1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.
Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you dont miss important road signs or fall asleep.Most crashes result from human and not mechanical faults.
Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technologysees throughbig vehicles blocking your view.
And improvements to seat belts,pedalcontrols and tyres are making driving smoother and safer.The colour of a car has been found to be linked with safety,as have,less surprisingly,size and shape.
But whatever is in the fuel tank,you dont want a thief in the driving seat and there have been many innovations.Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.
Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyonss personal chauffeur,but their latest efforts suggest that wont be soon.
