V2X Roadside Unit Exit Coordination for Parking Lot Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-everything (V2X) networks, managing the exit of multiple vehicles from a parking area simultaneously can lead to congestion, as drivers and autonomous vehicles struggle to determine the optimal exit order and location, resulting in inefficient traffic flow.
Innovation Solution
A roadside unit (RSU) receives exit requests from vehicles, determines an exit order based on various criteria such as reception order, proximity to exits, vehicle size, and priority, and transmits exit commands to vehicles, including indications of the exit time and identification information of preceding vehicles, to manage the exit process efficiently.

Engineering Contradiction Analysis
1Productivity
If multiple vehicles attempt to leave a parking area simultaneously, then the exit process can be completed faster, but congestion occurs and traffic flow becomes inefficient
Solution Approach 1:
The system performs preliminary actions by having vehicles register their exit requests in advance and determining their exit order before actually exiting. The RSU receives exit requests from multiple vehicles, determines the optimal exit order based on various criteria (proximity to exit, vehicle size, priority), and notifies each vehicle of its assigned position. This preliminary organization prevents congestion during the actual exit process by ensuring vehicles leave in a pre-planned sequence rather than simultaneously or chaotically.
2Adaptability or versatility
If drivers and autonomous vehicles determine exit order independently, then each vehicle can make its own decision, but confusion arises and traffic efficiency decreases
Solution Approach 1:
The RSU acts as an intermediary between vehicles and the exit process. Instead of drivers or autonomous vehicles independently determining exit order (which causes confusion), the RSU receives exit requests from all vehicles, centralizes the decision-making process by determining the optimal exit order based on multiple criteria, and then communicates this determined order back to each vehicle. This intermediary coordination eliminates confusion while maintaining systematic control over the exit process.
3Device complexity
If vehicles exit without coordinated timing, then the exit process is simpler, but safety is compromised due to potential collisions and inefficient traffic flow
Solution Approach 1:
The system implements feedback mechanisms where the RSU receives exit requests from vehicles, determines the optimal exit order and timing, and then notifies each vehicle of its assigned exit position and timing. This feedback loop ensures that each vehicle has accurate information about when and in what order it should exit, improving safety by preventing collisions and inefficient traffic flow. The coordinated timing information provided to each vehicle enables them to execute their exit maneuvers safely and efficiently.
