While doing some preliminary work with Google Fusion Tables, we created this very basic heat map showing the locations of bicycle-motor vehicle crashes throughout the Metro Detroit region (Oakland, Wayne, Macomb, and St. Clair counties.)

The map does not weight the crashes based on the severity of the injury. Green dots indicate one crash, while orange and red indicate multiple crashes in the same vicinity.

What’s interesting is the distribution. Detroit has noticeably fewer hot spots compared with the surrounding communities.

And some roads have enough crashes that they pop out on the map. That’s true of Gratiot through Macomb County, and to a lessor extent, Woodward through Oakland County.
