Parking Space Detection System Using Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In urban areas, finding available parking spaces can be challenging, leading to prolonged vehicle circling, illegal parking, and traffic congestion, as existing systems lack efficient methods to locate unoccupied parking spots in real-time.
Innovation Solution
A system comprising vehicles and a server that collect and update parking environment data, using sensors and databases to determine occupancy status and predict availability of parking spaces, guiding vehicles to the nearest unoccupied spots through a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers manually search for parking spaces by circling the location, then they can potentially find available parking spots, but this leads to extended search time, increased traffic congestion, and higher fuel consumption
Solution Approach 1:
The system performs preliminary detection and recording of parking space occupancy status before drivers arrive. Sensors continuously monitor and update the database with current parking availability, so when drivers query the system, the information is already prepared and available, eliminating the need for manual searching and circling.
Solution Approach 2:
The system establishes a feedback loop where sensors detect parking space status, the server processes and stores this data, and the information is returned to drivers via user devices. This closed-loop feedback system ensures drivers receive real-time updates on parking availability, enabling them to navigate directly to open spaces without random searching.
2Reliability
If drivers circle extensively to find parking spaces, then they may locate unoccupied spots, but this generates traffic congestion and hinders overall traffic flow
Solution Approach 1:
The system introduces an intermediary infrastructure consisting of sensors, a server, and communication networks that mediate between parking spaces and drivers. This intermediary system provides reliable real-time parking information without requiring drivers to interact directly with parking spaces through circling, thus decoupling information acquisition from traffic-disrupting behavior.
Solution Approach 2:
The system replaces the mechanical searching behavior (drivers physically circling and visually inspecting for parking spaces) with an electronic information system. Sensors and communication networks substitute for the mechanical action of driving around, providing parking location data electronically rather than requiring physical exploration, thereby maintaining traffic flow efficiency.
3Measurement precision
If real-time parking data is collected and processed through a centralized server, then accurate parking space location information becomes available, but this increases system complexity and infrastructure requirements
Solution Approach 1:
The system segments the parking management function into independent modular components: detection sensors at individual parking spaces, a centralized server for data processing, and user interface devices for drivers. Each component performs a specific function independently, allowing the system to achieve high measurement precision through distributed sensors while managing complexity through modular architecture where each segment can be developed and maintained separately.

AI summary
The disclosure describes systems and methods that are configured to measure and generate parking environment data including locations of parking spaces and their occupancy status, and to use the parking environment data to find an unoccupied parking space for a vehicle. In particular, a system is configured to determine the location and occupancy status of parking spaces based on parking environment data received from a vehicle, and to determine a location of an unoccupied parking space based on a database of parking environment data.
