Number of people and number of persons per 100,000 residents who are killed or sustain serious injuries in traffic crashes


Vision Zero is our community's goal to achieve zero traffic-related fatalities or serious injuries. Every data point here represents a family member, a friend, a neighbor - real progress on this measure means fewer people in our community experiencing life-changing incidents which are mostly avoidable with improved policies, increased traffic enforcement, engineering design, and driver behavior.


The data from 2020 show a 22% decrease in serious injuries and 5% increase in fatalities on our roadways compared to 2019. We know this was a result of major changes in roadway activity and drivers’ behaviors, primarily due to the various impacts of the COVID-19 pandemic on our economy and the health and safety of our community. And, throughout 2020, Austin Transportation continued to make investments in engineering treatments and changes to operations to make high priority crash locations safer as well.  Find out more at

Additional Measure Insights

In August 2020, the Austin Transportation Department released Vision Zero Viewer, which allows people to view crash data by month, year, transportation mode, demographic groups impacted, time of day, and geographic location. Visit Vision Zero Viewer here.

Measure Details and Definition

1) Definition:  Vision Zero is a strategy to end traffic fatalities and severe injuries, while increasing safe, healthy, and equitable mobility for all. This measure tracks how many persons per 100,000 residents are killed or sustain serious injuries in traffic crashes. 

2) Calculation method: The number per 100,000 residents who are killed or seriously injured in traffic crashes was calculated for each year separately by using the following formula:

((k + a) /p)*100,000
k = number of people killed 
a= number of people seriously injured
p = population of the City 

The population of the City for those years was sourced from Austin Area Population Histories and Forecasts.   

3) Data Collection Process:  The original data is sourced from Texas Department of Transportation's CRIS database and is supplemented with staff analysis from the Austin Transportation Department.  This Vision Zero dataset includes official crash reports (CR3s) only for crashes occurring within the City of Austin, regardless of the public safety jurisdiction who responded to the crash. ATD’s database is continuously updated, so reports run at different times may produce different results. Fatalities are derived from original CRIS data and may update without notice. Serious injuries that resulted in a fatality at a later time may not be reflected in the results.  Crashes in this dataset are based on having a reported person involved in the crash. Some crashes that are considered a hit-and-run with no person will not be included. Crash numbers may change between January and June of each year as the Austin Transportation Department reviews and refines Vision Zero crash data that comes from the State of Texas.

4) Measure Target Calculation: The data was calculated using the past five years worth of data, from 2016 through 2020. The goal of the Vision Zero program is zero fatalities and serious injuries, and without systemic changes driving down the numbers dramatically, we will note that we are off-track towards the goal of zero.

5) Frequency Measure is Reported: Annually (Calendar Year)
