Phone use study finds Oregon drivers are “least distracted” in America

Posted by on April 18th, 2017 at 9:22 am

Using a cell phone while driving is a dangerous, selfish, and illegal behavior that has become far too common.

A company that uses sensors in smartphones to study driving behavior has revealed startling — yet unsurprising — facts about Americans’ selfish attitudes while behind the wheel of their cars: People use their phones during 88 out of 100 trips. When extrapolated out for the entire U.S. population, that number shoots up to about 600 million distracted trips per day.

In what they bill as the “largest and most robust driver phone use study done to date on the planet,” Zendrive analyzed three million drivers and 570 million trips over a three-month period.

While what they found is unnerving to say the least, Oregon drivers came in as the “least distracted” in the entire country. By calculating the average amount of time drivers use their phones everyday divided by the average time they drive everyday, Zendrive determined that Oregon drivers used their phones while driving 3.7 percent of the time. The most distracted state was Vermont, whose drivers used their phones 7.4 percent of the time.


Phone use by state shows that westerners tend to be less distracted.

The study also found that of the ten states with the lowest distraction levels, six have laws that ban hand-held phone use (and so does Vermont, for what it’s worth). Overall, the impact of cell phone laws on driving behavior remains inconclusive.

On a citywide level, Portland came in 10th out of 15 cities. Los Angeles had the most distracted drivers and Seattle came in as least distracted.

Another way to look at the data is that during an hour-long trip, drivers spent an average of 3.5 minutes on their phones. “This finding is frightening,” the report authors said. “Especially when you consider that a 2-second distraction is long enough to increase your likelihood of crashing by over 20-times. In other words, that’s equivalent to 105 opportunities an hour that you could nearly kill yourself and/or others.”

If the performance of Oregon drivers isn’t enough to give you a bit of solace, you might be interested to know that Zendrive isn’t just a faceless company that just crunches numbers. They’re an advocacy group that’s fully behind Vision Zero and they’re actively working to help cities reduce — and eventually eliminate — traffic deaths. “Zendrive is working with communities, local decision-makers, safety experts and driving coaches to use our data to save lives,” their website reads. “If you can measure it, you can manage it.”

And Zendrive’s Director of Public Policy & Government Affairs is Noah Budnick, a veteran active transportation advocate who formerly served as executive director of the San Francisco Bicycle Coalition and deputy director of Transportation Alternatives in New York City. As a member of NYC Mayor Bill de Blasio’s transition team, Budnick is credited for helping introduce the first Vision Zero policy in America.

    Enforcement seems a very low priority, perhaps because cops themselves are set up to be the most distracted of all given the technology stuffed into their cars. I can’t imagine that has any effect on their predisposition to cite others….

    Although the differences between states seem slight, one wonders if there is any way to correlate usage rates and crashes-that-may-be-linked-to-distraction? It also seems like phone-linked distraction in city driving would be far more important than on the freeway or open road.

    “By calculating the average amount of time drivers use their phones everyday divided by the average time they drive everyday, Zendrive determined that Oregon drivers used their phones while driving 3.7 percent of the time.”

    Wait- am I missing something here? So the data assumes that if I have a 10 minute phone call before bed (and that’s my only use of my phone for the entire day) and I drive 10 minutes around the block and leave my phone in my back seat, I’m still assumed to have spent 100% of my time while driving on my phone. It seems like just calculating how much time people drive by how much time a phone is used during the day isn’t a very strong data connection since they could be entirely unrelated… What am i missing here?

      I assume they can compare phone in use and phone in motion to calculate those figures.
      Now whether they can differentiate phone in motion while biking or walking from phone in use while driving I don’t know.

        That’s what I was trying to figure out. Often when I’m a passenger in the car with my partner I assume the role of “DJ” and “navigator” which means fiddling with the phone. Given the methodology of this study I sounds as though it would flag the trip as distracted driving. It may or may not be, but I do feel it saps the study of validity. It’s a good starting point if nothing else and if these potential shortcomings are actually present future studies can improve on the methodology.

          Right? I think this is really important data to gather since it’s a huge problem and I don’t know that it helps the cause to use a methodology that is seems like an enormous stretch between their ‘data’ and findings.

          Now if this data was collected by phone in use while in motion (even if it happens to capture passengers), I would be far more interested in these numbers.

      From the study executive summary:

      “Our data science team looked at the relationship between how long people drove each day and how much time they spent using their phones while driving. They calculated the ratio between the average daily trip time and the average amount of time drivers used their phones each day.”

      So the calculation was done using phone use while driving. What I would like to know is how they determined the difference between passenger phone use and driver phone use.

    Nope! As a TriMet operator, from my elevated perch, I see at least half of drivers next to me on their phones, either talking, texting, or otherwise focused on that little screen. Several times a day I wait at traffic lights behind a motorist, the light turns green, no movement. Seconds pass, no movement. Tap the horn and they finally put down their phone and go. I see phones being operated from dash mounts, on the steering wheel, in laps, on the horn of the steering wheel, in the left hand, in the right hand, in both hands while steering with knees and in the seat next to them. Sorry, this study may have its scientific merits, but the reality on the road, as I see it with my eyes, is quite different.

    What constitutes use? Before I set off on my morning drive to work, or my evening drive home, I open up the map app and set my destination (which gives me the optimal route home/work avoiding traffic), and my music is streaming while I drive. I don’t answer texts/e-mails, or look at notifications and rarely make or receive a phone call with the hands free mode.

    Does this mean I am “using” my phone while I am driving?

        I decided a long time ago that if I was ever a driver in a motor vehicle collision where someone was injured or killed I wanted to be stone cold sober and to have been fully focused on the task at hand (driving). I also avoid speeding (using cruise control most of the time and always on highways), running yellow/red lights, etc. It’s not hard and I usually get to my destination in ample time. It’s not hard.

        It’s a shame that our legislature’s commitment to motorist entitlement has led to the amendments that water down the original bill, but I’m not at all surprised. The bill is still better than nothing as amended.

        Now if only we could actually enforce this and other traffic laws. I feel our lack of enforcement is a large part of where the entitlement that motorists display comes from, which in turn keeps us from getting any enforcement or laws with teeth.

    I find the study results believable. Here in Minnesota, where there is no handsfree law, and where the study put us more or less in the middle (i.e., nearly twice as distracted as Oregon), people are WAY more brazen about using their phones when they drive. You see it on the streets of Minneapolis way more than you do on the streets of Portland. Not to say it isn’t bad in Portland, but it’s much worse here. And apparently much of the country is significantly worse yet. Yecch.

    I used to oppose handsfree laws such as those in OR and WA on the basis that talking on a handheld isn’t any more distracting than talking on a handsfree phone (which is true), but I’ve come to realize it’s difficult for law enforcement to prove someone was texting while driving, but relatively easier to bust them for using their phone. So the handsfree law is an incredibly powerful enforcement tool.

    Pdxbusman, you may be right that way too many drivers are distracted in Portland – it’s an epidemic everywhere – but you might try driving a bus in a few other states and see how much worse the distraction is everywhere else.

      A law prohibiting all cellphone use may be harder to enforce for hands-free users, but it would not be any less powerful against in-your-hands users. I think the real reason for permitting hands-free cell usage is political. At the time the law was passed (and maybe still today), people were arguing the issue was hands-on-the-wheel/eyes-on-the-road, though we have clear data the real issue is mental distraction.

        Well, of course a law prohibiting all cellphone use would be preferable. But a handheld ban is much more politically doable, which is why it’s what got passed in OR/WA and what’s being currently proposed in the MN legislature. No question a total ban would be preferable, and may eventually happen.
