School Safety Snapshot


Zendrive has rated the road safety around 75,000 schools nationwide. Using mobile phone data from car drivers Zendrive has measured the levels of dangerous driving around schools across the United States. You can find out the Zendrive ratings for dangerous driving around your local schools on the Zendrive School Safety Snapshot interactive map.

The map uses three different administrative levels to show ratings for states, counties and individual schools. When zoomed out on the map you can view the ratings for each state (California and Florida have the worst ratings). If you click on a state on the map you can drill down to view the ratings in each county. If you the click on a county you can view the ratings for all the individual schools.

The interactive map is well designed and it is very easy to navigate down to view the ratings for individual schools. I'm not entirely convinced about Zendrive's data and methodology. They claim that their model "predicts future collisions six times more accurately than leaders of the industry". If you are worried about dangerous driving around your local school then it might be worth checking the traffic accident records of the local roads for yourself.


For example you could look at Mapping Ten Years of Fatal Traffic Accidents, an interactive map showing every single fatal traffic accident in the United States from 2004 to 2013.

When zoomed out this map shows a heatmap of fatal traffic accidents across the whole country. When you zoom in on the map markers appear showing the location of each individual fatal accident. This means that you can zoom in on any city or town in the USA to view a detailed map of where accidents occurred locally.

When you zoom in on the map option controls also appear which allow you to filter the accidents shown by contributing factors (alcohol, speeding and driver distraction). The markers are also colored on the map to show who was killed in each accident (driver, passenger, pedestrian etc).
