Devices, systems, and methods are provided for alerting a pedestrian, such as a visually impaired pedestrian, of a vehicle in the vicinity. In general, signals are transmitted from a vehicle to a device carried by a pedestrian, such as a mobile terminal. In response, the pedestrian's device may generate an alarm, such as a vibration or an audible alarm, informing the pedestrian that a vehicle is nearby. In some cases, the pedestrian's device may transmit activation signals to the vehicle after receiving the signals from the vehicle. The activation signals may cause speakers on the vehicle to emit an audible alarm, alerting the pedestrian of the presence of the vehicle.
