Cell Phone Notifications Are A Distraction Too
July 23, 2015
We all know that talking on a cell phone or reading and sending text messages while driving is a major distraction for drivers but it turns out that just receiving notifications are distracting too, even if the phone calls or texts aren’t answered or read.
This finding was described in a study conducted by researchers at Florida State University (FSU) and published in the Journal of Experimental Psychology: Human Perception and Performance.
To conduct their study, the FSU researchers had volunteers participate in a computerized exercise to determine their ability to concentrate and complete assigned tasks. Once that test had been completed and the results recorded, the volunteers were given the test again. In the second test, the volunteers were randomly assigned to three groups; no notifications, call, or text.
During the second exercise, the researchers called or sent text messages to the assigned volunteers. The volunteers weren’t aware that the calls and texts were part of the study or that the notifications were generated by the researchers.
The results showed that, even though they didn’t respond to the calls or texts, those volunteers who heard or felt the vibrations from the call or text notifications made more mistakes on their computerized tasks than those who didn’t receive any notifications. The results showed that, among those who received a notification, their chances of making a mistake were three times greater than those who didn’t receive any notifications.
According to the researchers, the study shows that the notifications were enough to distract an individual from concentrating on the task at hand. Comparing their data to other studies on the subject, the researchers concluded that just receiving notifications can be as distracting as actually answering the phone or a text.
While not tied specifically to driving, the study shows that drivers, especially those who may find themselves in situations where their concentration is needed most (construction zones, narrow roads with heavy traffic, etc.), could possibly be distracted enough by phone notifications to make a critical mistake on the road.
For drivers, the best bet is to turn the cell phone off while driving.

My Car Does What Offers Info On New Car Safety Technology
July 22, 2015
For those with a new car or those considering the purchase of a new car, My Car Does What.org offers an explanation of new car safety technologies available in new vehicles, including some that buyers may not have been aware were available.
Funded by the Toyota Safety Research and Education Program Settlement the site was developed by the National Safety Council and the University of Iowa. With new car safety technologies entering the market at a rapid pace and older technologies being updated, the website is designed to inform vehicle owners about the different technologies and teach drivers how to use them.
A lot of new car safety technology is getting a lot of press such as crash avoidance and lane departure systems but some new safety systems may be surprising to drivers including:
- Terrain management – adjusts speed and suspension systems when moving from paved to unpaved roads.
- Hill descent assist – aids drivers balance the need between braking and speed depending on the degree of the downhill grade.
- Hill start assist – When stopped facing uphill, keeps the car from rolling back by holding the brake until the gas pedal is activated.
- Health and workload monitoring – Monitors a driver’s vital signs and can alter car functions during a health emergency.
- Cornering braking control – Adjusts the brakes independently to keep the car on the road if a driver is approaching a sharp curve or corner too fast.
Other explanations of new and updated car safety systems include:
- Anti-lock braking
- Forward collision warning
- Adaptive and active suspension
- Adaptive headlights
- Automatic emergency braking
- Electronic braking assistance
- Obstacle detection
- Pedestrian detection

Driving Dehydrated And Without Rest Like Driving Drunk
July 21, 2015
Two studies from researchers in Great Britain show that driving while dehydrated and driving too long without a break on long trips can be dangerous.
The first study conducted by researchers at Loughborough University in England looked at the effects dehydration had on drivers. The researchers conducted a two-day experiment to compare driving abilities when drivers were hydrated and dehydrated. On the first day subjects who were properly hydrated were observed while driving on a simulated driving course. According to the researchers, the hydrated drivers had 47 driving incidents. On the second day, when the subjects were dehydrated, the number of incidents more than doubled to 101 incidents.
According to the researchers, the number of driving incidents recorded by those subjects that were dehydrated were equivalent to someone operating a vehicle with a blood alcohol content of 0.08, the legal limit in both the UK and the US. The incidents recorded included, lane weaving, braking late, and not stopping at the stop line at intersections.
According to WebMD.com. some of the symptoms of dehydration can include:
- Palpitations (feeling that the heart is jumping or pounding)
All symptoms similar to alcohol intoxication.
Another poll conducted by IAM, a British highway safety organization, shows that drivers tend to drive too far between breaks on long trips. According to the drivers polled, 65 percent didn’t stop for breaks on long trips because they didn’t feel they needed to. Seventy- nine percent of the drivers polled said they wouldn’t stop unless there was a rest stop conveniently located on the highway.
The stresses of dealing with highway traffic along with what’s known as “highway hypnosis” can cause a driver to become fatigued and lose his or her focus on the whole driving picture. Without those refreshing breaks, fatigue can easily set in and, as shown by the research mentioned above, becoming dehydrated can lead to driver errors.
Whether they feel the need or not, drivers should stop at least every two hours or 100 miles to rest and refresh themselves. stopping for a short break to relax and have a drink can help a driver avoid fatigue and the problems caused by dehydration.
Drinking caffeinated drinks are fine if you want to fight off fatigue but caffeine has a diuretic effect that causes the body to lose fluids. To make the most of your rest breaks, alternate drinks between caffeinated drinks such as coffee or cola and non-caffeinated drinks such as water or fruit juice. Avoid highly caffeinated “energy drinks” at all costs.

