<h1>Ultra-Wideband (UWB) for Vulnerable Road User Protection:
Communication, Positioning, Simulation and Field Validation</h1>

<p>
Ultra-Wideband (UWB) technology enables highly accurate positioning,
secure ranging, and low-latency wireless communication. This project
investigates how UWB can improve the safety of Vulnerable Road Users (VRUs)
such as pedestrians, cyclists, and road workers by integrating positioning,
communication, simulation, and real-world experimentation.
</p>

<h2 id="background">Background and Motivation</h2>

<p>
Recent advances in IEEE 802.15.4z and IEEE 802.15.4ab have made UWB an
attractive technology for both communication and precise positioning.
Combined with Cooperative Intelligent Transport Systems (C-ITS),
UWB can support applications that increase awareness of vulnerable road users
and reduce accident risks.
