ABOUT

DiExSys stands for Diagnostic Expert Systems. We founded our company in 2006 to do one thing:  Work alongside our clients toward a shared vision of preventing injuries and deaths on our roads. This remains our singular purpose today. 

Our engineers and scientists provide expert advice, policy guidance and decision support analysis on highway safety and traffic operations related matters to numerous State Departments of Transportation, cities, counties and public road authorities throughout the US and abroad.

We hold the strong belief that professional authority rests on substantive scientific knowledge, and that only when such knowledge is obtained can the transportation engineer act with social responsibility. 

Our culture is rooted in applied research, deep data analytics and the pursuit of safety insights and breakthrough innovation. DiExSys has a proven record of translating state-of-the-art statistical techniques into applied methodology used by practicing transportation engineers and planners.

DiExSys Vision Zero Suite (VZS) is a Highway Safety Manual (HSM)-compliant safety management system that harnesses the power of predictive analytics and pattern recognition to produce the augmented intelligence needed for effective road safety management. DiExSys VZS guides our clients on their journey toward our shared vison of zero traffic fatalities.

Transportation professionals across the US, Canada, Italy, Australia and Japan make use of our applied research findings and methodologies to design and build safer roads.
