How Fast Humans Can React to Road Hazards
Anew study by MIT researchers shows humans need about 390 to 600 ms to detect and react to road hazards, given only a single glance at the road. The results indicate that younger drivers are quicker at both tasks: Older drivers (55 to 69 years old) required 403 ms to detect hazards in videos, and 605 ms to choose how they would avoid the hazard. Younger drivers (20 to 25 years old) only needed 220 ms to detect and 388 ms to choose from.
When a child runs onto the road, it takes an average of 1.6 seconds for a human driver to hit the brakes. Self-driving cars equipped with radar or lidar sensors and a camera system have a reaction time of 0.5 seconds. A self-driving car can react much faster than humans.
Reaction time is also a critical factor when drivers are tired. Self-driving cars ensure drivers will have enough time to safely take the controls and steer clear of unexpected hazards. Let’s look at how self-driving cars can offer better safety protection. Read More...
