The primary objective of this research effort is to determine if there has been a statistically significant change in traffic collisions (total, fatal, fatal plus injury, wet pavement, and nighttime) due to recent speed limit increases on California state highways. Analysis of both collision counts and rates was performed for speed limit increases from 55 to 65 mph, and from 65 to 70 mph that occurred at the beginning of 1996. A comparison groups of highways that remained at 55 mph was also developed. The Analysis of Variance (ANOVA) and an Observational study by Hauer, the primary methodologies, revealed very similar results especially for statistically significant increases in total and fatal collision rates and counts.
