Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lane splitting by motorcyclists is perilous due to the unpredictability of surrounding vehicle movements, leading to a high risk of collisions, particularly in congested traffic situations.
Innovation Solution
A collision avoidance system for motorcycles that uses vehicle sensors and processors to capture data, estimate vehicle trajectories, and generate warnings when the predicted future distance between vehicles is unsafe for lane splitting, utilizing various sensor technologies like LIDAR, RADAR, and optical cameras to provide timely alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If motorcyclists perform lane splitting to bypass congested traffic, then productivity is improved by reducing travel time, but safety deteriorates due to unpredictable vehicle movements and collision risks
Solution Approach 1:
The system performs preliminary detection of traffic conditions and gap analysis before the motorcyclist commits to the lane splitting maneuver. Sensors continuously monitor the space between vehicles ahead, and the system evaluates whether the gap is sufficient and stable for safe passage, providing advance warning or authorization to the rider before entering the lane split position.
Solution Approach 2:
The system provides real-time feedback to the motorcyclist about the safety of lane splitting conditions. Based on sensor data measuring the distance and relative motion of surrounding vehicles, the system communicates whether the current gap is safe for lane splitting, allowing the rider to make informed decisions and adjust behavior accordingly.
2Productivity
If drivers in adjacent lanes reduce the space between vehicles to improve traffic flow efficiency, then productivity is improved, but safety deteriorates by closing the gaps needed for safe lane splitting
Solution Approach 1:
The system detects and evaluates potential gap closures by surrounding vehicles before they become hazardous. By continuously monitoring the relative position and speed of vehicles in adjacent lanes, the system identifies when gaps are shrinking and provides early warning to the motorcyclist, enabling preventive action before the situation becomes dangerous.
Solution Approach 2:
The system takes preliminary anti-action by alerting the motorcyclist to impending gap closures, allowing the rider to adjust their position or abort the lane splitting maneuver before the hazardous condition develops. This proactive warning system counteracts the harmful effect of closing gaps by enabling timely rider response.
3Reliability
If motorcyclists execute abrupt maneuvers to avoid collisions, then safety is improved by preventing accidents, but reliability deteriorates due to the forced nature of these emergency actions
Solution Approach 1:
The system performs preliminary assessment of lane splitting safety, allowing the motorcyclist to plan and execute smooth, controlled maneuvers rather than forced emergency actions. By providing advance information about gap safety, the rider can gradually adjust position and speed, maintaining vehicle stability and rider control throughout the maneuver.
