Lane Guidance System Adjusting Recommendations by Intersection Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane guidance systems often mislead users by forcing them to change lanes, especially when there is traffic congestion, as they only recommend one lane, which can lead to undesirable lane changes.
Innovation Solution
A lane guidance system and program that determine the distance between successive intersections and adjust the proposed lane based on this distance, recommending a specific lane when the distance is short to avoid confusion and allowing users to choose when the distance is longer, thereby reducing the likelihood of misleading lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single recommended lane is always proposed, then the guidance is clear and decisive, but the user may be misled into unnecessary lane changes or changes to congested lanes
Solution Approach 1:
The system dynamically adjusts the lane recommendation strategy based on the distance to the next intersection. When the distance is short (within threshold), it provides a single recommended lane for clarity. When the distance is long (beyond threshold), it provides multiple travelable lanes for user choice, preventing misleading recommendations.
Solution Approach 2:
The system changes the parameter of lane recommendation (from single to multiple options) based on the distance parameter to the next intersection. This parameter-based adaptation resolves the contradiction by selecting the appropriate guidance mode according to the spatial context.
2Adaptability or versatility
If multiple travelable lanes are always proposed, then the user has more choices and control, but the guidance becomes less decisive and may cause confusion
Solution Approach 1:
The system dynamically switches between providing multiple lane options and providing a single recommended lane based on the distance to the next intersection. This dynamic adjustment ensures clarity when needed (short distance) while providing versatility when appropriate (long distance).
Solution Approach 2:
The recommendation mode parameter changes based on the distance parameter. When distance exceeds the threshold, multiple lanes are presented for user versatility. When distance is within threshold, a single lane is recommended for operational clarity.
3Manufacturing precision
If the system forces lane changes based on single lane recommendation, then the proposed route is followed accurately, but traffic congestion may worsen and user experience deteriorates
Solution Approach 1:
The system dynamically adjusts its guidance strictness based on distance to intersection. Near intersections (short distance), it enforces single lane recommendation for route accuracy. Far from intersections (long distance), it allows multiple options to avoid forcing unnecessary lane changes that cause congestion and poor user experience.
Solution Approach 2:
The guidance mode parameter changes based on the distance parameter to balance route following accuracy with avoidance of harmful effects. The threshold-based parameter change prevents forced lane changes in situations where they are unnecessary.

AI summary
Provided is lane guidance system for decreasing the possibility that a user is misled including: a proposed travel route acquisition unit that acquires a proposed travel route of a vehicle; a successive intersection determination unit that determines whether a distance between a first intersection that is a guidance intersection on the proposed travel route and a second intersection that follows the first intersection is within a prescribed distance. Based on the proposed travel route, a travelable lane acquisition unit acquires a travelable lane that the vehicle needs to travel along when entering the first intersection to exit in a specific exiting direction of the first intersection, when the vehicle needs to exit from the first intersection in the exiting direction to travel along the proposed travel route. Before arriving at the first intersection, the lane guidance unit selects and proposes, as a recommended lane from the travelable lane, a lane that the vehicle needs to travel along when entering the first intersection after exiting from the first intersection, a lane that the vehicle needs to travel along when entering the second intersection to exit in a specific exiting direction of the second intersection, when the vehicle needs to exit from the second intersection in the exiting direction to travel along the proposed travel route when the a distance between the first intersection and the second intersection is within a prescribed distance.
