As pedestrian fatalities continue to rise, auto makers are looking for ways to reduce the death toll and also avoid crashes completely.
According to NBC News, both Toyota and Ford unveiled new systems that detect when a person is walking in front of a vehicle.
The Toyota Pre-Collision System, or PCS, scans the road ahead of the car. It then issues an audio and visual alert to the driver. If the driver does not react in time, the car will try to steer away from the pedestrian.
Ford unveiled its concept last week in Europe. The design uses sensors and a camera to scan the road and can avoid a collision if it seems imminent.
More than 4,400 pedestrians died in the United States in 2001.
