Ultrasonics have played a huge role in transport safety to date – but with technology moving forward, and fatal flaws in their offerings, it looks like they’ll soon be obsolete. Our latest products, like TurnAware, use the newest and most radical technology to ensure road safety. Moving forward, the rest of our product range, and other companies, will follow suit, leaving behind ultrasonic sensors in the creation of cycle safety technology.
While ultrasonic sensors have certainly helped with road safety awareness and campaigns, they have too many flaws to make them a long-term solution. Being highly sensitive to any object – from bollards to cars and even pedestrians – the sensors were well known for causing false alarms. Of course, this alone causes its own problems. These false alarms can also make a vehicle more dangerous to passing cyclists as the driver takes his attention off the road and checks his mirrors/ blind spots. It only takes a slip of the eye for a second to miss a critical moment on the road.
In fact, ultrasonic sensors have been known to be so sensitive that they have even picked up vehicles moving in the opposite direction. When driving on tight, urban roads this obviously becomes a real problem.
With ultrasonic technology no longer living up to what is required, Vision Techniques have begun to investigate alternative solutions. Video Analytics, used in VT TurnAware, appears to provide the perfect alternative – building on the benefits of ultrasonic technology while remedying its failures.
Unlike ultrasonic technology, which alerts the driver by beeping when an object enters the blind spot, video analytics reveal the full picture. With video analytics, a driver can see where an object is and can judge the situation for themselves.
DVR recording is becoming increasingly important. With criminal activity frequently taking place on Britain’s roads, DVR recording gives drivers that peace of mind, knowing their actions are being properly documented and stored safety. Unlike ultrasonic technology, Video Analytics allow DVR recording – so any event can easily be reviewed to prove liability.
Whereas ultrasonic technology is unable to analyse with much depth, our Video Analytics technology, in VT TurnAware, is able to analyse in great detail. The software can recognise directional change in pixel brightness, motion and distance to distinguish when an object is approaching a vehicle’s blind spot.
The Video Analytics technology in VT TurnAware does so much more than just highlight potential risks in the blind spot. When a vehicle is in motion, the system becomes a lane deviation device, warning the driver if they cross any road markings without indicating. Of course, this is just one of the many additional benefits that VT TurnAware offers.
