The objectives of this research was to determine the effects of raising and lowering posted speed limits on driver behavior for urban and rural nonlimited access highways. This report was prepared for the Federal Highway Administration

This study reviewed the principles and practices used to set speed limits. It is based mainly on a survey of traffic officials conducted by the American Association of State Highway and Transportation Officials (AASHTO) subcommittee on Traffic Engineering. All States and 44 city and county agencies responded to the survey

A Study by the Cato Institute showing that the repeal of the 55 NMSL didn't result in more deaths.

This report describes the findings of a study conducted to determine if including factors in addition to the 85th percentile speed could increase the effectiveness of Michigan's speed zoning procedure as measured by improved safety and increased driver compliance.

This study analyzes state-by-state fatality data published by the National Highway Traffic Administration (NHTSA), derived from the Fatal Analysis Reporting System (FARS) and the Federal Highway Administration (FHwA). These data are collected and reported using a Federal Fiscal Year (FFY) beginning on September 1 of each year.

The New Jersey Department of Transportation (NJ DOT) three-year study of their 65 mph speed limit has been released. The study supports expanding the 65 mph speed limit to cover approximately 75 percent of limited access highways

The new information shows that fatalities have more than doubled on rural interstates and has also increased on rural primary highways. This information contradicts the state officials who claimed speed limits, higher fines, and more enforcement would lower traffic deaths
