A warning system is provided for alerting a Vulnerable Road User (VRU) of a predicted collision. The system includes one or more input devices for transmitting a first input signal associated with a first vehicle positioned in a first lane, a second input signal associated with a second vehicle positioned in a second lane, and a third input signal associated with the VRU located on a crosswalk that extends across the first and second lanes. The system further includes a computer having a processor and a non-transitory computer readable medium. The processor is programmed to determine the predicted collision between the second vehicle and the VRU at a predicted collision site. The processor is further programmed to generate an actuation signal. One or more roadway notification devices notify the VRU that the second vehicle is positioned in the second lane and headed toward the predicted collision site in the crosswalk.
