“SELF DRIVING TRUCKS AND CAR BREATHALYZER”
Nowadays, there are many traffic collision happens in all over the world. The main causes are usually tiredness, sleepy and drunk driver.
According to the National Sleep Foundation’s 2005 Sleep in America poll, 60% of adult drivers – about 168 million people – say they have driven a vehicle while feeling drowsy in the past year, and more than one-third, (37% or 103 million people), have actually fallen asleep at the wheel! In fact, of those who have nodded off, 13% say they have done so at least once a month. Four percent – approximately eleven million drivers – admit they have had an accident or near accident because they dozed off or were too tired to drive.
The National Highway Traffic Safety Administration conservatively estimates that 100,000 police-reported crashes are the direct result of driver fatigue each year. This results in an estimated 1,550 deaths, 71,000 injuries, and $12.5 billion in monetary losses. These figures may be the tip of the iceberg, since currently it is difficult to attribute crashes to sleepiness.
- There is no test to determine sleepiness as there is for intoxication, i.e. a “Breathalyzer”.
- State reporting practices are inconsistent. There is little or no police training in identifying drowsiness as a crash factor. Every state currently addresses fatigue and/or sleepiness in some way in their crash report forms. However, the codes are inconsistent and two states (Missouri and Wisconsin) do not have specific codes for fatigue and/or fell asleep.
- Self-reporting is unreliable.
- Drowsiness/fatigue may play a role in crashes attributed to other causes such as alcohol. About one million such crashes annually are thought to be produced by driver inattention/lapses.
According to data from Australia, England, Finland, and other European nations, all of whom have more consistent crash reporting procedures than the U.S., drowsy driving represents 10 to 30 percent of all crashes.
It is very difficult for drivers to accurately assess their own level of fatigue. The ability to self- assess becomes increasingly impaired as you get more fatigued, however the self-confidence in this ability remains. Nevertheless, there are some warning signs to look out for, including:
- Trouble focussing, or narrowing of attention
- Head nodding, or inability to keep the eyes open
- Not remembering the last few minutes
- Poor judgement, slower reaction time
- “Zoning out”
- Daydreaming and wandering thoughts
- Constant yawning or rubbing your eyes
- Drifting in the lane
Keep in mind that if you are experiencing any of these symptoms of driver fatigue, it is very likely that your driving performance is already impaired.
To prevent the crashes, my idea is to implement the self driving trucks, because the will be no need of driver in context of logistics driver. Long journey will surely affect the driver and driver need to have proper rest throughout the journey.
Logistics make the world go round. They’ll be cheaper to run than regular rigs, driving more smoothly and so using less fuel. Computers never get tired or need comfort breaks, so they’ll run longer routes. And they could drive in convoys, nose-to-tail, to minimise wind resistance. On the downside, it could put drivers instantly out of work, and even staff at the truck stops set up to service them, but om the trucks we might still need a human passenger to ensure their cargo is safe,but the workload is greatly reduced.
For passenger cars, in which the drivers are usually get drunk while driving, I propose to install a system that is helped by the sensors in the dashboard. This system will prevent the car from running if the alcohol level in the drivers blood is over the standard in only one seconds. The maximum tolerance for above 21 years is 0.8, meanwhile we can also set the system for the drivers aged below 21, set to zero tolerance. If the limit is exceeded, the car will not run. There are two types of sensor, the first one is the Breath Based system and Touch Based system. Breath sensor will analyze the molecule (Carbon Dioxide & Ethanol) from the breath of the driver. The result will show the results in the HUD, warn the drivers with 3 meter with specific colour (Green, Yellow and Red). The other one is the touch based system,the sensors will be located in the most touched objects/components by the driver, such as steering wheel or start stop button in a car. Because alcohol affect the skin, the sensors will read the driver’s skin in order to determine the level of alcohol.
