UWB Vehicular Access Control for Venue Traffic Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large venues with extensive parking lots face challenges in managing entry and exit flow control, leading to significant vehicular traffic congestion when many vehicles attempt to access or leave simultaneously.
Innovation Solution
A vehicular access control system utilizing ultra-wideband (UWB) communication technology to identify vehicle location and manage access through a network of access control devices equipped with processors, communication interfaces, and actuating mechanisms, allowing vehicles to request permission to exit and directing them to specific access points based on their location and dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional barrier control systems are used at venue access points, then access control can be provided, but significant vehicular traffic congestion occurs when large numbers of vehicles attempt to enter or exit simultaneously
Solution Approach 1:
The system performs preliminary actions by detecting vehicles approaching the barrier using UWB technology before they reach the access point. The user device transmits access requests in advance, allowing the system to process authentication and prepare barrier activation before the vehicle arrives, thereby eliminating waiting time and maintaining high throughput.
Solution Approach 2:
The system implements feedback by continuously monitoring vehicle location via UWB communication and dynamically controlling barrier activation based on real-time vehicle presence detection. The barrier is activated only when a vehicle is detected and authenticated, creating a responsive feedback loop that optimizes access control efficiency and prevents congestion.
2Productivity
If multiple access control devices are deployed to handle high traffic volume, then vehicle throughput increases, but system complexity and infrastructure requirements increase
Solution Approach 1:
The system uses UWB communication technology as an intermediary between user devices and access control devices. This intermediary layer enables precise vehicle location detection and authentication without requiring complex infrastructure modifications. The UWB technology mediates the interaction, allowing multiple access points to coordinate efficiently while maintaining manageable system complexity.
3Productivity
If manual access control procedures are used, then system complexity is minimized, but traffic flow efficiency and wait times are significantly degraded
Solution Approach 1:
The system implements self-service by enabling vehicles to automatically transmit access requests through UWB communication without requiring manual intervention. The user device autonomously initiates authentication when the vehicle approaches, and the barrier is automatically activated upon verification, eliminating the need for manual access control procedures while maintaining high efficiency.
