Low-Cost LoRaWAN Vehicle Detection System for Urban Traffic Management: A Cost-Driven Design Approach with Field Validation
SSRN · 6285119
The Takeaway
Before this, smart city traffic management was gated by massive infrastructure budgets required for inductive loops or high-bandwidth camera networks. This system uses LoRaWAN and low-power magnetic sensors to slash deployment costs by over 90% while maintaining a field-validated accuracy of 94.7%. It shifts the bottleneck from expensive hardware and power cabling to a lightweight, battery-operated mesh that can be installed in minutes. This means urban planners in budget-constrained environments can finally implement high-density data collection that was previously financially impossible. For practitioners, this unlocks the ability to build a real-time traffic grid for an entire metropolitan area on a fraction of a traditional budget.
From the abstract
Urban traffic management systems face significant challenges in deployment costs and scalability, particularly in developing regions where traditional monitoring technologies remain economically prohibitive. This paper presents a novel cost-driven design approach for vehicle detection, integrating LoRaWAN (Long Range Wide Area Network) technology with AMR (Anisotropic Magnetoresistance) magnetic sensors specifically optimized for low-cost urban traffic monitoring. Our system achieves a deploymen
