Mobile Device Processor Personalized Traffic Event Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable navigation devices (PNDs) do not receive beneficial information when traveling familiar routes, as they often do not utilize navigation devices even when they could benefit from turn-by-turn guidance and other features, especially when they already know the route.
Innovation Solution
A mobile device processor generates and displays a list of 'no-jam events' and 'probable jam events' relevant to the user's current location, determining probability and relevance scores based on road segment analysis, allowing for personalized traffic and travel information without requiring users to input their destination, and prioritizing information based on user behavior and route history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users travel familiar routes without inputting destinations, then the device cannot provide personalized traffic information, but users still need relevant travel information without having to actively engage with the device
Solution Approach 1:
The system automatically determines the user's current route and provides traffic information without requiring explicit user input. The processor detects GPS signals to obtain current location, retrieves stored route information from memory, and automatically identifies which route the user is currently traveling on, thereby providing self-service functionality
Solution Approach 2:
The system continuously monitors the user's current location via GPS and compares it with stored route data to dynamically determine whether the user is on a familiar route. This feedback mechanism allows the system to adaptively provide traffic information based on the user's actual travel status without requiring active user engagement
2Quantity of substance
If the device provides all available traffic information, then users receive comprehensive data, but the information becomes overwhelming and not tailored to user needs
Solution Approach 1:
The system provides different types of traffic information based on the specific context of the user's current route. For familiar routes, it provides targeted traffic updates specific to that route, while for unfamiliar routes, it provides different information. This local quality approach ensures information is tailored to the specific travel context rather than providing uniform information for all situations
Solution Approach 2:
The system segments traffic information based on the user's current route and provides only the relevant segments. By dividing the overall traffic data into route-specific portions and selectively presenting only the information pertaining to the user's current travel path, the system avoids overwhelming the user with unnecessary data while maintaining personalization
3Ease of operation
If the device requires users to input destinations to receive traffic information, then information can be personalized, but users traveling familiar routes do not utilize the device even when they could benefit from guidance
Solution Approach 1:
The system pre-stores multiple routes in memory during a setup phase, including both familiar and unfamiliar routes. By having this route information prepared in advance, the system can automatically recognize which stored route the user is currently traveling on and provide appropriate traffic information without requiring the user to input destination details at the time of travel
Solution Approach 2:
The system automatically determines the user's current route by comparing real-time GPS location data with stored route information, and autonomously provides traffic updates without requiring user interaction. This self-service approach makes the device easily accessible to users traveling familiar routes while still delivering personalized information

AI summary
A method of providing traffic information is described, together with a device for performing the same. The method comprises determining a location of a mobile device, receiving traffic information, and determining, with respect to a trip database storing information indicative of a personal road network of a user of the mobile device, whether traffic information associated with one or more road segments in the personal network within a predetermined distance of the current location has been received. One or more no-jam events are generated for respective road segments in the personal network for which it is determined that no traffic information has been received.
