I found interesting this comparison between Dutch and American road safety provisions during the last thirty years. Using a different road design philosophy, the Netherlands cut its deaths to 800 from 3,200, while the U.S. went to 37,000 from 44,000. Both drops are admirable, but the Dutch reduction is over twice that of the U.S. (The article says we would need to drop to around 15,000 to have the same level as the Dutch.) The biggest road design differences: "1) They [the Dutch] rejected that wider, straighter and faster is better for non-freeways in urban areas "2) They adopted a multi-modal approach to safety. Travel by bicycle or on foot is valued equally and bikeped accommodations are universal. "3) They are managing access to their “arterials” to a degree that many American access engineers would envy..."
