On a crash course : the dangers and health costs of deficient roadways. A study commissioned by the Transportation Construction Coalition.

While considerable research has been conducted over the past 50 years quantifying the significant roles motor vehicle design, drunk and drugged driving, speeding and non-use of seatbelts play as factors in the number, severity and economic costs of motor vehicle crashes in the United States, this is the first national study in many years to examine the role and consequences of another major factor in these tragic incidences—the physical condition of U.S. roadways. The study finds that the cost and severity of crashes where roadway conditions are a factor “greatly exceeds the cost and severity of crashes where alcohol or speeding was involved, or the cost of non-use of seatbelts.” (Author/publisher)