Older Drivers Can Be Aided By Technology
July 17, 2015
When it comes to older drivers, stereotypes aren’t necessarily true. Years ago, safety experts predicted a traffic nightmare as baby boomers reached old age but that hasn’t turned out to be the case. In fact, traffic data from the Insurance Institute of Highway Safety shows that traffic deaths among drivers 70 and older have been on a steady decline since the high point in 1997.
There are fewer drivers over the age of 70 and they tend to drive fewer miles. Safety experts feel that many older drivers “self regulate”; that is they tend to restrict driving to less busy times of the day and they avoid driving at night. Another reason for the decline in deaths of older drivers is that older drivers tend to be healthier and have better medical care than drivers in the past.
It’s impossible to tell at what age a driver is too old to drive. It depends on the individual driver and everyone ages at a different rate. A new study published recently tracked 1000 people born in 1972-73. Using a range of biomarkers, they found that the biological age of the one-thousand 38 year olds ranged from 30 to 60 years apart. Some were aging rapidly while others aged very slowly.
Still, it’s undeniable that most people will reach an age when they’ll no longer be able to drive and many families will face the difficult decision of when to take away the keys.
However, for those drivers reaching their 70’s and still driving safely, technology has the answer to help them to continue to drive safely and, hopefully, reduce the fears that any family members may have. If they can afford it, a new car with the following features can help to keep them and any other driver, regardless of their age, safer on the road. While these packages may cost a bit more, their price may be offset by a reduction in insurance costs.
- Collision Avoidance – Collision avoidance technology uses a combination of either radar, lasers, and cameras to keep an eye on vehicles and pedestrians ahead. Those systems work together to warn a drivers if they’re approaching too closely to another vehicle or object. If the driver doesn’t heed the warnings, the system will apply the brakes and stop the car.
- Lane Departure Warning and Prevention – This system warns a driver if the vehicle is drifting out of the lane and uses the dynamic braking system to steer the car back into the lane if the driver doesn’t take action.
- Adaptive Headlights – This system turns the headlights in the direction of the wheels to illuminate the road more clearly on curves.
- Blind Spot Detection – This system uses sensors to detect other vehicles in a driver’s blind spot to warn a driver who’s about to move into another lane or who may be drifting over the line. These systems can either warn the driver or work together with the lane departure system to prevent a driver from moving over.

Computer Display Screens In Cars Add To Distractions
July 8, 2015
Computer display screens that automakers are adding to their new models are going to add to the distractions on the road according to experts. The screens, which are tablet size, are supposed to fulfill all the functions of a smartphone.
Both Google and Apple are making built-in computer display systems for cars and automakers seem to be rushing to get them installed and out to potential buyers. According to the automakers, it’s what the customer wants.
Google is producing an Android based system called Android Auto and Apple is producing an iOS operated system they’re calling Apple CarPlay. Both systems are designed to sync with and provide all of the features available in a smartphone including, email, twitter, streaming music and maps. Other apps are also available and more are sure to be added as time goes on.
The computer makers claim that the built-in display screens, some of which feature no-touch and voice activated controls are safer for drivers to use than trying to get all the same information while holding a phone. That may be true in some cases but only to a small degree.
Using these display screens will still require a driver to look away from the road ahead and look at the screen, even if only for a couple of seconds. At 45 mph, a car will travel 132 feet in two seconds and a lot can happen in that distance and time.
According to researchers, voice-activated systems aren’t that safe. Studies have shown that a voice activated system like Siri can cause even more distraction than a hand-held phone. Part of the distraction comes from the frustration of dealing with a voice-activated system that doesn’t understand what you want or displays the wrong information.
When it comes to voice activated texting, researchers in Texas found that, if a driver chose to visually verify the contents of a text, the voice activated systems offered no safety advantage over manual texting.
The problem comes in the skills and brain functions needed to drive. Those are:
- Visual – Keeping your eyes on the road ahead and watching for signals or potential hazards.
- Manual – The manual act of steering and operating the pedals.
- Cognitive – Using your mind to interpret what you are seeing and to make minor or major changes in steering, speed, or both depending on what’s happening on the roadway.
All three of these skills and functions must act together in order to drive safely. If one or more are involved in another activity, driving becomes much more dangerous:
- Whether using hand-held phones or built-in display screens, to make choices, your vision is focused on the display screen and not the road ahead.
- While formulating a response to a text message or carrying on a phone conversation, your cognitive abilities are tied up in the act of texting or listening to the other person and your ability to make rapid decisions regarding the traffic situation is diminished.
- When waving your hand over a display screen to look for or make a music selection, you’re using all three of the functions and skills that should be focused on the very important job of driving.
Many drivers will find, much to their regret, that these display screens don’t add any appreciable degree of safety and they may make the road much more dangerous.
