Dynamic Road Surface Marking for Pedestrian Lane Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surface marking systems fail to effectively notify pedestrians of lane changes, leading to situations where pedestrians remain in prohibited traffic lanes after switching, potentially causing safety hazards.
Innovation Solution
An information processing apparatus and road surface marking system that detect remaining pedestrians in prohibited lanes and generate urging markings to guide them to safe lanes by changing light emission patterns and using cameras or sensors to specify the remaining area and provide guidance markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the road surface marking system changes light emission patterns to switch traffic lanes, then the adaptability of traffic lane configuration is improved, but pedestrians may remain in prohibited lanes without timely notification, worsening safety
Solution Approach 1:
The control unit continuously monitors the road surface area for remaining pedestrians after lane switching and provides feedback by displaying urging markings when pedestrians are detected, creating a closed-loop safety notification system
Solution Approach 2:
The system displays urging markings in advance before the lane switching is fully completed, notifying pedestrians of the upcoming prohibition and giving them time to evacuate the area
2Object-affected harmful factors
If the system displays urging markings to notify remaining pedestrians, then pedestrian safety is improved, but the device complexity increases due to additional detection and control functions
Solution Approach 1:
The control unit performs multiple functions: controlling the light emitters for lane configuration, detecting remaining pedestrians through image processing, and displaying urging markings, consolidating these functions into a single control system
Solution Approach 2:
The system uses its own existing camera and display capabilities to detect pedestrians and provide safety notifications, rather than requiring completely separate detection and notification subsystems
3Measurement precision
If the system uses camera-based detection to identify remaining pedestrians, then detection precision is improved, but the loss of time increases due to image processing requirements
Solution Approach 1:
The control unit starts capturing images and processing them immediately after lane switching begins, performing detection work in advance rather than waiting until the switching is complete
Solution Approach 2:
The image capture and processing operates continuously during and after the lane switching process, ensuring no detection gaps without requiring repeated full-processing cycles
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures pedestrians are reliably notified and guided to safe lanes, enhancing safety and efficiency in lane changes by using dynamic markings and real-time detection.
Implementation Method 1
The road surface marking apparatus is configured to change the number and/or the types of traffic lanes formed on the road by changing light emission patterns of a plurality of light emitters provided on a road surface
Data Source
AI summary
An information processing apparatus controls a road surface marking apparatus configured to form any road surface marking by changing light emission patterns of a plurality of light emitters provided on a road surface. In the information processing apparatus, a control unit detects, when switching from a second traffic lane through which a pedestrian is allowed to pass to a first traffic lane through which a pedestrian is prohibited from passing is executed, a user who is a pedestrian remaining in the first traffic lane after the switching. Then, the control unit causes the road surface marking apparatus to form an urging marking used for urging the user to withdraw from the first traffic lane after the switching.
