Traffic study sees shades of gray in yellow lights

More on risk compensation from WaPo Traffic study sees shades of gray in yellow lights summarizes a study from U of Cincinnati

The longer the yellow persists, the more likely it is that drivers will not stop, said Zhixia Li, an engineering PhD student who worked on the study with his professor Heng Wei. In fact, he said, with a long yellow, "stopping is more dangerous," because other drivers are likely to keep going through the yellow, and someone who opts to stop runs a greater risk getting hit from behind.

The WaPo article doesn't actually say this is risk compensation, but drivers familiar with an intersection will be familiar with the length of yellow, and the longer the yellow on average the greater the chance of making it.
