Wayne State University doing highway speed limit study for MDOT


DETROIT (WKZO) -- Researchers from Wayne State University are conducting a study on highway traffic patterns in Michigan -- specifically, how they pertain to large trucks. Professor of Civil Engineering Peter Savolainen says that Michigan is one of the few states that still has different highway speed limits for trucks than for regular cars, and it may be time to change those rules.

He tells us that those differential speed limits were created back in the 1950s and 60s, when it was thought that since trucks need more time to stop, this arrangement would be safer. However, that may no longer be the case.

The researchers will talk with truckers, collect national data, and do field studies to estimate what would happen to traffic, accidents, and air quality if Michigan dropped the slower speed limit for trucks. They'll report back to MDOT later this year.
