Parking Lane Assignment Based on Vehicle Weight and User Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to effectively utilize a limited parking lot area by not considering the varying use time periods based on the number of users, leading to inefficient allocation of space.
Innovation Solution
An information-processing device and vehicle control system that determine the number of users and vehicle weight to optimize lane selection within a parking lot, directing vehicles to shorter or longer stay lanes based on these factors, and implementing a penalty system for excessive stop times to manage traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are directed to different lanes based on number of users or weight, then parking lot space utilization is improved, but system complexity increases due to multiple controllers and determination parameters
Solution Approach 1:
The parking lot area is segmented into multiple lanes (first lane for short-term parking, second lane for long-term parking) based on vehicle characteristics. The system divides the parking management function into a first controller for determining vehicle characteristics and a second controller for determining lane assignment, allowing specialized processing in each segment while maintaining overall system efficiency.
Solution Approach 2:
The system uses parameter changes (number of users or weight) to determine vehicle parking needs. By measuring these parameters and comparing them against threshold values, the system dynamically assigns vehicles to appropriate lanes, optimizing space utilization without requiring complex manual assessment procedures.
2Productivity
If threshold values are set for lane selection, then lane assignment efficiency is improved, but measurement precision requirements increase for accurate user number or weight determination
Solution Approach 1:
The system employs threshold values for determination parameters (number of users or weight) to simplify lane assignment decisions. By setting predetermined thresholds, the system converts continuous parameter measurements into discrete lane selection decisions, improving assignment efficiency while maintaining acceptable precision through clear decision boundaries.
Solution Approach 2:
The system can determine the number of users by measuring vehicle weight and creating a correspondence between weight data and user number data. This indirect measurement approach allows efficient lane assignment without requiring direct counting of users, reducing measurement complexity while maintaining determination accuracy.
3Productivity
If penalty system is implemented for delay actions, then traffic flow management is improved, but device complexity increases due to additional controller functions
Solution Approach 1:
The system implements a penalty determination function that monitors vehicle stop times in each lane and applies penalties when vehicles exceed appropriate duration thresholds. This feedback mechanism ensures that vehicles use the correct lane for their intended parking duration, improving traffic flow management by preventing lane misuse and ensuring efficient space utilization.
Solution Approach 2:
The penalty determination function is integrated into the existing second controller that handles lane assignment. By combining the lane determination function and penalty determination function in a single controller, the system avoids adding separate dedicated penalty controllers, thereby reducing overall system complexity while still implementing effective traffic flow management.

AI summary
An information-processing device includes a first controller configured to determine the number of users using a vehicle that enters or leaves a parking lot or a weight of the vehicle and a second controller configured to determine a position where the vehicle is stopped within a predetermined area of the parking lot on the basis of the number of users or the weight determined by the first controller.
