Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing risk of collisions between personal transport devices and parked vehicles due to inadequate infrastructure that fails to account for these devices in urban environments, leading to increased safety concerns for users.
Innovation Solution
A parked vehicle warning infrastructure system that includes warning lights and a control system capable of communicating with personal transport devices and vehicles, using information about parked vehicles and personal transport devices to determine the location of warning lights and illuminate them to alert users of potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning lights are installed at all locations near roadways, then safety coverage is improved, but infrastructure complexity and cost increase
Solution Approach 1:
The control system pre-determines and stores optimal locations for warning lights based on historical collision data and roadway characteristics. When a personal transport device approaches a parked vehicle, the system activates only the pre-positioned warning lights at the specific location where the hazard exists, rather than requiring warning lights at every possible location along the roadway.
Solution Approach 2:
The system uses data from the personal transport devices and vehicles themselves to trigger warnings only when and where needed. The infrastructure serves itself by using the presence and movement information of the devices to determine when activation is necessary, eliminating the need for continuous operation or manual intervention.
2Reliability
If warning lights are activated continuously, then visibility and warning effectiveness are improved, but energy consumption increases
Solution Approach 1:
Instead of continuous activation, the warning lights operate periodically or on-demand based on detected conditions. The control system monitors the environment and activates lights only during periods when a personal transport device is approaching a parked vehicle, creating an intermittent activation pattern that reduces energy consumption while maintaining effectiveness when needed.
Solution Approach 2:
The system receives feedback from personal transport devices about their location, speed, and trajectory. This feedback loop allows the control system to make real-time decisions about when activation is necessary, ensuring lights are on only during critical moments when a warning can actually prevent a collision, rather than operating continuously.
3Measurement precision
If the system monitors all personal transport devices and vehicles, then collision detection accuracy is improved, but information processing requirements increase
Solution Approach 1:
The control system focuses processing resources on local areas where hazards are detected rather than uniformly monitoring all roadways. When a parked vehicle is identified as a potential hazard, the system intensifies monitoring and processing for personal transport devices in the immediate vicinity of that specific hazard, while reducing processing for areas without known hazards.
Solution Approach 2:
The monitoring system divides the roadway into multiple zones or segments, each with its own hazard assessment. Rather than processing information from all devices across the entire roadway simultaneously, the system segments the problem into manageable geographic or functional units, processing information locally for each segment and only activating warnings where collisions are actually predicted.

AI summary
A system and method for providing a parked vehicle warning infrastructure is described. In one embodiment, a method for providing a warning about parked vehicles includes receiving information associated with at least one of a parked vehicle or a personal transport device. The method also includes determining a location of one or more warning lights disposed in or near a roadway associated with the parked vehicle or the personal transport device. The method further includes sending an instruction to the one or more warning lights to illuminate. The illuminated one or more warning lights provide a warning to a user of the at least one of the parked vehicle or the personal transport device about a risk of a collision between the parked vehicle and the personal transport device.
