarity is improved through selective presentation.

AI summary
Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. The traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system. The user display may also automatically display traffic flow and traffic incident information for the direction that the user is traveling or along a route calculated by the navigation device. Further, a window displaying information about an upcoming traffic incident such as distance to the incident and incident details may automatically appear in the user display. Alternately, the user may select a roadway, freeway, or area for which traffic information is desired.
