Navigation Control Unit Optimizing Departure Time for Road Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices cannot provide a travel schedule that allows users to arrive at their destination as comfortably as possible by minimizing time spent on the road, as they typically prioritize arrival time over reducing traffic congestion impacts.
Innovation Solution
An information processing apparatus that determines a movement schedule by storing congestion information by time zone and calculating a route and schedule that allows users to arrive within a predetermined time threshold, prioritizing comfort by reducing labor for the driver and avoiding busy times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional navigation devices prioritize arrival time, then users can reach their destination by the deadline, but users spend excessive time on the road due to traffic congestion
Solution Approach 1:
The navigation device dynamically adjusts the recommended departure time based on real-time traffic congestion data and user preferences. Instead of providing a fixed schedule, the system continuously optimizes the departure time to balance road time reduction with deadline compliance, allowing flexible adaptation to changing traffic conditions while ensuring the user arrives by the desired deadline.
2Ease of operation
If users depart earlier to avoid traffic congestion, then road time is reduced, but the flexibility of departure time selection is limited
Solution Approach 1:
The system incorporates user feedback regarding preferred departure time ranges and provides feedback about traffic conditions to suggest optimal departure times. The navigation device learns from user responses to suggestions and adjusts future recommendations, creating a feedback loop that progressively improves both flexibility and road time reduction based on user preferences and actual traffic patterns.

AI summary
An information processing apparatus comprises a storage unit configured to store congestion information for each road link by time zone; and a control unit configured to obtain information about a departure place, a destination and an arrival deadline from a user, and to determine a route connecting between the departure place and the destination and a movement schedule including a departure time and an estimated arrival time; wherein the control unit determines the movement schedule that allow a user to arrive at the destination by the arrival deadline and to move through the route in a required time shorter than a predetermined value set for each route.
