Connected vehicle data offers a scalable and cost-effective solution that can revolutionize the way we approach roadway safety. 

The status quo of relying on crash data to assess safety is no longer sufficient. To truly transform the way we measure and improve roadway safety, we must tap into the power of connected vehicle data. By utilizing this resource, transportation agencies can effectively and affordably identify safety risks and address potential issues before they escalate into fatalities. 

Traditional methods of measuring safety rely on measuring infrequent and often devastating events like crashes or fatalities. This data is readily available to agencies, however they often don’t provide sufficient information by themselves on roadway safety.

Crashes don’t just come out of nowhere - 90% of crashes are a direct result of risk-taking driver behavior. This is the “safety funnel”, it shows how these behaviors can escalate into an evasive maneuver, a near-miss, a crash, or a fatality.

Later events in the funnel are more severe, but they are also less frequent. Fatalities, for example, happen once in every 76 million miles driven in the US. This means that, on average, for a 1-mile stretch of road: the average risk of a fatality in a given year is 0.00000132%, or a frequency of once every 50 years. With numbers this small, it is difficult to measure and predict risk accurately.

For accurate statistical analysis, you typically require a sample size of 30 or above. If you were to use metrics later in the funnel, it would take a considerable amount of time to identify whether your safety measure worked or not. For example, if you were measuring safety using fatality data, it would take 1500 years to get 30 samples. However, if you were measuring risky behaviors, it would take just 90 minutes. The faster you can measure safety, the faster you can improve it.

Using metrics later in the funnel also creates higher costs. Relying on crash and fatality statistics carries a high human cost, up to $11,449,000 per incident, whilst detecting near misses using camera-based technologies can cost up to $80,000 per unit to deploy. It's time to shift our focus to the top of the safety funnel, where we can measure risky behavior and discover safety issues before crashes occur.

At Flow Labs we focus on helping transportation agencies measure risk-taking behaviors directly. We leverage data from multiple sources, including connected vehicle data, to identify and analyze safety issues.

Advances in connected vehicle data, provided by companies like Wejo, make it possible to measure and understand vehicle behavior from over 13.8m vehicles across the US, with over 750bn miles traveled, giving transportation agencies the power to identify safety issues quickly and effectively. This data can provide deep insights into various safety-related behaviors and allow agencies to measure the impact of their safety measures in real-time.

The key leading indicators of crashes have been well known and well researched for decades, bringing a clear understanding of some of the key leading indicators of crashes:‍
