1. A warning system for alerting a Vulnerable Road User (VRU) of a predicted collision, the warning system comprising:
at least one input device for transmitting a first input signal associated with a first vehicle positioned in a first lane of a roadway and a second input signal associated with a second vehicle positioned in a second lane of the roadway adjacent to the first lane, wherein the at least one input device is a sensor mounted to the first vehicle;
an Ultra Wideband beacon (UWB beacon) attached to the first vehicle, the UWB beacon for communicating with an Ultra Wideband tag (UWB tag) of a VRU notification device that is carried by the VRU, and a location of the UWB tag being trackable by way of a third input signal;
a light projector disposed on the first vehicle, the light projector configured to project a light in an outboard direction from the first vehicle;
a computer attached to the first vehicle, the computer comprising:
at least one processor communicating with the at least one input device and receiving the first and second input signals from the at least one input device, and the at least one processor further communicating with the UWB beacon and receiving the third input signal from the UWB beacon; and
a non-transitory computer readable storage medium (CRM) for storing instructions, such that the at least one processor is programmed to:
determine a location of the VRU in response to the at least one processor receiving the third input signal from the UWB beacon;
determine the predicted collision between the second vehicle and the VRU at a predicted collision site within a predicted time-to-collision based on the second and the third input signals; and
command the light projector to project light in the outboard direction from the first vehicle indicative of the predicted collision;
generate a notification actuation signal in response to the at least one processor determining the predicted collision, with the notification actuation signal associated with the VRU positioned at a tracked location; and
transmit, using the UWB beacon, the notification actuation signal to the VRU notification device in response to the at least one processor determining that the location of the VRU notification device and the tracked location of the VRU notification device are matching one another;
where the VRU notification device compares the location of the VRU notification device to the tracked location associated with the notification actuation signal, in response to the VRU notification device receiving the notification actuation signal from the at least one processor; and
where the VRU notification device notifies the VRU that the second vehicle is headed toward the predicted collision site in a crosswalk in response to the VRU notification device determining that the location of the VRU notification device matches the tracked location of the VRU notification device.
