Vehicle-to-Vehicle Parking Vacancy Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide real-time information about parking lot vacancy status to drivers during their travel, as they rely on pre-accessed web services, which may not reflect current conditions due to the dynamic nature of parking availability.
Innovation Solution
A method where a vehicle acquiring data on a parking lot's vacancy status upon exit broadcasts this information to other vehicles, allowing them to request and share this data via vehicle-to-vehicle communication, ensuring up-to-date information is transferred to nearby vehicles within a predetermined period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If web services are used to provide parking lot vacancy status information, then information can be accessed beforehand, but the information may not reflect current conditions due to the dynamic nature of parking availability
Solution Approach 1:
The system performs preliminary actions by having the first vehicle acquire parking lot vacancy status data before exiting the parking lot. This pre-acquired data is then broadcast to other vehicles, ensuring that up-to-date information is available to surrounding vehicles before they need to make parking decisions, thus resolving the contradiction between information accuracy and update timing.
Solution Approach 2:
The first vehicle acts as an intermediary that bridges the gap between the parking lot management system and other vehicles seeking parking information. By acquiring data from the parking lot and broadcasting it to nearby vehicles, the first vehicle enables real-time information sharing without requiring all vehicles to directly access web services, thus improving both information freshness and system efficiency.
2Loss of information
If real-time information sharing among vehicles is implemented, then drivers receive accurate and timely information, but additional communication infrastructure and protocols are required
Solution Approach 1:
The system implements self-service by enabling vehicles to autonomously acquire, broadcast, and share parking lot vacancy status data without requiring complex centralized communication infrastructure. The first vehicle independently performs data acquisition and broadcasting functions, while other vehicles independently receive and utilize the information, reducing overall system complexity while improving information availability.
Data Source
AI summary
A first vehicle acquires first data about the vacancy status of a first parking lot when exiting from the first parking lot, broadcasts second data including an identifier of the first parking lot, and transmits, in response to a request transmitted from a second vehicle having received the second data, the first data to the second vehicle.
