The paper describes the results of an investigation into the relationship between traffic deaths and the speed limits in California. The Caltrans investigation analyzed statewide accident and travel statistics for periods before and after an increase from 55 mph to 65 mph on rural Interstate highways. After setting an historical perspective, the discussion will describe the routes studied, it will present the results of various before and after speed studies, it will describe the data sources for the accident and travel statistics, it will present statistical validity tests of the before and after mileage death rates, and it will conclude by discussing the significance of the major finding that there was no statistically significant change in the number of traffic deaths.
