Traffic Information Output System for Route Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic information output systems burden users by requiring them to repeatedly specify a start time when searching for alternative routes to avoid congestion, making the process cumbersome and inconvenient.
Innovation Solution
A traffic information output system that includes an input device, an output device, a storage unit for change patterns of moving costs, and a moving cost prediction unit, which allows users to shift the reference time point by a specified time to predict and display moving costs, thereby simplifying the process of selecting a new route with reduced user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation device displays the moving cost difference to allow the operator to perceive travel time changes due to congestion, then the operator can search for alternative routes to avoid congestion, but the operator is bothered by having to specify a start time point repeatedly when searching for another route
Solution Approach 1:
The system performs preliminary action by automatically setting the start time point based on the current time or previously specified time, eliminating the need for the operator to repeatedly specify the start time point when searching for alternative routes. The controller automatically calculates and displays moving cost differences for multiple time points, allowing the operator to select from pre-calculated options without manual time specification.
2Reliability
If the system provides detailed traffic information and moving cost differences for route selection, then the operator can make informed decisions about avoiding congestion, but the system complexity increases with multiple time point calculations and displays
Solution Approach 1:
The system segments the time dimension by dividing the route search into multiple discrete time points (e.g., current time, future time points). The controller calculates moving cost differences for each segmented time point independently, allowing detailed traffic information to be provided without overwhelming system complexity. Each time point segment can be processed and displayed separately, making the complex information manageable for the operator.

AI summary
There is provided a traffic information output system capable of reducing or eliminating the burden on a user when the searched route and the traffic information on the route are outputted. The traffic information output system comprises a moving cost prediction unit 213 which predicts a moving cost of the route according to a reference time point indicated in a change pattern, and a moving cost output control unit 214 which outputs, to the output device, the prediction moving cost and change time point interfaces P27 and P28 for outputting a prediction moving cost which is a moving cost predicted according to a post-change reference time point.
