Traffic Engineering Services

For more than 59 years, the National Transportation Safety Organization (NTSO) has taken a unique, data-driven approach to road safety by analyzing traffic crash data, identifying high-risk locations and trends, and helping develop targeted safety projects. Over time, these individual improvements contributed to dramatic reductions in traffic fatalities and serious-injury crashes within NTSO member communities. To provide the technical expertise necessary to identify safety concerns and develop effective countermeasures, NTSO has a licensed and insured Professional Engineer (P.E.) specializing in traffic engineering on staff.

NTSO's approach and long-term results are unique not only in the United States, but worldwide. In one of its primary focus areas, Oakland County, Michigan, NTSO led a sustained transportation safety effort that achieved one of the lowest traffic crash fatality rates in the world. Despite significant growth in population and traffic volumes over the decades, the county's traffic fatality rate has fallen dramatically. This success demonstrates the value of a comprehensive, long-term approach that combines crash data analysis, traffic engineering, education, enforcement, emergency response, technology, and strong partnerships among government agencies, businesses, and community leaders.

NTSO has also been a longtime supporter of Intelligent Transportation Systems (ITS) and emerging transportation technologies. At various times, NTSO served on the Board of Directors of ITS Michigan and managed the statewide organization. From supporting the successful implementation of the Road Commission for Oakland County's FAST-TRAC adaptive traffic signal system to collaborating with the Michigan Department of Transportation (MDOT) and automotive companies on education and technology initiatives, NTSO has remained at the forefront of advancing innovative approaches to transportation safety.

NTSO strongly believes that technology, combined with sound engineering, quality data, and collaboration, will continue to play an increasingly important role in preventing crashes, reducing fatalities and serious injuries, and creating safer transportation systems for the future.

At this time, NTSO's traffic engineering services are available exclusively within the State of Michigan.
