Vehicle Return Route Guidance System for Park-and-Ride
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the park-and-ride system, users face low convenience when returning rented vehicles due to potential delays in reaching the parked vehicle, leading to the possibility of missing the designated return time, as existing user support techniques do not accurately account for dynamic changes in the time needed to move to the vehicle.
Innovation Solution
An information processing system and server that estimate the user's current transportation means and decide routes to both the parked vehicle and the return location, providing timely guidance to ensure arrival within the target time by outputting route information via the user's terminal device or vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is given to the user based on the needed time for moving to a predetermined destination using the vehicle, then the user can be informed of the schedule, but the user may be unable to arrive at the destination on time due to dynamic changes in the needed time for moving to the parked vehicle
Solution Approach 1:
The system dynamically updates the needed time for moving to the parked vehicle based on real-time changes in user conditions, such as current position and selected transportation means. This allows the notification timing to adapt to actual circumstances rather than relying on fixed estimates, thereby improving arrival time reliability while maintaining user convenience.
Solution Approach 2:
The system provides feedback to the user by notifying them of the updated needed time and suggesting appropriate transportation means to reach the parked vehicle on time. This closed-loop approach allows the user to adjust their actions based on system recommendations, ensuring reliable arrival while preserving ease of operation.
2Measurement precision
If the needed time for moving to the parked vehicle is calculated based on fixed assumptions, then the calculation is simple, but the accuracy of predicted arrival time deteriorates due to dynamic user actions
Solution Approach 1:
The system preliminarily determines various transportation means and calculates the needed time for each option before the user actually travels. This allows the system to present multiple possibilities and their respective arrival times in advance, improving measurement precision without requiring complex real-time calculations during the actual journey.
Solution Approach 2:
The system dynamically recalculates the needed time based on the user's actual position and selected transportation means. Rather than using fixed assumptions throughout, the system updates its calculations as conditions change, thereby improving arrival time accuracy while keeping the computational complexity manageable through incremental updates.

AI summary
An information processing system acquires positional information of a vehicle, acquires positional information of a terminal device, estimates current transportation means of a user based on the positional information of the terminal device, decides information relating to a first route, along which the user moves to the vehicle, based on the positional information of the terminal device, the estimated current transportation means of the user, and the positional information of the vehicle, decides information relating to a second route, along which the user who has moved to the vehicle moves to a destination using the vehicle, based on a first predicted arrival time, the positional information of the vehicle, and positional information of the destination, and outputs first guide information for prompting the user to start moving along the first route in a form of a video or a sound.
