On the relationship between congestion and road safety in cities

We empirically examine the relationship between traffic congestion and deaths in road accidents at the city level. We use panel data from 130 large cities in Europe for the period 2008-2017. We find strong evidence of a quadratic relationship between congestion and deaths in accidents, using both pa...
