The roads are not the same

Driving behavior during the pandemic has changed more than simply how much we drive.

It seems like there are so many changes happening right now that its hard to keep up. As we try to balance a return to normal alongside the continued risks posed by COVID-19, America is entering a new phase of its response to the COVID-19 pandemic.  

Some cities have reopened restaurants and parks and other businesses, while others are still enforcing broad social distancing policies. On top of the response to the pandemic, people are coming together to demand solutions for the racial and economic inequality that Black Americans face. These historic events interact with each other in complex ways. 

In prior posts, we discussed the drop we saw in core driving metrics, such as miles driven, in response to the pandemic, and how differences at the local level, rather than the state-level, are the real story. Since then, we have seen an upward trend in miles driven and many areas are now returning to pre-COVID-19 levels of driving. In fact, in states like Wyoming, we are actually seeing more traffic than we’d expect due to increased tourism as national parks reopen.

We know that driving risk is measured not only by how long people are on the road but also by the choices people make during tripsDriving safely includes limiting your speed, predictable and smooth acceleration, and decelerationavoiding highrisk hours, and, of course, setting down the phone!  

At Arity, we are passionate about using data from sensors in phones and vehicles to understand driving and accurately identify risky behaviors in order to make roads safer and insurance pricing more transparent and accurate for everyone.  In the chart included belowwe can see how certain behaviors have changed throughout the pandemic. Here are some highlights:  

  • The pandemic hasn’t changed how frequently we use our phones while driving, which is way too often.  
  • Aggressive driving behaviors such as sudden acceleration and braking are down as roads have become less congested.  
  • People are speeding more on both side streets and highways, including driving over 100 mph more frequently than they did pre-COVID-19.

As with mileage, we see a variance in behaviors between states. For example, in Texas and New Jersey, we see different responses to the pandemic likely due to different road conditions and driving cultures.

The Arity Drivesight score combines these different driving behaviors into a single measure of driving risk that is highly predictive of insurance lossesWe score the trips across all drivers each day to get a view of how the driving risk on the roads is evolving during the pandemic. We find that driving risk per mile driven increased a small, but noticeable, amount during the height of the response to the pandemic.

Going beyond predicting driving risk, Arity also measures some outcomes directly. The Arity crash detection service uses machine learning algorithms and sensors on mobile phones to detect potential crashes. Arity customers use crash detection to alert friends, family, and sometimes even emergency services of potential accidents. For this analysis, we used the data from the crash detection service to see how the frequency and severity of crashes is changing.

Unfortunatelythe percent of highspeed crashes is increasing. This is important because we know crashes at higher speeds are more dangerous than those at low speeds and typically result in more injuries and damageThis is one possible cause for the 14% increase in the fatality rate per mile recently reported by the National Safety Council.

As people return to pre-COVID-19 driving levels, we must watch whether their driving behaviors also return to previous levels. This will be a crucial insight in order to stay on top of the actual outcomes that insurers will have to manage.

Until next time  stay safe on the roads!
