Abstract
In one embodiment, a method includes a computing system obtaining, via one or more sensors of a personal mobile vehicle (PMV), a reflection signal indicating a characteristic of a road surface of an environment external to the PMV. The computing system may determine one or more characteristic factors of the road surface of the environment external to the PMV based on the reflection signal. The computing system may generate a vulnerable road user (VRU) classification probability distribution by using a machine learning classifier. The VRU classification probability distribution indicates whether a combination of the one or more characteristic factors is associated with the VRU. The computing system may determine, based on the VRU classification probability distribution, that the road surface is associated with the VRU. The computing system may present an alert message to a display associated with the PMV.
