Hard-braking events as indicators of road segment crash risk (research.google)

Article summary

Researchers from Google have found a positive correlation between hard-braking events (HBEs) and road segment crash rates, suggesting that HBEs can be used as a leading indicator of crash risk. The study analyzed data from Android Auto and public crash data from Virginia and California, revealing that roads with higher rates of HBEs have a significantly higher crash risk. This finding has implications for road safety assessment and management. The researchers propose using HBEs as a scalable surrogate for crash risk, allowing for more proactive safety evaluation.

What commenters say

• Hard-braking events are a strong indicator of driver risk and can be used to assess insurance premiums.
• The use of hard-braking events as a proxy for driver competence is flawed, as it does not account for situations where drivers are forced to brake hard due to the actions of others.
• Defensive driving techniques, such as maintaining a safe following distance and anticipating the actions of other drivers, can help reduce the risk of accidents.
• The ease of obtaining a driver's license in the US contributes to a culture of distracted and careless driving, leading to a higher rate of accidents and fatalities.
• Insurance companies should consider factors beyond hard-braking events when assessing driver risk, such as overall driving behavior and adherence to traffic laws.
• The use of technology, such as dash cams and driving apps, can help promote safe driving habits and reduce the risk of accidents.
• Drivers who are involved in accidents, even if they are not at fault, may still incur costs and see their insurance rates increase due to the processing and handling of claims.
• Experienced drivers, such as those who have ridden bicycles in heavy traffic, often develop a heightened sense of awareness and defensive driving skills that can reduce their risk of being involved in an accident.
