Abstract: Traffic alert devices and methods of using the same are disclosed. A traffic alert device includes a housing having a first surface to face in a first direction toward a first area, and a directional motion sensor carried by the housing. The sensor monitors motion in a second area different than the first area, the second area being in a second direction angled relative to the first direction. The traffic alert device further includes a light emitter carried by the housing, the light emitter positioned to emit light that emanates from the first surface. The light emitter generates a visual signal in response to the sensor detecting an object in the second area approaching the sensor.
