飲酒運転とスピード違反の防止に役立つ洞察力

(2022年4月13日）-4月は、米国が主催する「飲酒運転撲滅啓発月間」です。 全米安全会議（NSC） to shine a light on the consequences of distracted driving and help make roadways safer. Distracted driving is a leading cause of vehicle collisions, and more than 3,000 people in the U.S. were killed in motor vehicle crashes involving distracted drivers in 2020 alone.

“Distracted driving accounts for nearly 10% of fatal crashes in the U.S.,” said Noah Budnick, Executive Director for Together for Safer Roads. “Adding to this heartbreak is that these crashes are preventable. Distracted driving is a public health epidemic that we must address.”

For fleet safety leaders, coaching drivers on risky behaviors?including distracted driving?is a priority all year round. To help bring awareness to this important safety issue, we looked into Samsara?s data to uncover trends in distracted driving.

Samsara reviewed more than 9.8 million distracted driving alerts from March 1, 2021 to March 31, 2022. We evaluated passenger, light-duty, and heavy-duty vehicles across all industries we serve, including transportation, utilities, field services, and manufacturing, among others. Read on to see our findings, plus a few tips from our community on coaching drivers effectively.

The average speed when a distracted driving event occurs is 55 MPH

Samsara data shows that the average speed when a distracted driving event occurs is 55 MPH. This suggests that most instances of distracted driving events likely occur on highways. Long stretches of road can lead to fatigue or boredom behind the wheel, making it easy for drivers to become distracted. Some drivers may feel they can safely take their eyes off the road for a few moments, but at 55 MPH, you can travel the length of a football field in five seconds.

Distracted driving events occur less frequently on the weekend

When comparing distracted driving events per 1,000 miles driven, Samsara data shows that distracted driving is the most prominent on weekdays, with Monday having the highest amount of alerts, closely followed by Friday. Monday saw a 33% jump in distracted driving events per 1,000 miles driven compared to Sundays. This may be because drivers can experience increased communication, like messages from the front office, and feel the need to provide a timely response.

Distracted driving events occur most frequently in the afternoon

When comparing distracted driving events per 1,000 miles driven, Samsara data shows that distracted driving events occur most frequently in the afternoon between 12 PM and 5 PM. We saw a 25% increase in the number of distracted driving events in the afternoon as compared to the morning. This may be because some drivers are looking for lunch break stops or are sitting in afternoon rush hour traffic.

Drivers speed nearly a quarter of the time for trips between 2 – 2.5 hours

Another leading cause of collisions is speeding. For more than two decades, speeding has been involved in approximately one-third of all motor vehicle fatalities. Speeding is another important safety issue to coach drivers on, especially since distracted driving is particularly dangerous when combined with high speeds. We took a closer look at our recent speeding data from January 1, 2022 to March 31, 2022 and found that speeding is a concern across all vehicle types.

We selected the cohort of trips that lasted between two and two and a half hours to determine how often drivers were speeding during this duration of time. We found that drivers across all vehicle types spent 24% of their trip speeding. Light-duty vehicles spent 30% of their trip duration speeding, the highest in comparison to heavy-duty and passenger vehicle trips. This is likely because light-duty vehicles have the opportunity to easily travel at high speeds and have fewer speeding limit restrictions.

Tips for coaching drivers on distracted driving and other risky behaviors

Ongoing education and one-on-one coaching are important, even for experienced drivers. But without visibility into behavior on the road, coaching is often reactive, and only happens after an incident, collision, or injury has occurred.

?Great fleets with strong safety cultures understand that spending time on employee development is the best way to grow long-term safety awareness and reduce risky behaviors behind the wheel,? said Budnick. ?No human being is perfect. We all make mistakes. For this reason, we need to catch errors and better support the professional drivers we rely on.?

Here are a few tips on coaching drivers effectively:

• Change behavior in the moment with in-cab alerts: One of the best ways to change a behavior is to flag it as it happens. Real-time feedback on speeding, harsh braking events, and other distracted behaviors make it possible to detect and coach drivers on risky behaviors in real time. In-cab alerts can help drivers refocus their attention in the moment and change behavior over time.

• Provide one-on-one coaching to high-risk drivers: For fleets managing hundreds or thousands of drivers, it?s particularly important to focus coaching efforts on the highest-risk drivers. Data on distracted driving and speeding?or safety scores that aggregate a wide array of risk data?can help identify drivers who would benefit from one-on-one coaching or additional training.

• Reward positive behavior with public recognition: Technology should be used as a tool to engage and reward drivers?not as a hammer. In fact, the NSTSCE analyzed video-based driver coaching programs and found that managers ?must provide feedback on safe driving behaviors, rather than only risky behaviors, or the process will be viewed negatively.? Safety-focused companies may offer additional paid time off or bonuses to their best drivers based on the fewest number of harsh braking events or excessive speed warnings. This recognizes good behavior and encourages drivers to do better. Make sure to recognize and reward drivers for following safe practices and improving over time.

Samsara AI Dash Cams can help to build out coaching programs, and in a recent survey of our enterprise customers, 72%* said Samsara has helped decrease distracted driving for their organization. In addition, Together for Safer Roads surveyed drivers and found more than half view themselves as safer and more careful following in-cab camera adoption.

Methodology

• 漫然とした運転: Samsara reviewed more than 9.8 million distracted driving alerts from March 1, 2021 to March 31, 2022. We evaluated distracted driving events from trips where the vehicles were traveling at least 5 MPH. We reviewed passenger, light-duty, and heavy-duty vehicles across all industries we serve, including transportation, utilities, field services, and manufacturing, among others.

• Speeding: Samsara reviewed our recent speeding data from January 1, 2022 to March 31, 2022. We evaluated passenger, light-duty, and heavy-duty vehicles across all industries we serve, including transportation, utilities, field services, and manufacturing, among others. We selected the cohort of trips that lasted between two and two and a half hours to determine how often drivers were speeding during this duration of time. We define speeding as 1 MPH or more over the speed limit.

• *Safety & Sustainability Enterprise Customer Survey 2022: This survey was conducted by Samsara between March 2 and March 17, 2022, using an email invitation and an online survey. The number of respondents per question ranged from 94 to 99, each representing a single enterprise customer. The percentage totals for each question?s results were rounded to the nearest whole number.
