Results From Three Independent Studies Of Drivewyze’s Smart Roadway Service In Ohio And Indiana
ALBANY, New York, June 3rd, 2025 – Drivewyze by Fleetworthy, has announced the availability of a new whitepaper that reviews results from three recently published academic studies from Purdue University, Cleveland State University with University of Washington in collaboration with the NHTSA, Ohio Department of Transportation and the Indiana Department of Transporation. The studies analyzed the impact of in-cab alerts on truck speed reductions of commercial trucks in Ohio and Indiana. It also projected the ROI in Ohio from issuing the alerts, and how they’ve helped reduce the number of accidents and road congestion (caused by accidents).
The whitepaper is available for download by visiting this page.
“These studies provide a clear picture of how commercial truck drivers reacted when in-cab alerts warned them of upcoming dangerous slowdowns on interstates,” said Brian Mofford, Drivewyze’s VP of Government Experience. “Ohio and Indiana are both partners with Drivewzye and our Smart Roadways service – Ohio has been using the service several years — so we were pleased both states took the initiative to verify their investment in the program through independent research studies. The whitepaper we put together capsulizes the results to educate other states about the potential benefits of implementing similar programs.”
“What makes this program particularly attractive to state agencies is the ability to immediately improve commercial vehicle safety without investing in new infrastructure”

Drivewyze’s partner, INRIX, uses advanced algorithms that analyze millions of anonymous connected vehicles traveling more than a billion miles daily in the U.S. This allows INRIX to identify and monitor traffic slowdowns. The information then goes to Drivewyze and its Smart Roadways platform. Messages such as “Sudden Slowdown Ahead” and “Congestion Ahead” are displayed in-cab devices 2 to 3 miles before the slowdown begins, giving truckers time to slow their speed.
According to Mofford, the alerts work, as cited by the studies. The study “Determination of Effectiveness of Commercial Vehicle Safety Alerts” by Cleveland State University found that secondary crashes involving trucks in Ohio were reduced by 29% over a two-year period when alerts were given to drivers.
“What makes this program particularly attractive to state agencies is the ability to immediately improve commercial vehicle safety without investing in new infrastructure,” added Mofford. “States can activate these alerts across their road network almost immediately, reaching thousands of trucks through our existing connected truck network. Thirteen states are already using our Smart Roadway Traffic Slowdowns service.”
According to another study (“Quantifying the Impact of In-Cab Alerts on Truck Speed Reductions in Ohio” by Purdue University), approximately 22% of drivers receiving sudden slowdown alerts reduced their speed by at least 5 mph 30 seconds after receiving the alert. Twenty-six percent of the vehicles traveling at or above 70 mph at the time of alert reduced their speed by at least 5 mph.
“What’s more important than those figures are awareness and hard braking numbers,” said Mofford. “With the alerts, drivers know something is coming up soon, so they are looking for brake lights and slowing vehicles. This increased awareness can significantly reduce hard braking incidents, making our roads safer for everyone.”
The alerts are available to all drivers, free of charge, through Drivewyze Free, which is supported in collaboration with 48 State Agencies, NHTSA, and NOAA.
