To investigate vehicle-related countermeasures to reduce the risk of
young children being killed or injured by reversing motor vehicles,
particularly those on private driveways.
A review of technology for proximity sensors and
Measuring the rearward field of view for a range of vehicles,
Theoretical investigation to establish required detection
Acquiring and evaluating several proximity sensors and
visual aids and
Determining the improvement provided by these devices when
fitted to vehicles.
Conclusions (the emphasis has been added in response to
misleading claims about some types of equipment)
A slow moving vehicle is a deadly hazard for young children
due to the risk of them being knocked over and crushed by the wheels
Most cars and 4WDs have very poor rearward visibility for
detecting objects the size of toddlers
(parking aids) alone cannot provide
sufficient warning to drivers that a toddler is in the path of a
they are not a "safety
Lens type visual aids
are totally inadequate for detecting
children behind vehicles - the image is too small and
incident light on the lens can obscure the view.
A video camera system can provide the driver with a good
view to the rear except, possibly, for locations very close to the back
of the vehicle. In any case, there is also a need to alert the driver
if there is an object close to the back when reverse is first engaged.
A combination of video
camera and short-range proximity
would cover all critical blind spots at the rear (see diagram)
18 Sep 08 AAA Foundation: The AAA Foundation in collaboration with National Highway Traffic Safety Administration (NHTSA) recently completed a report on new car features and driving-aid technologies: Backing Aid Sensors and Rear-View Cameras:
They’re designed to assist the driver by warning as a vehicle backs
slowly toward an object, but they won’t detect everything in a
vehicle’s path. Most backing aid systems can’t detect a child,
object or animal directly underneath the bumper and don’t provide a
warning when a car is backing up at speeds faster than 3 to 6 mph.
There were several scenarios in which respondents reported that their
backing aid system would help them avoid a collision “fairly well” or
“perfectly,” when in reality it would be likely to work poorly or not
work at all.
